Geological structure and Mesozoic-Cenozoic tectonic evolution of the Nenya-Chumysh basin (Southern Salair, southern Western Siberia)

Research subject. The Nenya-Chumysh basin is a long-term Mesozoic intracontinental sedimentary basin confined to the zone of a regional fault separating the Salair from the structures of Gorny Altai, Gornaya Shoria, and the Kuznetsk basin. Aim. To establish the geological and structural-kinematic characteristics of impulses of intracontinental orogeny that took place during the Mesozoic and Cenozoic in the territory of the northwestern part of the Altai-Sayan Folded Area. Materials and Methods. Geological maps of the area, geophysical data on the position of the base of the Paleozoic basement, satellite images and digital elevation models were used. The sedimentary filling of the basin is considered as a chronicle of tectonic movements in the NW part of the Altai-Sayan Folded Area at the intracontinental stage of development. Results. The Early Jurassic, Early Cretaceous, Late Cretaceous-Paleogene, and Neogene-Quaternary tectonic stages of the development of the Nenya-Chumysh basin were distinguished. In the Early Jurassic, the Nenya-Chumysh basin was a pull-apart basin in a left-hand strike-slip zone. This stage is associated with the accumulation of coal-bearing deposits of the Glushinskaya Formation, the thickness of which in the Nenya-Chumysh basin reaches about 1900 m. In the Early Cretaceous, as a result of changes in the stress field, the Nenya-Chumysh basin was transformed into a thrust basin, composed of terrigenous deposits of the Ilek Formation, forming a wedge-shaped sedimentary basin characteristic of foreland troughs. The neotectonic structure of the Nenya-Chumysh basin, formed in the stress field of the Indo-Eurasian collision, inherits an older structural plan in general terms, although differing in details. A non-inherited structure is the transverse neotectonic uplift of the Sary-Chumysh swell. Conclusions. The Early Jurassic stage is related with the closure of the Paleo-Tethys and the collision of a series of Cimmerian terranes with the southern margin of Eurasia, Early Cretaceous stage is caused with Mongol-Okhotsk collision, and the Cenozoic stage proceeds with the ongoing Indo-Eurasian collision. The geological evolution of continental sedimentary basins controlled by regional faults can be used as a source of information about the intensity and kinematic pattern of impulses of intracontinental orogeny in the geological past.

MINERALOGY OF THE ALLOWER GOLD DEPOSIT OF THE R. ZASLONKA (GORNAYA SHORIIA)

Geo Аssets Engineering, 2023, vol. 334, no. 5, рр.129-137. In Rus. The relevance of the work is caused by the need to replenish the mineral resource base of gold on the basis of comprehensive information obtained recently using a modern analytical base. Purpose: to study the mineralogical composition of samples of the placer deposit of the river Zaslonka (Gornaya Shoria). Methods: mineralogical studies, crystal morphology, X-ray spectral analysis, scanning electron microscopy. Object: samples of concentrates from the alluvial gold deposit of the Zaslonka river (Gornaya Shoria). Results. The authors carried out the study of the mineralogical composition, including the morphology of gold particles, samples of black concentrates on the MBS-10 binocular microscope and OLYMPUS SZX10 stereomicroscope, and slags after gold melting during the preparation of doré alloy on a Hitachi S-3400N scanning electron microscope. Photomicrographs of various types of gold particles and other minerals were taken. As a result of the research, it was found that the vast majority of gold particles belong to very small (68,71 %), as well as to small (14,69 %) and thin (12,47 %) size classes. Gold concentrates, after enrichment on a flotation table, are weakly radioactive due, apparently, to a thin dissemination of Th-U-containing minerals, which is confirmed by the study of slags on an electron microscope after melting gold during the production of doré alloy, where uranothorite, zircon and gold are found in the form of granular spherules. There are, apparently, three sources of gold entering the placer: 1) gold in the «shirt», covered with dark gray, almost black dense films, which is older gold and probably has a more distant source of drift; 2) gold of medium degree of roundness – flattened and lumpy golden-, dull-yellow and silvery-yellow in color, the sources of formation of which were medium-temperature and medium-distant quartz veins of the area; 3) unrounded golden-yellow gold, formed from nearby quartz weakly gold-bearing veins. The poor mineralogical composition of concentrates (and the almost absence of oxidized sulfide minerals, except for pyrite) indicates the presence of low-sulfide medium-temperature quartz veins with a low content of fine gold in primary ores.

Salair–Gornaya Shoria Junction (Northwestern Central Asian Orogenic Belt): Deep Structure and Tectonics from Magnetotelluric Data

Abstract —The Salair fold-thrust orogenic belt (Salair orogen, Salair) is located in the northwestern Altai–Sayan fold area within the Central Asian Orogenic Belt. The Salair orogen is an allochthon overriding the Kuznetsk Basin on a system of imbricate thrusts. The southern flank of the Salair thrust system is tectonically juxtaposed against the Gornaya Shoria terrane which differs markedly from Salair in its geological setting. The Salair and Gornaya Shoria terranes are separated by the Nenya-Chumysh Basin, a deep Mesozoic trough. The Salair orogen is composed of Cambrian–Early Ordovician island arc volcanic and sedimentary rocks, widespread garnet amphibolites and gneisses of the Angurep complex in its southern flank, and the Shalap subduction-related melange in the Alambai ophiolite suture. The southern Salair orogen and its junction with Gornaya Shoria have been imaged down to the lower crust by magnetotelluric (MT) soundings, which is an efficient tool for investigating the deep structure and tectonic history of orogenic areas. The MT surveys were performed at 25 stations on a 120 km long profile. MT data revealed an up to 70 km wide low-resistivity zone (a conductor) traceable till a depth of 20 km between the Salair and Gornaya Shoria terranes. The low-resistivity zone has a complex structure with its outer and interior boundaries dipping almost vertically. The conductor lies under several major geological structures: the Shalap melange, the Nenya-Chumysh Basin, and the NE trending Altai–Salair right-lateral strike-slip fault. The Altai–Salair fault, along which the Salair allochthon was displaced relative to Gorny Altai and Gornaya Shoria, joins the Salair system of imbricate thrusts. The Nenya-Chumysh Basin at the Salair–Gornaya Shoria junction is a deep trough having an asymmetric transversal profile with a steep western side and a shallower-dipping stepped eastern side. The southeastern flank of the basin is a wide area of thin sediments over the Paleozoic basement dipping gently in the northwestern direction. The revealed deep structure of the Nenya-Chumysh trough is consistent with its tectonic model implying an Early Cretaceous basin superposed over an early Jurassic pull-apart basin. Early Mesozoic motions on major faults is a regional-scale phenomenon known from many areas of southern West Siberia.

Stability of ore chutes in block caving

The geomechanical focus of the research presented in the article is mainly due to a number of problems that the iron ore mines in Gornaya Shoria face with an increase in the depth of mining. The high natural tectonic stress state of the ore province imposes certain restrictions on the technology and parameters of mineral extraction. The mining system now in use, with blasting and multi-point ore drawing under overlying rock mass using vibrating-and-hauling facilities is a structurally complex technology. It imposes severe requirements on the stability of outlets in the bottom of extraction blocks. One of the main disadvantages of block caving with ore drawing from the bottoms of the extraction blocks is the increased indentation of the block bottom with various-purpose openings. This circumstance prompts the search for new engineering solutions, including the revision of existing ones, to enhance the safety of ore production. To this effect, the mining practices undertake scientific substantiation of measures and recommendations for safe mining operations. In the article, on the basis of mathematical and physical modeling of the stress state of rock mass, the geomechanical assessment of the stability of the outlets in the bottom of the extraction block is given. It is revealed that the technology with massive block caving in rather difficult conditions of the geodynamic stress field and at the great depth of mining, with the accepted design parameters, becomes unsafe and is accompanied by both the loss of stability of rocks and the increased number of ore arching events in ore chutes. Therefore, identification of potentially hazardous places in the structural elements of the mining system, where accidents are possible, is a very popular technique in mine support design.

НОВЫЕ МАТЕРИАЛЫ ПО АРХЕОЛОГИИ ГОРНОЙ ШОРИИ

The article publishes and examines an archaeological collection of seven fragments of ceramic dishes, found in 2022 in the Kriminalnaya cave, which is located on the territory of Gornaya Shoria in the upper reaches of the Mrassu river. Archaeological objects were found in one cluster with animal bones and the remains of a fire pit near the entrance to the cave and probably make up a single cultural and chronological complex of finds of human life. Fragments of ceramic utensils, of which four were ornamented and two were corollas, probably belonged to three vessels. According to the results of comparing the described elements and motifs of ornamentation of fragments of the collection of ceramic dishes, a preliminary conclusion was made that these finds can be attributed to the circle of post-Andronian cultures of the transition from developed to late bronze.

The role of clinical and genetic factors in the progression of hypertrophy of the left ventricular myocardial in arterial hypertension

Introduction. A special position among the structural changes of the heart is occupied by left ventricular myocardial hypertrophy (LVH), which refers to the subclinical signs of heart damage in arterial hypertension (AH). Currently, the role of not only demographic, neuroendocrine, but also genetic factors in the development and progression of LVH is no longer in doubt.Aim. To assess the role of clinical and genetic factors in the progression of LVH in patients with hypertension based on the results of a dynamic 5-year follow-up of a cohort of Shors.Materials and methods. The survey of the indigenous population in Gornaya Shoria was carried out in two time periods: onetime (from 2013 to 2017) and prospective (from 2018 to 2020). The study included the adult population (18 years and older) – a total of 901 people – by continuous method. A group of patients with hypertension was identified – 367 people (40.7%). LVH was assessed by electrocardiography and/or echocardiography. The prospective stage of the study included patients with hypertension who had not previously received antihypertensive therapy (263 people). The control and correction of blood pressure numbers was carried out annually, the dynamics of LVH was assessed after five years.Results. Clinical predictors of negative dynamics of LVH were established: obesity (OR = 3.61), abdominal obesity (OR = 4.11), impaired carbohydrate metabolism (OR = 2.83), low high-density lipoprotein cholesterol (OR = 2.05). Genetic markers also demonstrated their involvement in the progression of LVH: allele D of the ACE gene, allele C of the AGTR1 gene, and 4a of the eNOS gene (OR = 9.69; OR = 6.72; OR = 6.37, respectively).Conclusion. The associations of clinical and genetic factors with LVH identified in the Shor cohort can be considered as predictors of myocardial remodeling in hypertension. The data obtained support the hypothesis that polymorphisms of the renin-angiotensin-aldosterone system and endothelial function can influence the phenotype, creating new approaches to the possible prediction of unfavorable outcomes.

Justification of stability strategy for underground mine openings under higher effective anisotropic stresses

Stability of underground openings is one of the critical challenges in the mining industry. A mine support system design and installation depends on the conditions of mining. This is especially pronounced in the regions of active tectonics with horizontal stresses higher than vertical stresses up to 2–5 times. The tectonic stress-induced activity accompanies even comparatively shallow mining operations. Dense fracturing, spalling and bursting are observed in mines in Gornaya Shoria, or in Apatit JSC mines, at the depths of 150 to 400 m in Russia, at the depth of 260–400 m in uranium mines in Canada, 250 m in Tirol in Austria, or 100–200 m in Norway. As a result of the accomplished studies, the mechanism of fracture zones in adjacent rock mass during heading and mining in high-stress rock mass is defined. The parameters of these zones are determined subject to the rock mass quality, structure and stress–strain behavior. This allows developing the heading technology and mine support system design for the conditions of higher tectonic stresses. The main transient factors capable to affect underground openings are identified, and it is shown that the technology of heading and mine support under dynamic events caused by rock pressure depends on such determinants as: the quality of fragmentation by blasting, blasting sequence, temporary and permanent support designs and lag of the mine support behind the face advance. The proposed approach to the underground mine stability under higher effective anisotropic stresses ensures safe mining at optimal rates of heading.

Echocardiography indices in urbanized representatives of the Shor ethnic group with the presence of arterial hypertension

Abstract In patients with arterial hypertension, the detection of left ventricular hypertrophy has important clinical and prognostic significance. The use of published regulatory “control limits” remains limited and cannot be extended to other racial and ethnic groups. The aim of this study was to compare echocardiography indicators in patients with arterial hypertension from two ethnic groups living in the Gornaya Shoria region. Methods The study included patients with arterial hypertension: 58 indigenous and 50 non-indigenous urbanized residents, comparable in age, and divided by ethnicity and gender into 4 groups: men of indigenous nationality (n=20), women of indigenous nationality (n=38), men of non-indigenous nationality (n=15) and women of non-indigenous nationality (n=35). All of them underwent echocardiographic examination. Results The body weight and BSA were lower in men and women of Shor ethnicity than in men and women of non-indigenous ethnicity (p=0.0014 and p=0.004). LAi was significantly larger in men of Shor nationality (p=0.049), at the same time, the size of their RA was the smallest (p=0.04). The data of the longitudinal LV systolic function in the form of a systolic excursion of the septum (s'sept) were the highest in Shor men (p=0.004), and the LV performance index was the lowest in them (p=0.012). Also in this group, the minimum isovolumic relaxation time (p=0.03) and the highest rate of early diastolic filling of the LV (p=0.04) were noted. When assessing correlations independent factors associated with pronounced LVH were glucose, DBP, and urea in Shor patients. Non-indigenous nationality independent factors associated with pronounced LVH were waist circumference and DBP. Conclusion Echocardiographic examination of patients with hypertension revealed the features of structural and functional indicators in the representatives of the indigenous urbanized population of the Mountain Shoria in comparison with the representatives of the non-indigenous population. This study can be useful in assessing the impact of the development of arterial hypertension, as well as the impact of changing the lifestyle of the Shors when moving to the city from rural areas on ethnic differences in echocardiography.

ИССЛЕДОВАНИЕ РАЗВИТИЯ КОНТУРА ПРОВАЛА В РАЙОНЕ ГОРЫ БУЛАНЖЕ

The relevance of the study is to develop a methodology for monitoring manufacturing objects us-ing unmanned aerial vehicles formed as a result of mining operations. The Tashtagol iron ore deposit is located in the south of the Kemerovo region in Gornaya Shoria, and is being worked underground. The development of the reserves of the South-Eastern section has been carried out since 2004 by the Tashtagol branch of company Evrazruda. A special feature of the South-Eastern section reserves min-ing is the operation of protected objects within the zone of potential hazardous displacements, as a re-sult of which, presumably in November 2017, a sinkhole was formed in the area of Mount Boulanger. The aim of the work is to describe the method of monitoring the determination of the geometric dimensions of the sinkhole in different periods of time using an unmanned aerial vehicle. The sinkhole development has been monitored since 2018. As a result, this study determines the geometric dimensions of the sinkhole in different periods of obser-vations, and calculates the average sinkhole increase dynamics of the per year.

Выделение психрофильных микроорганизмов из природных источников Кемеровской области и изучение их антимикробных свойств

Introduction. Extreme psychrophiles still remain largely understudied. However, they can serve as biological components in drug production, as well as increase the shelf life of food products in food industry. Therefore, the properties of psychrophilic microorganisms are a relevant study object. The present research objective was to isolate new psychrophilic microorganisms in extreme low-temperature conditions of the caves of Gornaya Shoria and Salair (Kemerovo region) and study their antimicrobial properties.
 Study objects and methods. The research featured psychrophilic microorganisms isolated in the caves of the Kemerovo region. The sampling was performed in triplicate. The samples were placed in sterile paper. Antibiotic resistance was defined according to the area where the antibiotic plate suppressed bacterial growth. The cell suspension was placed in a Petri dish with an agar-based medium. The discs with antibiotics were put on the surface of the medium and incubated in a thermostat at 28°C for 24 h in order to describe the growth of the isolates.
 Results and discussion. The microbial communities of the Gavrilovskaya and Azasskaya caves produced seven isolates with different morphological characteristics. Isolates 1, 4, and 5 had pronounced suppressive properties at 2 ± 4°C. Isolates 1, 4, and 5 proved resistant to antibiotics. Isolate 1 exhibited high resistance (21–26) to Neomycin and Novogramon, medium resistance (17–22) to Ceparin, Kanamycin, Levomycin, Carbenicillin, and Streptomycin, and low (2–8) resistance to Benzylpenicillin and Clotrimazole. Isolate 1 had no antibiotic resistance to Ampicillin, Gentamicin, and Tetracycline. Isolate 4 showed high resistance (22–27) to Novogramon, medium resistance (10–22) to Tetracycline, Clotrimazole, Neomycin, Zeparin, Kanamycin, Levomycin, and Monomycin, and low resistance (2–8) to Ampicillin, Benzylpenicillin, Streptomycin, and Gentamicin. Isolate 4 demonstrated no antibiotic resistance to Carbenicillin and Polymyxin. Isolate 5 proved highly resistant (27–26) to Ceparin, Benzylpenicillin, Levomycetin, and Novogramon, and medium resistant (12–22) to Clotrimazole, Streptomycin, Neomycin, Gentamicin, Polymyxin, Carbenicillin, and Monomycin. Isolate 5 demonstrated no resistance to Ampicillin, Tetracycline, and Kanamycin.
 Conclusion. Psychrophiles can serve as microorganisms to create new biological products that suppress the development of diseases in plants. Psychrophiles proved an extremely promising research direction for cultivating and storing agricultural products.

Transport Culture of the Population of Gornaya Shoria in the Early 20th Century Based on Photographs by G.I. Ivanov

The publication analyzes a collection of photographs by Grigory Ivanovich Ivanov (1876-1930), which is kept in the Altai State Museum of Local Lore in the city of Barnaul. The photographs were taken by Ivanov in 1913 during his expedition to the remote areas of Gornaya Shoria. The introduction of these photographs into scientific circulation became possible only at the end of the 20th century. The photographs show the traditional culture of the indigenous inhabitants of this area - the Shors, who at the time of Ivanov's expedition still retained the traditional features of their ethnic culture. The photographs show the traditional material culture of the Shors, their traditional means of transportation and transport. The most developed among the Shors at that time were winter means of transportation and transport (skis, sledges, scraps), which ensured hunting. Water vehicles (boats, rafts, ferries), which made it possible to move people and goods along mountain rivers were equally important. In the early 20th century horses were used by the Shors for horseback riding, as well as for horse and goose transport of goods. The horse equipment used in this case was distinguished by great archaism. In remote mountainous areas, the local population also used archaic methods of transporting goods by hand. However, the photographs also show more developed forms of vehicles and transport, which the population of Gornaya Shoria began to use in the early 20th century under the influence of the Russian population.

Design of Support Systems for Rockburst-Hazardous Underground Mines in Gornaya Shoria

The influence of jointing on the stability of adjacent rock mass is analyzed using the coefficient of structural weakening and the joint spacing. The gravity–tectonic stress field of ore bodies in Gornaya Shoria, including the azimuth of the principal horizontal stresses is characterized. The laboratory tension tests of combinations of support systems as well as the small-scale extension tests of rock bolts made of different materials are discussed. The framework for a multi-factor digital model of safe and efficient support design for iron ore mines in Gornaya Shoria is based on the stability assessment of adjacent rock mass in terms of jointing and stress state.

Genetic forms and pathophysiology of essential arterial hypertension in minor indigenous peoples of Russia

BackgroundTo study the genetic forms and pathophysiology of arterial hypertension by evaluating plasma renin activity in the Shors, minor indigenous peoples inhabiting the south of Western Siberia.MethodsA single-stage study of indigenous (the Shors) and non-indigenous peoples living in the villages of Gornaya Shoria of the Kemerovo region in the south of Western Siberia was conducted in the period from 2013 to 2017. One thousand four hundred nine adults (901 Shors and 508 non-indigenous inhabitants) were recruited in the study using a continuous sampling plan. Arterial blood pressure was measured according to 2018 ESC/ESH guidelines for the management of arterial hypertension. All the respondents underwent clinical and instrumental examination. Plasma renin activity was determined by enzyme-linked immunoassay with the BRG kits (Germany). Polymorphisms of ACE (I/D, rs 4340), АGT (c.803 T > C, rs699), AGTR1 (А1166С, rs5186), ADRB1 (с.145A > G, Ser49Gly, rs1801252) and ADRA2B (I/D, rs 28,365,031) genes were tested using polymerase chain reaction.ResultsRenin-dependent hypertensive patients prevailed in both ethnic groups (65.6% in the indigenous group vs. 89.8% in the non-indigenous group, p = 0.001). Prevalence of a volume-dependent AH was low in both groups (34.4% in the indigenous group vs. 10.2% in the non-indigenous group, р = 0.001). The D/D and Т/Т genotypes of the АСЕ [OR = 6.97; 95% CI (1.07–55.58)] and AGT [OR = 3.53; 95% CI (1.02–12.91)] genes were associated with the renin-dependent AH in the Shors. The C/C genotype of AGTR1 gene was found to predispose to the volume-dependent AH [OR = 5.25; 95% CI (1.03–27.89)]. The C/C genotype of AGTR1 gene was associated with moderate or high renin levels suggesting essential AH in the non-indigenous group [OR = 5.00; 95% CI (1.21–22.30), р = 0.029].ConclusionAn in-depth understanding of AH pathophysiology and its genetic forms ensures the optimal choice of blood pressure-lowering treatment and optimizes AH control.

Prevalence of coronary artery disease in the indigenous population of Gornaya Shoria (the results of epidemiological studies in 1998-2001 and 2013-2017)

Aim. To study the features of the prevalence of coronary heart disease (CHD) in the period 1998–2001 and 2013–2017 in the indigenous population of Gornaya Shoria.Methods. In the first period of the study (from 1998 to 2001), 550 respondents of indigenous nationality living in rural areas of Gornaya Shoria (v. Orton and v. Ust-Kabyrza) were included. In the second period (from 2013 to 2017) – 937 people in the same villages, as well as in the urban village Sheregesh and city Tashtagol. The presence of coronary artery disease was estimated by the sum of three epidemiological criteria: based on the analysis of ECG by Minnesota code, Rose questionnaire and a history of myocardial infarction. Statistical analysis was performed using the program Statistica 6.0 (StatSoft Inc., USA.) Qualitative features were described using frequencies as a percentage. To determine the statistical significance of these differences, Pearson's criterion c2 was evaluated. In the study, the critical level of significance when testing statistical hypotheses was taken p<0.05.Results. The frequency of CHD in the first stage of the study in the village was 6.2%, in the survey of the rural population in the Gornaya Shoria in 2013–2017 this figure was 8.0%. Comparative analysis at the second stage of the study showed a higher prevalence of this disease among urban residents (12.6%) compared with rural (8.0%, p = 0.048). These differences reach statistical significance due to the female population in the age groups of 40–49 years and 50–59 years (7.1% vs. 0% (p = 0.051) and 15.4% vs. 4.1% (p = 0.031)). In males living in the city, revealed an earlier debut of CHD in 40–49 years (5.6%).Conclusion. The study revealed an increase in the prevalence of CHD in women in the indigenous small population of Gornaya Shoria from 1998–2001 to 2013–2017, as well as a number of significant statistically significant differences in the frequency of CHD among the urban and rural population.

Support Design for Rockburst-Hazardous Underground Mines in Gornaya Shoria

Support Design for Rockburst-Hazardous Underground Mines in Gornaya Shoria

МИНЕРАЛОГИЧЕСКИЕ ОСОБЕННОСТИ РУД КАЛАРСКОГО ПРОЯВЛЕНИЯ И ВОЗМОЖНОСТИ ИОННО-СОРБЦИОННОГО МЕТОДА ДЛЯ ПОИСКА ПЕРЕКРЫТОГО ЗОЛОТО-СЕРЕБРЯНОГО ОРУДЕНЕНИЯ В АЛТАЕ-САЯНСКОЙ СКЛАДЧАТОЙ ОБЛАСТИ

The article presents results of studying the epithermal gold-silver mineralization of the Kalar occurrence of the Kaburchak ore cluster in the Mountainous Shoria (Gornaya Shoria). The Kalar occurrence is confined to metasomatites of berezite and argillisite composition. They contain veined and veinlet-disseminated zones of quartz-sulphide composition. The characteristic feature of the Kalar occurrence is the wide distribution of ore minerals – usually 5–10%, oft en up to 20%, and in some cases up to 60–70%, and their great variety. Ore minerals are represented mainly by pyrite, arsenopyrite, sphalerite, galena, chalcopyrite, fahlores, gold, as well as by Pb, Bi, Ag sulfides and Au, Ag, Pb tellurides. The results of experimental and methodological works within the Kalar occurence showed a high efficiency of using the ion-sorption method of prospecting developed at the Federal State Budgetary Institution (FSBI) TsNIGRI in conditions of high thickness of loose overlapping deposits. The ion-sorption survey carried out within the Kalar area made it possible to reveal secondary superimposed halos of dispersion of As, Sb, Ag, Pb, Zn, Cd, Cu, Ni, Co. The use of the ion-sorption method on the northern flank of the Kalar ore field, where overlapping Quaternary deposits up to 25 m thick are widely developed, made it possible to reveal a complex geochemical anomaly (Ag, As, Cu, Pb, Zn), which presumably reflects the northern continuation of the Central gold-bearing zone.

Трудовое использование заключенных в Южнокузбасском исправительно-трудовом лагере МВД СССР (1947–1950 годы)

The article considers the issues of use of prison labour in the “Southern Kuzbass Corrective Labor Camp of the USSR Ministry of Internal Affairs”. The chronological framework of the study is set between 1947 and 1950. The camp was located in the south of the Kemerovo region in the Gornaya Shoria district. The Southern Kuzbass Corrective Labor Camp was established according to the resolution no. 409 of the Council of Ministers from March 1, 1947. The main activity of the camp was logging. However the penal labor was used not only in the logging industry, but also in the timber processing, construction, and agricultural sectors. Based on archival documents, this article shows the features of the organization of labor activity of prisoners, working conditions, methods of stimulation and encouragement. The author explains challenges that were faced in the process of implementation of measures aimed to improve the working and living conditions of prisoners, their general physical condition and their work motivation. Among them there were difficulties in carrying out measures for labor protection, calculation of wages for prisoners, determination of their employment category, use of mechanized equipment in production activities, ensuring satisfactory sanitary and living conditions. Despite this, the analysis of indicators of labor productivity for individual logging phases in the camp demonstrates a positive trend.

Features of seasonal migrations and wintering of epy elks (Alces alces) in the Kuznetsk-Salair mountain region

The article presents an analysis of elksэ seasonal migrations in the Kuznetsk-Salair mountain region, where a largely independent population of the species has developed. Its core is located in the administrative boundaries of the Kemerovo region. In snowless and little snow periods, elks are diffusely located in forest areas of the region. In the Kuznetsk-Salair mountain region, seasonal migrations of moose are caused by the need to move from the snowy slopes and foothills of the Kuznetsky Alatau, the Gornaya Shoria, and the Salairsky ridge to the little snowy slopes of the eastern exposition, to the steppe and forest-steppe parts of the Kuznetsk Basin and the Mariinsky-Tisulsky forest-steppe areas. In some places, these migrations are cross-border in nature, affecting the administrative territories of the Altai and Krasnoyarsk Regions, the Republics of the Gorny Altai and Khakassia, and the Novosibirsk and Tomsk Regions. After the depression of the beginning of the last century, up to 24 winter camps were formed when the elk reappeared on the territory of the Kemerovo region (Kuzbass). Local animals from the Kuznetsk Alatau and Gornaya Shoria and animals from the adjacent areas of the Altai, Novosibirsk, and Tomsk regions migrated regularly to these sites. At the same time, a part of elks from the Kuzbass southern regions migrated to the territory of Altai and Khakassia. In the 1960s and 1980s, the elk winter sites were clearly localized, up to 300-500 animals were concentrated in the largest of them. In the Kemerovo region, a system of regional specially protected natural areas (SPNA) was created. In the 1990s, in the period of the decline in the number of elks, about 15 winter sites remained. And since the 2000s, many wintering sites have become diffuse, seasonal migrations have changed. Currently, with the exception of 4 large sites, in the Kuznetsk Basin, most elks do overwinter in small herds from 2-3 to 20-30 head. They are dispersed in forest areas with low snow cover, well protected or difficult to access for snowmobile transport.

Micrometric Inclusions in Platinum-Group Minerals from Gornaya Shoria, Southern Siberia, Russia: Problems and Genetic Significance

Micrometric inclusions in platinum-group minerals (PGMs) from alluvial placers carry considerable information about types of primary rocks and ores, as well as conditions of their formation and alteration. In the present contribution, we attempt to show, with concrete examples, the significance of the data on the composition and morphology of micrometric inclusions to genetic interpretations. The PGM grains from alluvial placers of the Gornaya Shoria region (Siberia, Russia) were used as the subject of our investigation. In order to determine the chemical composition of such ultrafine inclusions, high-resolution analytical methods are needed. We compare the results acquired by wavelength-dispersive spectrometry (WDS; electron microprobe) and energy-dispersive spectrometry (EDS) and scanning electron microscopy (SEM) methods. The results obtained have good convergence. The EDS method is multi-elemental and more effective for mineral diagnostics in comparison with WDS, which is its certain advantage. The possible conditions for the formation of inclusions and layers of gold, sulfoarsenides and arsenides in Pt3Fe grains, which have an original sub-graphic and layered texture pattern, are discussed. They are the result of solid solution and eutectic decompositions and are associated with the magmatic stages of grain transformation, including the result of the interaction of Pt3Fe with a sulfide melt enriched with Te and As.

STRUCTURAL AND FUNCTIONAL INDICATORS OF ECHOCARDIOGRAPHY IN HEALTHY REPRESENTATIVES OF INDIGENOUS AND NON-ORGANIZED URBANIZED POPULATION OF GORNAYA SHORIA

Aim: To study the structural and functional parameters of echocardiography in healthy representatives of the urban Shor population, including men and women.Material and Methods. The study included 96 indigenous and 66 non-indigenous urbanized residents of Gornaya Shoria, matched by age and divided according to ethnic and gender characteristics into 4 groups: indigenous men (n=40), indigenous women (n=56), non-indigenous men (n=32), and non-indigenous women (n=34). All individuals underwent echocardiographic study. Body surface area-indexed left and right heart structural parameters, pulse wave Doppler data, data on propagation atrioventricular flow rates, and spectral Doppler tissue data were studied.Results. According to the results of anthropometry, men and women of Shor nationality had a lower body mass and body surface area compared with the corresponding values in men and women of non-indigenous nationality (p<0.0001 in all cases). However, the indices of the thickness of the interventricular septum, the posterior wall of the left ventricle, left ventricular mass and stroke volume, the diameter of the aorta, and the anterior-posterior dimension of the right ventricle were significantly higher in the group of indigenous women compared to non-indigenous ethnic groups. (p<0.01 in all cases). The values of the left ventricular end-diastolic volume, left atrial volume, pulmonary artery diameter were significantly higher in both men and women of indigenous nationality relative to the corresponding female and male comparison groups (p<0.01 in both cases). The tricuspid flow propagation velocity in male Shors was significantly higher than that in non-indigenous men (p<0.01). The Shor nationality was associated with a decrease in body surface area and increases in aortic diameter indices, pulmonary artery, left ventricular posterior wall, left ventricular myocardial mass index, pulmonary artery index, right atrial area index, and tricuspid flow propagation velocity; only a decrease in body surface area was associated with the female sex.Conclusion. In healthy representatives of the indigenous population of Gornaya Shoria, ethnic differences in the structural and functional parameters of echocardiography prevailed over gender-related differences.
