A high variability of landslide density and distribution was observed in the western part of the Słonne Góry (Sanok region, Eastern Carpathians, SE Poland). A statistical method, the bivariate Frequency Ratio Model (FRM), was used to show the reasons for this variability and to compile a map of landslide susceptibility for the study area. The landslide susceptibility map was calculated using an inventory of previous landslides and using buffer zones mapped around the upper parts of landslides. The polygons of landslides represented disturbed features and slope properties. In contrast, buffer zones represented undisturbed slope features and properties. Both methods gave similar results. Two landslide susceptibility maps were obtained with the following Area Under the Curve (AUC) values: 0.7936 for landslides and 0.7971 for buffer zones. This indicates a sufficiently good fit of the computational models for predicting new landslides. Unfortunately, the use of buffer zones in the calculations, which represent undisturbed slope properties, did not improve the predictive values of the susceptibility maps. Significant differences were shown as regards slope angle. The importance of this parameter (slope angle) for the Polish part of the Carpathians was better enhanced by the use of buffer zones in the landslide susceptibility calculations

The Dawenkou Basin in China is a significant Cenozoic evaporite basin containing a diverse range of salt minerals, including halite, anhydrite, glauberite, polyhalite, and various Na-Mg and K-Mg salts. This study investigates the origins of brines that contributed to salt formation in the basin, as well as the sedimentary and post-sedimentary mineralization processes, through fluid inclusion analysis in halite and sulphur-oxygen isotopic studies in anhydrite. Analysis of fluid inclusions in halite from well XZK 101 revealed both primary and secondary inclusions, with evidence of tectonic activity, recrystallization, and fluid migration. Brine compositions vary widely, with K+, Mg+, and concentrations indicating multiple stages of mineral formation and alteration. The presence of hydrocarbons and algal remnants in inclusions suggests interactions with organic material during or after salt deposition. Isotopic data (δ³⁴S and δ¹⁸O) from anhydrite show values suggesting the primary sulphate source was leached from Cambrian and Ordovician evaporites in the surrounding Yi-Meng Mountains, rather than solely from marine sources. The chemical and isotopic composition of the brines does not exclude the influence of marine transgressions during the Eocene, although the dominant input of sulphate appears to come from continental sources. The complex interplay between marine influx, tectonic processes, and continental sulphate leaching shaped the unique salt mineral assemblage observed in the basin today

We describe a high-resolution analysis of subfossil Cladocera conducted at the Lugi site in Poland, a peatland ecosystem that developed within a former lake in the Warta River Valley. Study focused on core sections corresponding to periods of rapid climatic change during the Late Glacial/Holocene transition, enabling detailed observation of environmental transformations. Palynological analysis facilitated the determination of boundaries between cold and warm periods. The Cladocera analysis revealed that, during the end of Oldest Dryas, the lake was shallow with conditions unfavourable for Cladocera development. At the onset of the Bølling period, warming led to increased species diversity and a rise in water levels within the lake. Following this warming and associated ecological changes, the Bølling-Allerød period was characterized by continued progressive warming, that was interrupted by the Older Dryas cooling event, marked by a sharp decline in Cladocera species. At the end of the Allerød, there was a decline in lake water levels, followed by the onset of the Younger Dryas, which brought a notable cooling trend. The Younger Dryas/Holocene transition was not captured due to a hiatus in sediment deposition. Data from the sediment section corresponding to the Holocene (Boreal period) revealed improved habitat conditions and a warming of the waters. These analyses and interpretations are aimed at comparing records of rapid climatic changes as recorded by Cladocera remains, and demonstrating differences in their course in basins that differ from each other as regards habitat features.

A three-dimensional geomagnetic model of the Myutenbay deposit has, been created in the Geosoft Oasis Montaj program, based on digital modelling of magnetic exploration data previously carried out at the site, and using the petrophysical characteristics of the ore-bearing rocks. A three-dimensional model of the ore bodies was created in Micromine software using information from boreholes obtained during the exploration stage of the deposit. The shape of the ore bodies and that of the three-dimensional magnetically disturbing objects in the geomagnetic model were established as identical. A two-dimensional geomagnetic model clearly shows the fault zone, the folded rocks of the Murun suite and the orientation of the ore bodies within the Kosmanachi ore-bearing strata. The mapped magnetic anomalies reflect zones of progressive regional metamorphism, which collectively determined the location of gold ore mineralization. Zones of correlatable magnetic maxima reflect the development of pyrite-pyrrhotite vein-disseminated mineralization, related to areas of gold-producing ore body.
