Socio-Economic and Gender Dynamics in Indo-Bangladesh Border Enclaves: Challenges and Opportunities

This paper intends to explores the unique socio-political, economic, and gender dynamics in the Indo-Bangladesh border enclaves. It delves into the historical background of enclave formation, the legal status of enclave residents, the economic conditions and livelihood opportunities available to them, traditional gender roles, and the barriers that exist to socio-economic empowerment. The analysis identifies key challenges faced by enclave residents while also shedding light on potential opportunities for improving their living conditions.

Nucleation delay controlling the formation of mafic enclaves and banded pumice

The presence of mafic enclaves and banded pumice reveals key physical processes associated with volcanic eruptions. Here, through the textural and geochemical analyses of the 3550 B.P. Waimihia deposits in Taupō, New Zealand, we demonstrate how disequilibrium crystallization controls the way magmas mix. Andesitic enclaves in pyroclastic deposits from this predominantly rhyolitic eruption consist of microlites that crystallized rapidly during mafic injection into rhyolitic host magma. The variation of microlite textures depends on enclave size, implying that mafic enclaves crystallized as discrete blobs within a host rhyolitic magma. However, gray pumice and dark bands in banded pumice are characterized by a lack of or less plagioclase microlites that should be present if equilibrium crystallization occurred. Our textural and chemical data suggest that the lack of plagioclase in gray pumice and dark bands resulted from the nucleation delay arising from the mixing with rhyolitic magma. After mafic magma broke up in a magma chamber as discrete mafic blobs, the plagioclase-free rim of the blobs was disaggregated by shear flow. The eroded mafic blobs form a hybrid magma by mixing with rhyolitic magma, which further delays the plagioclase nucleation. This hybrid magma eventually erupted as gray pumice or banded pumice, depending on the intensity of magma mingling in the conduit. We use a plagioclase nucleation delay model to calculate residence times of hours to tens of hours prior to eruption. Our mixing model with nucleation delay enables small volumes of mafic magma to mix with large amounts of silicic magma.

Conditions for formation and preservation of andesite-hosted mafic enclaves during the 2018 Lower East Rift Zone eruption of Kīlauea

Andesites erupted at Kīlauea in 2018 in the Lower East Rift Zone for the first time in the known geological record. The evolved lavas erupted at Fissure 17 of the 2018 eruption, ranging from andesites to basaltic andesites, contain abundant mafic enclaves both in the lava flows and the ejecta, which are unusual at Kīlauea and in Hawai'i in general. Textural observations indicate that the enclaves originate from incomplete mixing of two magmas rather than the incorporation of cold basaltic wall rock. We suggest, on the basis of bulk and mineral compositions, that the source of the mafic enclaves is the early 2018 evolved basalt magma (phase 1b) that erupted concomitantly at adjacent fissures, which mixed with the andesite to produce the range of basaltic andesite compositions observed at Fissure 17. The coexistence of homogenized basaltic andesites and mafic enclaves within the same magma require a mixing mechanism resulting in both complete homogenization and preservation of enclaves. We propose that the range of mixing and mingling processes may be explained by spatial and temporal variability in the mixing percentages of the phase 1b basalt and the andesite within the andesite magma chamber. Field observations, chemical compositions, and 2D thermal conduction models suggest that enclaves are preserved where the basalt contribution to mixing is less than roughly 40 %, as a result of microlite crystallization leading to rigidification of the enclave magma. Above this threshold, the mixed magmas became largely homogenized. The scarcity of mafic enclaves at Kīlauea and in the Hawai'i igneous record is likely explained by mixing between magmas that lack sufficient compositional and rheological contrasts to preserve them.

Cognate Mafic Enclaves Formed by Cumulated Mush Convection in a Granitic Magma Chamber: Evidence from Mineral Chemistry of the Triassic Zhashui Pluton, Qinling Orogen

AbstractMafic enclaves in granites are generally considered to represent coeval mafic melts that derived from metasomatized mantle, which can provide valuable information about crust–mantle interaction. Exploring the genetic links between the mafic enclaves and their host monzogranite from the Triassic Zhashui Pluton, Qinling orogenic belt. The enclaves (220 ± 4.6 Ma) and the monzogranite (220 ± 2.8 Ma) display identical zircon U‐Pb ages, and they also share similar trace element and zircon Lu‐Hf isotopes, indicating a cognate source. The monzogranite displays zircon εHf(t) values of –0.99 to +1.98, while the mafic enclaves show similar values of –0.45 to +3.26; however, differences in mineral chemistry reveal different crystallization conditions. The amphibole from the mafic enclaves has higher temperature and pressure (757°C; 2.65 kbar) compared to those of the host monzogranite (733°C; 1.96 kbar), suggesting that mafic minerals in the enclaves crystallized at an early stage. Moreover, apatite in the mafic enclaves displays slightly higher volatile contents (0.72 wt%) than those of the monzogranite (0.66 wt%), indicating a volatile‐rich condition. These results suggest that the mafic enclaves represent early hydrous mafic cumulates in the granitic chamber, and subsequent magma convection would have led to the formation of the mafic enclaves.

THE HISTORICAL AND GEOGRAPHICAL LANDSCAPE OF MIGRATION TO RUSSIA FROM THE NEAR ABROAD IN THE LATE 20th AND EARLY 21st CENTURIES: A VIEW FROM WITHIN

Th e disintegration of the USSR in 1991 set off unprecedented migration processes across the post-Soviet space, remarkable for their scale and complexity. Th is multifaceted migration phenomenon, with its various forms and manifestations, highlights the crucial need for an interdisciplinary approach in studying the issue. Th e novelty and relevance of this work stem from its pioneering attempt to illustrate the dynamics of migration processes in post-Soviet Russia through the application of a broad range of methodologies from diff erent humanities disciplines. Th is article presents a portion of the fi ndings from a comprehensive study conducted by an interdisciplinary research team at Lomonosov Moscow State University. Th is team, which includes historians, geographers, psychologists, and lawyers, is part of the university’s development program project, “Interdisciplinary Study of Modern Migrations: New Analytical Approaches”. Th e authors conduct a comprehensive review of current literature on the geographical, demographic, historical, sociological, and anthropological aspects of migration. Th ey analyze thematic documents from the Ministry of Internal Aff airs of the Russian Federation and the Federal State Statistics Service, as well as archival materials covering the past 30 years, up to 2022. Th ese sources hold signifi cant academic value for research in the fi eld. Th e study identifi es the phases and intensity of migration dynamics in the Russian Federation and highlights key trends within the context of global and domestic factors, such as the economic crisis, the COVID-19 pandemic, and shift s in Russia’s current migration legislation. Th e article also explores the concept of ethnic enclaves and off ers a functional, operational, and interdisciplinary defi nition of this phenomenon. It traces and explains the causal relationships that lead to emerging points and nodes of tension, as well as the potential threats inherent in migration processes and enclave formation. Additionally, the study outlines historically driven changes in the dynamics, types, and demographic structure (gender and age) of migration fl ows to Russia, infl uenced by both external and internal developments within the country.

Модели противодействия сегрегации этноконфессиональных иммигрантских районов в Дании и Швеции

The article explores the immigration and integration strategies of Denmark and Sweden while assessing their efficacy. The two countries, sharing historical, cultural, social and economic similarities, face a common challenge: the formation of ethnoreligious enclaves primarily inhabited by individuals with a Muslim background. Due to the recent European migrant crises, there has been a notable increase in the number of migrants, leading to stricter integration policies in the Scandinavian countries. Yet, governmental approaches to address the segregation of immigrant areas vary between Denmark and Sweden. Denmark has adopted a stringent immigration policy promoting cultural assimilation of immigrants from non-Western countries, whilst Sweden follows a liberal approach advocating cultural and ethnic diversity within society. The evolution of immigration and integration initiatives in Denmark and Sweden has been reconstructed through the analysis of official documents and critical examination of political discourses. It is noted that Swedish authorities are increasingly incorporating Denmark’s more radical approaches to address migration issues within their political programmes. Despite the results of Denmark’s anti-immigration policies and the reduction in the number of segregated immigrant areas, a myriad of issues persist due to EU immigration policies. The problem of forging a new civic identity rooted in the linguistic, religious and cultural homogeneity of Danish society amidst its multiculturalism remains relevant. Thus, Sweden is formulating its own anti-segregation programme, taking into account both the successes and shortcomings of Danish immigration and integration policies. Another important conclusion is that these nations have started to pay special attention to ethnic and religious criteria when identifying ‘parallel societies’.

ПРОТИВОДЕЙСТВИЕ ФОРМИРОВАНИЮ ЭТНИЧЕСКИХ (ПОЛИЭТНИЧЕСКИХ) АНКЛАВОВ (АДМИНИСТРАТИВНО-ПРАВОВЫЕ АСПЕКТЫ)

The article deals with problem of ethnic enclave. This social phenomenon accompanies migration’s processes taking place in the modern word. The problem of formation of ethnic enclaves has been reflected in concept of state migration policy for 2019-2025 years. In 2023 this concept was correct-ed. Opposition to the formation of ethnic (poliethnic) enclaves received clearly expressed law enforcement orientation. The formation of ethnic (poliethnic) enclaves contributes to corruption factor, protectionist administrative measures, segregation and discrimination of migrants. The formation of ethnic enclaves is influenced by policy of the country receiving migrants. The importance of social and cultural adaptation of migrants but without their assimilation is emphasized. The key to success-ful counteraction of formation of ethnic (poliethnic) enclaves is combating illegal migration in combi-nation with flexible state migration policy which is based on combination of economic and administrative methods of regulation of migration processes.

A Note on the Definition of Ethnic Enclave

The author considers in detail the main approaches to the definition of ethnic enclave and enclavization. Taking into account the degree of elaboration of this problem due to the peculiarities of historical development, special attention is focused on the approaches reflected in foreign English-language publications on the economy of the enclave and social modeling. The author also addresses the problem of the formation of ethnic enclaves in the Russian Federation, acting as an obvious threat to public security. The methodological basis of the research is presented by the general dialectical method of scientific cognition. The prospects of enclavization are illustrated by official statistical data on the number of people registered for migration and who have received citizenship. Based on the analysis, it is concluded that the main features of an ethnic (polyethnic) enclave are the presence of a special economic structure and socio-cultural environment that exclude the processes of assimilation into society. In order to identify the enclave, it is advisable to use sociological methods (questionnaires, surveys of the local population) and a survey of the territory. Considering that migration processes are related to the determinants of crime, it is necessary to study the phenomenon of ethnic enclaves in a criminal aspect. Moreover, with the growth of external migration, the prospects of enclavization seem quite real. The negative consequences of enclavization are the growth of social exclusion, tension, an increase in crime, including migration and organized ethnic crime.

Consecutive underplating of cognate magmas: Contributions to the enclaves and large-volume plagiogranites in the North Qaidam orogen (NW China)

Magma mingling between mafic and felsic magmas is a plausible mechanism for the formation of mafic microgranular enclaves (MMEs) which are common worldwide. Through dissecting the MMEs with parentage of magma mingling, it can be ascertained how two types of magmas with contrasting physicochemical properties interplay and what implicit information magma mingling records in crust-mantle interaction. Here we present petrography, geochronology, major and trace elements, Sr-Nd-Hf isotopes, and mineral geochemistry for rock associations from the North Qaidam orogen, which provides new insights into the processes of magma mingling, petrogenesis of large-volume host plagiogranites and crust-mantle magmatic interaction. MORB (mid-ocean ridge basalt)-like and arc-like magmas can be distinguished from mantle-derived mafic samples with zircon UPb ages ranging from 480 to 465 Ma. MORB-like magmas originated from a MORB-type asthenospheric mantle, whereas arc-like magmas were derived from an ultra-depleted asthenospheric mantle as a result of consecutive extraction of MORB-like magmas and late-stage metasomatism by subduction-related aqueous fluids. Given the content discrepancies for major oxides, gabbro-dioritic MMEs are formed by incipient mechanical mingling between gabbro-diorite magmas and felsic plagiogranite magmas. MMEs and host plagiogranites yield coincident crystallization ages of 478 Ma and overlapped whole-rock SrNd ((87Sr/86Sr)i = 0.7044–0.7052; εNd(t) = +4.6 ∼ +5.6) and zircon Hf isotopes (εHf(t) = +13 ∼ +16). The host plagiogranite magmas are most likely derived by partial melting of pre-existing analogues of gabbro-diorite intrusions under the condition of consecutive underplating of different batches of cognate magmas over short time scales, which in turn determine the consistent isotope compositions between MMEs and host plagiogranites. As for mineral geochemistry, the plagioclases with the highest An% value and the hornblendes implying the highest melt water content, appear within the MME-bearing plagiogranites next to the chilled margin of MMEs, illustrating that aqueous fluid and heat transfer play a pioneering but finite role in incipient magma mingling. The consecutive underplating of cognate mantle-derived magmas as an ultimate engine leads to the partial melting of newly emplaced basites to form massive plagiogranite magmas and geochemically stratified crust. With magma ascent into a shallow level of crust, magma mingling between underplated mafic magmas and resultant plagiogranite magmas is finally realized.

Training for total devotion: emotionality and narrativity in Deuteronomy

ABSTRACT This article analyses ideals of total devotion in the Hebrew Bible, concentrating on the book of Deuteronomy. Understanding total devotion as an intense, emotional, and total relationship between a god and the worshippers, the analysis spotlights Deuteronomy 6–7, investigating emotion expressions used of the relation between the deity and Israel, their narrative embedding, and how narrativity stimulates and sustains emotions. I argue that the ideal of devotion involves a totality of scope, and – taking the broader affective and narrative economy into account – significant emotional intensity. The command to love is entangled in an emotionally intense elicitation of fear and disgust supporting enclave formation, identity fusion and costly sacrifice. Deuteronomy 1–11 can be understood as aiming to train devotion affectively and narratively. The analysis indicates that more attention should be paid to emotions, narrativity, and group-internal ideals of devotion in radical religion research.

“Upload Your Impact”: Can Digital Enclaves Enable Participation in Racialized Markets?

Ethnoracial minorities are often racialized and consequently excluded from various consumption contexts. Racialized market actors strive to overcome exclusion and gain participation in markets; however, these efforts are often insufficient because they cannot create equitable access to market resources, fair opportunities for voice, and empowerment to shape market practices. This research identifies digital enclave movements as a unique means by which racialized market actors redirect their resources and mobilize digital network tools to participate in markets. Using a qualitative study of the digital enclave #MyBlackReceipt, the authors explore tactics supporting the formation and sustenance of digital enclaves and how they support participation in markets. The authors identify five tactics that racialized market actors employ to foster digital enclaves and enhance market participation: legitimizing, delimiting, vitalizing, manifesting, and bridging. Last, the authors provide recommendations for policy makers on how to support and foster more equitable participation of ethnic minority groups in markets while addressing the risks of radicalization and the backlash related to enclaves.

Comparative Lessons in Sectional Title Laws: Mitigating Urban Inequality in South Africa.

Urban inequality in South Africa is a formidable problem that is linked to the injustices of its historical apartheid past. This paper identifies sectional titles, a form of property ownership where proprietors wholly own their apartment unit while co-owning the land and common property, as critical to providing more affordable housing. Sectional title schemes mitigate urban inequality by giving a greater proportion of the country the opportunity to own legally secure, well-located dwellings while serving as a platform where communal living could take place. Two suggestions how sectional title legislation can further alleviate aspects of urban inequality are made (1) Permitting a supermajority of sectional owners to terminate a sectional scheme prevents holdout and allows urban land to be redeveloped, providing an increase in housing. (2) Municipalities could consider mandating ethnic integration in sectional schemes to counter the organic formation of mono-racial residential enclaves which remain in present-day South Africa.

Assessing coastal urban sprawl in the Athens’ southern waterfront for reaching sustainability and resilience objectives

Waterfront management constitutes one of the most challenging research areas for spatial planning and a key driver for urban development. As such, it has unceasingly being placed at the epicenter of the scientific and policy-making debate over time. In a rapidly changing decision environment, marked by recession, climate change, urbanization, blue growth, etc., the interest in coastal zone management and related planning endeavours is constantly escalating. Raising is also the concern for serving sustainability and resilience objectives of urban coastal fronts, further amplified in case of coastal metropolitan regions, i.e. areas that are subject to intense urban sprawl pressures and intensification of land/sea uses. In such regions, population over-concentration and deployment of hyper-local infrastructures/functions leads to the formation of strong developmental enclaves along the coastline, with multiple consequences on the marine and coastal ecosystems, the local identity as well as the territorial and social cohesion of the coastal communities. Managing the fragile and highly vulnerable urban coastal zones is currently dealt with the Integrated Coastal Zone Management (ICZM). A key issue in this respect lies on the understanding of the causes behind coastal urbanization and their use in relevant planning endeavours, ending up with policy actions and institutional regulatory mechanisms. Having as a pilot field of research one of the most intriguing parts of the Athens’ southern waterfront (Faliro-Elliniko), the focus of this work is on: identifying the main drivers behind its structure/dynamics and degree of integration into the city; studying and evaluating its spatio-functional transformations; and illuminating the typological characteristics of the coastal zone that affect its vulnerability and spatial continuity. The ultimate goal is to highlight the necessity for a multi-dimensional and spatio-temporal approach for assessing coastal urban sprawl and monitoring its effects on the natural and manmade environment.

Retracted: Constructing civic identity among ethnic groups residing in enclaves

AbstractIn contemporary world conditions, characterised by rapidly developing social processes, the problem of the study of civic identity as part of social identity is becoming increasingly relevant. The purpose of this paper is to describe the results of a cross‐sectional study of the factors of constructing the civic identity of residents of the Maktaaral district of Kazakhstan—an enclave in the territory of Uzbekistan. The study involved 350 people from Myrzakent, the administrative centre of the Maktaaral district. The scientific novelty of the study lies in highlighting the main indicators of civic identity that are inherent in citizens of Kazakhstan living in the Maktaaral district in isolation from the parent state. The practical significance of the study is to identify the features of constructing civic identity among residents of this enclave formation. It was found that their civic identity was formed at the level of citizenship, the level of civic consciousness, and the level of patriotism. It was concluded that the territorial isolation of enclaves does not significantly affect the construction of civic identity construction.

Injection of enriched lithospheric mantle magmas explains the formation of microgranular enclaves in the Rio Jacaré Batholith, Borborema Province, Brazil

The Rio Jacaré Batholith (RJB; 617 ± 4 Ma) is inserted in the Poço Redondo Domain, Sergipano Orogenic System. This batholith is formed by monzodiorite, quartz monzodiorite, monzonite, and quartz monzonite, with abundant microgranular enclaves (MEs). The MEs vary from black to light gray and exhibit globular to slightly elongated shapes with clear-cut, crenulated, and cuspate, or, more rarely, diffuse contacts. They correspond to diorites, monzodiorites, quartz monzodiorites, and monzonites, and textural features indicate mixing of magmas, such as compositional zoning in plagioclase, inclusion zones in plagioclase phenocrysts, poikilitic alkali feldspar, acicular apatite, and ocellar quartz. Calculations of linear correlations of major elements showed that the smallest fraction of mafic magma involved in the mixing was 0.43. MEs represent the breakdown and cooling of a mafic magma that was injected into a cooler felsic magmatic chamber. Emplacement of this mafic magma occurred at different stages of crystallization of the RJB magmatic chamber. The MEs are magnesian and metaluminous, with affinity to the shoshonitic series. Ratios for Ba/Nb (> 23), Ba/La (> 15), and Nb/La (0.22–0.69) are characteristic of magmas generated from partial melting of an enriched lithospheric mantle source. Batch melting modeling suggests that source melting rates of less than 3% are necessary to generate magmas similar to those of the RJB MEs.

National and Ethnic Enclaves in the Modern World: Nature, Regulatory Instruments (Public Law Aspect). Part 2

As part of the study, the author has carried out the analysis of the problems of the risks of emergence of enclaves and defined the immanent threats, including enclavization (the phenomenon of “proto-enclave”) of the territories of some of the largest Russian urban agglomerations. The paper explores actual public law approaches to preventing the formation of national-ethnic enclaves in the Russian Federation (at national and regional levels of legal regulation) and suggests proposals for optimizing relevant approaches. The author substantiates the necessity of developing a comprehensive federal strategy of a framework nature covering the issues of spatial development, economy, social sphere, migration, demography, interethnic, interfaith, cultural policy. In order to implement a dispersed method of national-ethnic groups resettlement, based on the study of the experience of Sweden and Denmark, a position is argued about the rationality of expanding the scope of powers of local governments in the field of registration of migrants, normative fixation of the possibility of migrants living within specific municipalities (several specific municipalities). The author proposes to create unified centers for the distribution (location) of migrants, authorized to issue referrals to work in specific municipalities, taking into account their requests (needs) for a given workforce and reasons for the impossibility of attracting citizens of the Russian Federation living within specific municipalities to the relevant vacancies. Attention is drawn to the need to develop an integrated information resource on vacancies for migrants and on housing options available to them. The author emphasizes the importance of raising the qualification (competence) requirements for the profession and education of migrants, their relationship with integration of migrants into the host community, minimizing the risks of radicalization of the socio-cultural environment of migrant groups.

Frontiers of Soviet Resettlements: Cultural Borders and Cross-Cultural Interaction between Russians and Chuvashes in the South Part of Kama Region in the 1920-1930s

The article is devoted to the analysis of ethno-social resettlement campaigns of the USSR of the second half of the 1920s. The implementation of these practices in the Volga Region led to major migrations and the formation of ethnic enclaves on the territory of Urals and Siberia. Basing on various sources and field materials, the article describes the situation in the Southern Prikamye after several thousand of the Chuvash people migrated to the places inhabited by Russian Old Believers. The sources allow to reconstruct complex processes of ethno-cultural interaction that formed new specific complexes of spiritual and material culture of the Chuvash people of Prikamye. The authors noted that the resettlement in the 1920s took place in the conditions of the destruction of the traditional life characteristics in the whole country, a change in ideological attitudes, a significant transformation of ethnocultural complexes. Under the conditions of migration, these factors contributed to a more intensive course of assimilation processes. At the same time, a significant number of Chuvash migrants encamped in one area at a distance from large settlements, as well as preservation of the rural character of the outposts contributed to the functioning of institutions for keeping the traditional way of legacy transmission.

National and Ethnic Enclaves in the Modern World: Nature, Regulatory Instruments (Public Law Aspect). Part 1

National and ethnic enclaves constitute one of the forms of "parallel spaces" materialization (In the entire palette of inherent properties) and, therefore, it is legitimate to qualify them as a unique practice of refraction of the concept of multiculturalism. Historical experience has shown that the presumption of mutual desire for integration based on the recognition of the concept of multiculturalism as a guiding principle of relations (primarily in relation to European states and migrant groups within their borders) did not justify itself due to insufficient consideration of the entire scope of influencing factors (risks). On this basis, the author emphasizes the importance of applying an approach the structure of which includes differentiated complex methodological formulas (political and legal, socio-economic, national-cultural) that encourage harmonization of "foreign" authentic cultures (including religious practices, behavioural patterns in the framework of social environments) with a dominant and historically determined culture of the host community with the recognition of the primacy of its culture (including a heterogeneous nature).Enclaves are viewed as a spatial-geographical and socio-institutional phenomenon. The spatial and geographical component reflects the infrastructure landscape of the enclave, including the inherent economic, production, and environmental features in certain geographical coordinates (at the location). A socio-institutional variable characterizes a community that has appeared and functions by virtue of and within certain groups of co-identity parameters (national, religious, linguistic, legal (usually legal), etc.), emphasizes its inherent connections (internal and external). Under national-ethnic enclaves it is proposed to understand separate quasi-territorial formations, where, due to objectively forced conditions, national minorities (mainly migrant groups) live compactly (permanently or temporarily), adhering to an authentic way of life that differs from the generally accepted way (mainstream) in the host society. The paper highlights the characteristic imperative and optional features of enclaves, emphasizes the heterogeneous configuration of the social structure of enclaves, investigates the reasons for the formation and functions of ethno-national enclaves, identifies the similarities and differences between enclaves and ghettos and ethno-burbes.

Міграції чи культурні контакти: щодо теорії «ямної навали» на терени Центральної Європи

It is noted that some researchers have associated the migration of ancestors of Indo-Europeans to Europe with the Yamna cultural and historical community. It is established that based on a comparison of genomic markers from the remains of the Volga-Ural group of Yamna culture and representatives of European populations from the Mesolithic to the Bronze Age, Western geneticists recently proposed their concept of mass migration of bearers of Yamna culture to Central Europe, which led to the emergence of Corded ware culture. It is noted that from the archaeological point of view, neither this large-scale migration nor the origin of the «Corded ware culture people» from the «Yamna culture people» can be traced. It has been suggested that the formation of Corded ware cultures took place along with the formation of Yamna cultural community on a unified genetic substrate. It is noted that the similarity of genetic determinants in YCHC and CWC is not the result of the formation of one culture from another, but indicates a common genetic basis, which arose from complex processes of interaction between agricultural and steppe populations, which later developed according to individual cultural trajectories. The advance of the Yamna population to the west is considered as an intrusion into the local environment, not as its mass migration to Central Europe. It is assumed that there was a «trade colonization» with the formation of enclaves, covering the newcomers and the local population, with a gradual advance to the west. This is supported by the fact that in Central Europe about 20 burials of Yamna culture have been studied, which do not form a unified complex but occur in cemeteries of different cultures. It has been established that the main movement of the population of the Yamna culture to the west was along the Danube and partly through Transylvania, where the sites of CWC are unknown. The initial area from which the intrusion was carried out is the North-Western Black Sea region. It is concluded that such statistical information gives reason to doubt the mass migration of bearers of Yamna culture from the Volga-Ural watershed to Central Europe. It is noted that instead the migration of the Seredniodniprovska culture, which settled on the territory of the Northern Sub-Carpathian region and the Sokal Ridge, is much more clearly expressed. It has been established that the population of this culture joined the local CWC environment, forming syncretic sites with features of two and sometimes three (Yamna/Catacombna) cultures. It is known that after Seredniodniprovska culture the representatives of Catacombna culture penetrated Central Europe in the north-western direction. Their presence is most clearly traced in the environment of Strzyżowska culture. It has been established that the movement of the Babyne culture population to the territory of the Sub-Carpathian region, and especially to the Western Volhynia – to places where flint outcrops are localized, the environment of Horodok-Zdovbytsia and Strzyżowska cultures is increasingly observed. Key words: Yamna culture, Corded ware culture, Catacombna culture, Seredniodniprovska culture, Strzyżowska culture, migration, intercultural contacts, barrow, burial.
