Abstract A comparative quantitative analysis of late Paleozoic subsidence in the Moscow and Dniepr-Donets basins provides additional insight into the relative importance of tectonics and eustacy as sedimentation driving forces. Late Devonian rifting clearly displayed in the Dniepr-Donets Basin and underlying Precambrian East European Craton probably also affected the Moscow Basin. After this episode, however, the history of both basins diverged ; rifting processes ceased in the Moscow Basin but continued in the Dniepr-Donets Basin. The Moscow Basin is an intracratonic basin that can be modelled with a lithospheric heating phase from Devonian to Bashkirian times and a subsequent cooling phase generating thermal subsidence from Moscovian to Asselian times. The Dniepr-Donets Basin is a rift basin displaying an initial rifting phase during the late Devonian, an initial phase of post-rift evolution from the Tournaisian to the base of late Viséan, and a second rifting phase, seen mainly in the Donets and Donbas segments only, from late Viséan to Asselian times. Subsequent subsidences ended with uplift during the Sakmarian and were overprinted by compressional tectonics during Mesozoic and Cenozoic times. A comparison of local and global second-order stratigraphic sequences, allowing an estimation of the ratio of the importance of eustatic to tectonic processes controlling subsidence in each basin, demonstrates that eustacy controlled sedimentation in the Moscow Basin and tectonics prevailed in the Dniepr-Donets Basin.

The Relationship

Abstract This article explores relations between Muscovy and the so-called Later Golden Horde successor states that existed during the fifteenth and sixteenth centuries on the territory of Desht-i Qipchaq (the Qipchaq Steppe, a part of the East European steppe bounded roughly by the Oskol and Tobol rivers, the steppe-forest line, and the Caspian and Aral Seas). As a part of, and later a successor to, the Juchid ulus (also known as the Golden Horde), Muscovy adopted a number of its political and social institutions. The most crucial events in the almost six-century-long history of relations between Muscovy and the Tatars (13–18th centuries) were the Mongol invasion of the Northern, Eastern and parts of the Southern Rus’ principalities between 1237 and 1241, and the Muscovite annexation of the Kazan and Astrakhan khanates between 1552 and 1556. According to the model proposed here, the Tatars began as the dominant partner in these mutual relations; however, from the beginning of the seventeenth century this role was gradually inverted. Indicators of a change in the relationship between the Muscovite grand principality and the Golden Horde can be found in the diplomatic contacts between Muscovy and the Tatar khanates. The main goal of the article is to reveal the changing position of Muscovy within the system of the Later Golden Horde successor states. An additional goal is to revisit the role of the Tatar khanates in the political history of Central Eurasia in the fifteenth and sixteenth centuries.

West Siberian Basin

The West Siberian Basin (WSB) is one of the largest intracratonic Meso-Cenozoic basins in the world. Its evolution has been studied over the recent decades; however, some fundamental questions regarding the tectonic evolution of the WSB remain unresolved or unconfirmed by analytical data. A complete understanding of the evolution of the WSB during the Mesozoic and Cenozoic eras requires insights into the cooling history of the basement rocks as determined by low-temperature thermochronometry. We presented an apatite fission track (AFT) thermochronology study on the exposed parts of the WSB basement in order to distinguish tectonic activation episodes in an absolute timeframe. AFT dating of thirteen basement samples mainly yielded Cretaceous cooling ages and mean track lengths varied between 12.8 and 14.5 μm. Thermal history modeling based on the AFT data demonstrates several Mesozoic and Cenozoic intracontinental tectonic reactivation episodes affected the WSB basement. We interpreted the episodes of tectonic activity accompanied by the WSB basement exhumation as a far-field effect from tectonic processes acting on the southern and eastern boundaries of Eurasia during the Mesozoic–Cenozoic eras.

This commentary reviews the responses to an earlier article, ‘Palestine in an International Historical Perspective on Genocide’ (Holy Land Studies, 9:1, 1–25), arguing that they illustrate both the possibilities and the limitations of serious debate about these issues. The responses mostly neglected the analytical core of the argument relating to 1948, which is therefore restated, emphasising Palestine's unique combination of elements that were parts of three general patterns implicated in genocide production (settler colonialism, East European nationalism, conflicts of decolonisation). The paper also gives further attention to the implications of the perspective for understanding the ‘genocide’ question in the subsequent history of the Israel-Palestine conflict.

The purpose of this article is to provide a historical background of medicine, science and sports with the focus on the development of modern sports medicine in European countries, with an accent on Eastern European countries that have a long sports medicine tradition. The development of modern sports medicine began at the end of 19th and the beginning of 20th century, and it has been associated with social and cultural changes in the world of medicine, science and sports. Advanced medical knowledge, skills and practices, and the progress of scientific achievements enabled sports people to improve their performance level. Increased popularisation and commercialisation of sports have resulted from urbanization and city lifestyle, leading to the lack of physical activity and increased psychological pressure. In addition, the growing need and interest in sports and successes in professional sports have become a symbol of international recognition and prestige for the nations.

<p>There's no doubt that nowadays detrital zircon U-Pb geochronology is actually required method of sedimentary basins analysis. Furthermore, this approach may have a lot of applications, such as a stratigraphic correlation. Here we present the first results of U–Pb LA–ICP–MS dating of detrital zircon from the Permian-Triassic red beds located within the Moscow Basin of the East European platform. Two outcrops have been studied: the Zhukov Ravine P/T boundary reference section and the Nedubrovo strata with uncertain stratigraphic position (uppermost Permian or lower Triassic?).</p><p>U–Pb ages of detrital zircon grains have been obtained for two samples – the Upper Permian and Lower Triassic age, which were taken in the proximity to the Permian–Triassic boundary in the Zhukov Ravine. Corresponding age distributions show contrasting provenance of the studied sedimentary rocks, pointing out that principal change in source of clastic material occurred on the Paleozoic-Mesozoic boundary. It means that detrital zircon U–Pb geochronology can be used as an additional independent tool for stratigraphic correlation of the Permian-Triassic red beds, at least within the Moscow Basin. We demonstrate this in the case of the Nedubrovo section with debated (Permian or Triassic?) stratigraphic position: the obtained data on detrital zircons persuasively suggests Early Triassic age of the Nedubrovo strata.</p><p>This study is supported by the Russian Foundation for Basic Research (project no. 18-05-00593).</p>

Historical Role

The novel “Magnus, the Danish Prince” by the Russian diaspora in Latvia writer Roald Dobrovensky is seen as a specific example of a biographical and historical genre, which embodies the historical experience of different eras and nations in the confrontation of globalisation and national self-determination. At the heart of the novel are the Livonian War and the historical role and human destiny of Magnus (1540–1683) – the Danish prince of the Oldenburg dynasty, the first and the only king of Livonia. The motif of Riga’s humanists is seen both as one of the main ideological driving forces of the novel and as a marginal reflection in Magnus’s life story. Acknowledged historical sources have been used in the creation of the novel: Baltazar Rusov’s “Livonian Chronicle”; Nikolai Karamzin’s “History of the Russian State”; Alexander Janov’s “Russia: 1462–1584. The Beginning of the Tragedy. Notes of the Nature and Formation of Russian Statehood” etc. In connection with the concept of Riga humanists, another fictitious document created by the writer Dobrovensky himself is especially important, namely, the diary of Johann Birke – Magnus’s interpreter, a person with a double identity, “half-Latvian”, “half-German”. It is a message of an alternative to the well-known historical documents, which allows to turn the Livonian historical narrative in the direction of “letocentrism” and raises the issue of the ethnic identity of Riga’s humanists. Along with the deconstruction of the historically documented image of Livonian King Magnus, the thematic structure of the novel is dominated by identity aspects related to the Livonian historical narrative. Dobrovensky, with his novel, raises an important question – what does the medieval Livonia, Europe’s common intellectual heritage, mean for contemporary Latvia and the human society at large? Dobrovensky’s work is also a significant challenge in strengthening emotional ties with Livonia (which were weakened in the early stages of national historiography due to conflicts over the founding of nation-states).

AbstractA complex interplay of palaeoclimatic, eustatic and tectonic processes led to fragmentation and dissipation of the vast Tethys Ocean in Eocene-Oligocene times. The resulting Paratethys Sea occupied the northern Tethys region on Eurasia, grouping water masses of various subbasins, separated from each other and from the open ocean through narrow and shallow gateways and land bridges. Changes in marine gateway configuration and intra-basinal connectivity affected the regional hydrology, shifting most Paratethyan basins to extreme carbon-sink anoxic environments, anomalohaline evaporitic or brackish conditions or even endorheic lakes. Paratethys gateway restriction triggered the onset of a long-lasting (∼20 Myr) giant anoxic sea, characterised by stratified water masses and anoxic bottom water conditions, resulting in thick hydrocarbon source rocks. Here, we review the geological evolution of the “dire straits” of Paratethys that played a crucial role in the Eocene-Oligocene connectivity history of the Central Eurasian seas and we show that the main anoxic phases (Kuma and Maikop) correspond to restricted connectivity with the global ocean and a period of CO2 depletion in the atmosphere. Paratethys represents one of the largest carbon sinks of Earth's history and may thus have played a prominent role in global climate change.

The origin of tetrapods from sarcopterygian fish in the Late Devonian is one of the best known major transitions in the history of vertebrates. Unfortunately, extensive gaps in the fossil record of the Lower Carboniferous and Triassic make it very difficult to establish the nature of relationships among Paleozoic tetrapods, or their specific affinities with modern amphibians. The major lineages of Paleozoic labyrinthodonts and lepospondyls are not adequately known until after a 20–30 m.y. gap in the Early Carboniferous fossil record, by which time they were highly divergent in anatomy, ways of life, and patterns of development. An even wider temporal and morphological gap separates modern amphibians from any plausible Permo-Carboniferous ancestors. The oldest known caecilian shows numerous synapomorphies with the lepospondyl microsaur Rhynchonkos. Adult anatomy and patterns of development in frogs and salamanders support their origin from different families of dissorophoid labyrinthodonts. The ancestry of amniotes apparently lies among very early anthracosaurs.

“Going West” explores the potential of integrating East European History into broader histories of Europe and the world. Placing the history of Eastern Europe in a European context, I argue, may enable us to challenge the tropes of backwardness, pathology, and violence that still dominate the field. I also suggest that historians explore the extent to which conceptions of minority rights, development, and humanitarianism first developed in Eastern Europe radiated beyond the region in the twentieth century.
