On the Nonmarine Cretaceous Stratigraphy and Floras of Northeastern Russia
Stratigraphy and Geological Correlation - Tập 27 - Trang 311-322 - 2019
Some decisions of the Third Interdepartmental Regional Stratigraphic Meeting on Precambrian, Paleozoic, and Mesozoic of Northeastern Russia (St. Petersburg, 2002) are analyzed in light of the latest data obtained. The regional stratigraphic units (“horizons”) of the nonmarine Cretaceous recognized at this meeting are in fact not the basic subdivisions, but rather specialized biostratigraphic units...... hiện toàn bộ
Large mammals from the Upper Neopleistocene reference sections in the Tunka rift valley, southwestern Baikal Region
Stratigraphy and Geological Correlation - Tập 23 - Trang 214-236 - 2015
This work presents the data on new finds of fossil macrotheriofauna in the reference sections of the Upper Neopleistocene sediments in the Tunka rift valley (southwestern Baikal Region). The osteological material of a number of Late Neopleistocene mammals including extinct species rare for the Baikal region such as Crocuta spelaea, Panthera spelaea, and Spirocerus kiakhtensis (?) was directly date...... hiện toàn bộ
Comments on the “Debatable Aspects of Initial Human Colonization of Siberia and Age of the Karama Site in the Altai Mountains” by V. S. Zykin, V. S. Zykina, and L. G. Smolyaninova
Stratigraphy and Geological Correlation - Tập 28 - Trang 567-569 - 2020
In this publication, the discussion is focused on issues related to the stratigraphy and chronology of the Karama Lower Paleolithic site in the Altai Mountains in light of the article “Debatable Aspects of Initial Human Colonization of Siberia and Age of the Karama Site in the Altai Mountains” by V.S. Zykin, V.S. Zykina, and L.G. Smolyaninova published in Stratigraphy and Geological Correlation in...... hiện toàn bộ
Radiolarian paleobiogeography in the late Albian–Santonian
Stratigraphy and Geological Correlation - Tập 24 - Trang 575-601 - 2016
Radiolarian paleobiogeography for the late Albian–Santonian is proposed for the first time. The paleobiogeographic differentiation is found to be different for the Albian, Cenomanian, Turonian, and Coniacian–Santonian. The Tethyan and Boreal superrealms can be recognized for the Albian–Santonian. For the Albian–Santonian, the Tethyan Superrealm can be subdivided into realms: Atlantic-Mediterranean...... hiện toàn bộ
Late Cretaceous radiolarians of the genera Cuboctostylus Bragina and Hexacromyum Haeckel: Their stratigraphic and paleobiogeographical distribution
Stratigraphy and Geological Correlation - Tập 21 Số 1 - Trang 79-95 - 2013
Radiolarian Biostratigraphy of the Bazhenovo Regional Substage (Upper Jurassic–Lower Cretaceous) of Western Siberia
Stratigraphy and Geological Correlation - Tập 28 - Trang 665-683 - 2020
On the basis of published and new data, the features of the history of study of radiolarians and their stratigraphic distribution in the Upper Jurassic–Lower Cretaceous Bazhenovo Regional Substage (Tithonian–Berriasian) of the West Siberian depositional basin are summarized and analyzed. A general geological characteristic of the Bazhenovo Formation is given. The previous regional schemes are brie...... hiện toàn bộ
Geochronology, stratigraphy, and evolution of Middle Uralian peatlands during the Holocene (exemplified by the Shigir and Gorbunovo peat bogs)
Stratigraphy and Geological Correlation - Tập 22 - Trang 632-654 - 2014
Integrated studies on several peat-gyttja sections, including Mesolithic and Neolithic cultural layers, were conducted for the Shigir and Gorbunovo peatlands of the Middle Urals. The results of plant macrofossil and pollen analyses were used to reconstruct the history of peat formation, vegetation, and climate changes during the Holocene. The radiocarbon dating of archaeological artifacts and encl...... hiện toàn bộ
Faunistic Substantiation of Stratigraphic Occurrence of the Pleuromeia (Isoëtopsida) Plant in the Triassic of Gorny Mangyshlak, Republic of Kazakhstan
Stratigraphy and Geological Correlation - Tập 26 - Trang 283-297 - 2018
Joint burial places of mollusks and Pleuromeia plants allow specification of a period of stratigraphic occurrence of this genus in the west of the Republic of Kazakhstan within the Gorny Mangyshlak. Two places of occurrences of pleuromeias were found in marine Triassic rocks: one in the Karadzhatyk Formation of the northern slope of the Karatauchik Range close to the Dolnapa well, where the fossil...... hiện toàn bộ

Middle–Upper Devonian Terrigenous Rocks of the Tsil’ma River Basin and Their Palynological Characteristics
Stratigraphy and Geological Correlation - - 2019
The results of biostratigraphic study of Givetian–Frasnian rocks of the Tsil’ma River basin (Middle Timan) are presented. The biostratigraphic division of the sections is based on palynological data: five palynocomplexes are distinguished in the Valsa, Tsil’ma, Ust’-Chirka, Ust’-Yarega, and Kraipol’e formations and are correlated with coeval palynocomplexes of adjacent of territories. The features...... hiện toàn bộ
