-
(2000)The increasing analytical precision of 40Ar-39Ar geochronological data and its use in studies that combine U-Pb and 40Ar-39Ar data has necessitated derivation of a means to intercalibrate ages between the two isotopic ...
-
(2003)On the basis of an almost complete skull with the lower jaw from the Oligocene Shand-Gol Formation of the Ulan-Khureh locality in Mongolia, a new erinaceid genus and species, Scymnerix tartareus, is described. This is a ...
-
(1996)Analysis of the Oligocene mammalian fauna of Central Asia with consideration of the data on climatic evolution and geochronology revealed relations between major biotic events, which occurred in the studied region, and ...
-
(1987)The opening of the Arctic Ocean during the past 55 Ma resulted in relative rotation of America with respect to Eurasia about a pole located in eastern Siberia, near the plate boundary. The extensional plate boundary enters ...
-
(2002)A new mole, Mongoloscapter zhegalloi gen. et sp. nov. (Talpinae, Scaptonychini), is described on the basis of a fragmentary lower jaw from the upper part of the Shand Gol Formation of the Tatsin Gol locality. This is the ...
-
(2002)This is the second part of the monograph "Biogeography of the Northern Peri-Tethys from the Late Eocene to the Early Miocene." The main section, Biogeography of the Early Oligocene, considers the stratigraphy of the Lower ...
-
(2001)The regional stratigraphic scheme suggested for the marine Paleogene deposits in the West Siberian plate is based on investigation results of macro- and microfossils (foraminifers, dinoflagellales, radiolarians, diatomaceous ...
-
(1989)One of the tasks of the 21st cruise of the RV Yevpatoriya in the Black Sea in 1988 was to search for accumulations of gas hydrates supplied by an underwater mud volcano, and inferred to exist there by analogy with those ...
-
(2000)New high-resolution seismic reflection data from the central part of Lake Baikal provide new insight into the structure and stratigraphy of Academician Ridge, a large intra-rift accommodation zone separating the Central ...
-
(2004)The first findings of dinocysts Pseudokomewuia in Western Siberia are analyzed from the viewpoint of their significance for solving the questions of stratigraphy, paleogeography and paleoecology of basins in Cenozoic era.
-
(2002)The giant Mn ore deposits of the Paratethys are located on the slopes and/or margins of deep basins. The Eocene ocean and associated basins were strongly influenced by large-scale submarine hydrothermal activity which ...
-
(1989)Analysis of the evolution of Phanerozoic stratigraphic complexes of the western margin of the East European craton (EEC) and the Central European Platform (CEP) shows that their formation depended on the corresponding ...
-
(2001)The highest and longest ridges of the East Yakutian mountainous province exist on its periphery as the Verkhoyansk system in the west and the Chersky and Moma systems in the east. Northward, the ridges give way to the ...
-
(1997)Thermal structure of the crust beneath the Domandorsky Basin was modeled in the context of its tectonic evolution as a result of backarc rifting processes. The good fit of the theoretical heat flow to the results of heat ...
-
(2001)This study is based on the isotope-geochemical characteristics of oils from 53 fields in the South Caspian Basin - from Upper Cretaceous, Eocene, Oligocene-Lower Miocene (Maykop), middle and the Upper Miocene (Diatom) and ...
-
(2001)The east Anatolian plateau and the Lesser Caucasus are characterised and shaped by three major structures: (1) NW- and NE-trending dextral to sinistral active strike-slip faults, (2) N-S to NNW-trending fissures and /or ...

-
(1985)Episodic volcanism favors, as shown by examples from Europe, the USA, and Brazil, the formation of organic-rich sediments (hydrocarbon source rocks). The examples examined from Europe comprise the Lower Carboniferous ...
-
(2003)Four new taxa of the subfamily Brachyericinae, Exallerix manahan sp. nov. (Lower Oligocene of Mongolia), Synexallerix otus gen. et sp. nov. (Lower Miocene of eastern Kazakhstan), Postexallerix securis gen. et sp. nov. ...
