(2004)Investigation of the Triassic–Lower Cretaceous rocks of the Dal'negorsk key section (southern Sikhote Alin) revealed the following successive associations of authigenic clay minerals: (1) sericite–chlorite (Lower Triassic); ...

CLIMATE DURING PERMIAN-TRIASSIC BIOSPHERE REORGANIZATIONS, ARTICLE 1: CLIMATE OF THE EARLY PERMIAN (2002)The Permian was marked by transition from the glacioera to the thermoera, the last one in the geo- logical history. This global climatic reorganization followed the significant paleogeographic changes related to Pangea ...
-
(2003)The Late Permian-initial Triassic was a period of the Earth climate change, as the glacial climate of the Late Paleozoic was replaced by the non-glacial one of the Mesozoic. The intricate trend of this process is reconstructed ...
-
COMPARATIVE ANALYSIS OF GEODYNAMIC SETTINGS OF THE PERMO-TRIASSIC MAGMATISM IN EAST AND WEST SIBERIA (1999)A comparative analysis of the chemical composition of Permo-Triassic volcanics from the Siberian Platform and pre-Jurassic basement of the West-Siberian plate was performed to elucidate the geodynamics of magmatism in these ...
-
(2002)Some Triassic key sections of Siberia and the eastern Urals are characterized in terms of paleontology. In the northeastern Siberia, these are sequences of the Cape Tsvetkov (the eastern Taimyr Peninsula) and the Ust'-Anabar ...
-
(1998)The analyzed distribution ranges of tetrapods, ostracods, megaspores, and other fossils were used, with due regard for the facial dependence and phylomorphogenetic lineage, to resolve correlation problems concerning Triassic ...
-
(1988)The development of the Kurile island arc is though to have begun in the Late Cretaceous. In the Neogene deposits on northern and southern islands of this ridge, including Kunashir, there are well-rounded fragments of granite ...
-
(2005)40Аг/39Аг датированием установлено, что формированию крупного Cu-Mo-порфирового месторождения Эрдэнэтуин-Обо, связанного со становлением эрдэнэтского рудоносного порфирового комплекса, предшествовало развитие в районе ...
-
(2001)A new monobasic genus Eovavilovites (type species E. delinensis) is described from the Induan of Yakutia. The taxonomy and phylogeny of the new genus are discussed.
-
(2004)An extensive palaeomagnetic study was carried out on an approximately 250 Ma old reversed to normal transition of the Earth’s magnetic field (EMF) recorded in 86 volcanic lava flows of the Siberian trap basalts, North ...
-
(2001)A new primitive sauropterygian from the Donskaya Luka locality (Don River, European Russia) is described as a new genus and species of the family Cymatosauridae, Tanaisosaurus kalandadzei gen. et sp. nov. This is the first ...
-
(2001)The backstripping method that is widely used in basin analysis sometimes fails for salt-bearing basins because the highly mobile and buoyant salt deforms its sedimentary overburden. We present a numerical approach for 2-D ...
-
(2009)The Altaids is one of the largest accretionary orogenic collages in the world with the highest rate of Phanerozoic continental growth and significantmetallogenic importance. It is widely accepted that subduction-related ...
-
(2000)Volumes of various trap-magmatic facies have been evaluated by invoking deep-drilling data, geophysical data, field studies, and recent notions of the geodynamic settings of their formation at the Permo-Triassic boundary. ...
-
(1990)Most authors now accept that kimberlite magmatism was confined to cratons. M.A. Kamaletdinov, Yu. I. Kazantsev and other authors have now proved that within the Ural foredeep there are thick overthrust zones. Their data ...
-
(2004)The evolutionary history of six genera of Early Triassic Boreal Dinaritaceae (Hypophiceras, Tompophiceras, Metophiceras, Sakhaitoides, Sakhaites, and Kelteroceras) is discussed, and patterns and pathways of their evolutionary ...
-
(2003)On the basis of generalizations and analysis of new materials on regional and thematic research, the main problems involved with the evolution of the Paleo-Аsian ocean and structure of the huge Ural-Mongolian Fold Belt ...
-
(2001)The evolution of the phylogenetically linked early Triassic genera Anaxenaspis, Lepiskites, Clypeoceratoides, and Koninkitoides is discussed. This lineage shows a combination of direct and complex recapitulations. All ...
-
(2004)We have analysed 129 stratigraphic sections from the Timan-Pechora basin, from its adjacent continental shelf and from the South Barents Sea basin, in order to determine whether existing models of extensional sedimentary ...
