(1993)An endemic fusulinid assemblage is herein first described from Sakmarian rocks of the Central Pamir. It consists of 42 species and subspecies belonging to the genera Pseudofusulina, Sphaeroschwagerina, Paraschieagerina, ...
-
(2004)Palaeomagnetic and faunal data have been re-evaluated on a global basis for the period from 400 Ma (early mid-Devonian) to 250 Ma (latest Permian). The boundaries of the major terranes are considered and defined. Six new ...
-
(2006)In spite of significant quantity of publications, devoted to different aspects of the East European (Russian) platform geology, the joint analysis of structure and sedimentation evolution has not been made. The paper deals ...
-
(2003)Accessory monazites from 35 granitoid samples from the Western Carpathian basement have been analysed with the electron microprobe in an attempt to broadly constrain their formation ages, on the basis of their Th, U and ...
-
(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 ...
-
(2003)The collections of primitive therapsids from the Upper Permian of Eastern Europe are revised. Morphological examination has shown that the main principles for the establishment of the subclass Theromorphu should be revised. ...
-
(2001)In the history of the Kazanian sea basin in the Russian plate, periods of quasi-stationary shoreline position alternated with quick phases of transgressions and regressions. The last events were responsible for appearance ...
-
(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 ...
-
(2003)The data on the morphology, systematics, stratigraphy, and ecology of seymouriamorphs (Parareptilia) are revised. Cranial morphology of ten seymouriamorph species belonging to seven genera and three families from the Lower ...
-
(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 ...
-
(1995)The Siberian Traps represent the largest known Phanerozoic manifestation of continental flood volcanism. The general agreement is now that the volcanism was of short duration (# 1 m.y.) and was synchronous with the ...

(1995)The Siberian Traps represent the largest known Phanerozoic manifestation of continental flood volcanism. The general agreement is now that the volcanism was of short duration (∼ 1 m.y.) and was synchronous with the ...
-
(2004)A 300-m (1000-ft)-thick succession of shallow- and warm-water carbonates has been studied in well cores from the southernmost Barents Sea, offshore north Norway. These upper Paleozoic strata contain numerous zones of ...
-
(2001)Finds of juvenile parareptiles are rare in the fossil record. We describe partial upper dentition with large vacuities between bones belonging to a neonate pareiasaur (preserved skull fragment is 22.4 mm long). The specimen ...
-
(1990)One of us (V.I.D.) has been investigating the tectonics, stratigraphy and the age of the rocks of the Rushan-Pshart region since 1959. We refocused our research to siliceous beds, in the hope of finding radiolarians or ...
-
(2001)First ammonoid remains are found in the Lower Permian Munugudzhak Horizon, the northwestern coast of the Kotel'nyi Island (New Siberian Islands). They are used to define more precisely the age of host deposits and to clarify ...
-
(1989)The basanite explosion pipes in the area of the Kop'yevo uplift in the Chulym-Yenisey basin (CYB) are widely known because they contain xenoliths of peridotite, pyroxenite and megacrysts of other minerals and others). ...
-
(ГЕОС, 2016)В монографии дан подробный анализ пермской флоры Западной Ангариды (Среднее и Южное Приуралье) с привлечением данных из соседних регионов (Печорское Приуралье, центральные районы Ангариды). Приведены сведения об изученных ...
-
(2003)A huge fluorite deposit at Voznesenka in the Khanka massif, Far East Russia is concluded to have formed at ca. 450 Ma in Late Ordovician time based on the K-Ar ages for Li-micas in the fluorite ore and greisenized leucogranite ...
-
(1996)Seven alkylaromatic hydrocarbons with an isohexyl and a methyl substituent group on adjacent ring carbons have been identified in a suite of crude oils derived from a range of locations, source types, palaeoenvironments, ...
