(2001)U–Th–Pb analyses of zircons from six granites and one metasediment collected in the accretionary Central belt of Taimyr, Arctic Siberia, demonstrate that Neoproterozoic (c. 900 Ma) granites intrude late Mesoproterozoic/early ...
-
(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 ...
-
(1999)Carbon and oxygen isotope variation curves for Vendian-Lower Cambrian carbonates of the Bokson Group are correlative with those characterizing coeval sections in Siberia and western Mongolia. The curves demonstrate the ...
-
(1989)Most oil and gas pools found in the Lena-Tunguska oil and gas province of the Siberian craton are known to be confined to granular or fractured-granular reservoir rocks in clastic sandstone-siltstone strata. Such rocks ...
-
(2003)The Vendian-Early Cambrian, Middle Cambrian, and Early Ordovician volcanosedimentary deposits of the Martaiga Block of the Kuznetsk Alatau paleoisland arc (55.5° N, 88° E) have been investigated paleomagnetically. Their ...
-
(2001)The age of ophiolite plagiogranites from the Khan-Taishiri ophiolite complex, western Mongolia, was determined by the U-Pb zircon method as 568.1 ± 4.0 Ma. This complex is a rare fragment of the ancient Central Asian blocks ...
-
LATE VENDIAN POTASSIC VOLCANIC ROCKS OF THE OLENEK HIGHLANDS ON THE NORTHEAST OF THE SIBERIAN CRATON (1989)The authors investigated a rock complex in the northern part of the Olenek Highlands on the Siberian craton, where it lies in the Khorbusuonka, Erkeket, and Kersyuke river basins. These potassic volcanics are found over ...
-
(2002)In the Vendian-Cambrian orogenic belt of the Chagan-Uzun and Kurai areas, Gorny Altai, high-pressure, low-temperature (HP/LT) metabasites and associated schists comprise a metamorphic complex less than 2 km thick. The ...
-
(1989)The microfossils of the genus Obruchevella, established by Ye. A. Reytlinger in the lower Paleozoic and Vendian deposits of the Siberian craton and for a long time unknown elsewhere, have recently attracted ever-increasing ...
-
(2004)New paleontological findings, analysis of section structure, and literature data on the Neoproterozoic stratigraphy of the Altai-Sayan Folded Area, ASFA, provide support to the recognition of three heterochronous polyfacies ...
-
(1990)The presence of igneous rocks of mafic composition (diabases and dolerites) in the caprock of the Seregovo salt dome, about 75 km north of Syktyvkar, in a platform region with a large area of Mesozoic-Cenozoic sedimentary ...
-
(2004)New palaeomagnetic poles obtained from the Vendian tuffs and basalts of western Ukraine indicate the necessity of a substantial revision of the Late Vendian-Early Cambrian palaeogeography of the Baltic plate. The palaeopole ...
-
(2004)The new taxa Vendia rachiata sp. nov. and Cyanorus singularis gen. et sp. nov. are described from the Upper Vendian of the Onega Peninsula, Arkhangel'sk region. These taxa belong to the invertebrate phylum Proarticulata, ...
-
(2001)The collection numbers of A.G. Vologdin, A.N. Vlasov, Yu.I. Voronin, K.N. Konjuschkov, and V.I. Yaworski on archaeocyaths and certain other Vendian and Cambrian fossils, which were transferred to the Stock Division of the ...
-
(2001)A palaeomagnetic study of Vendian and Early Cambrian sediments from the Angara block of the Siberian platform: Shaman (52.08°N, 108.83°E) and Minya (58.0°N, 110.0°E) Formations, and the Tuva-Mongolian block: Tsagan-Olom ...
-
(2001)On the basis of T- and AF-demagnetisation carried out in the course of studies of Neo-Proterozoic paleobasalts (of the Volyn Series, Lower Vendian) and terrigenous rocks (of the Grushki Suite, Lower Vendian and of the ...
-
(2002)Paleomagnetic results from an Upper Vendian sedimentary sequence exposed along the White Sea shoreline, NW Russia are described. These classical exposures have been the subject of intense paleontological investigations due ...
-
(1985)Abstract Paleomagnetic research in the Siberian area provides new data to derive models of relative horizontal movements and the process of amalgamation or consolidation of the Siberian plate. Comparison of the Apparent ...
-
(2003)The carbonate rock investigation was based on the combined analysis of U-Pb- and Rb-Sr-systematism for the same samples. For the first time in the practice of studying the Upper Yudoma carbonate rocks of Eastern Siberia ...
-
(2001)The subalkaline magmatism in the western slope of the Urals is an indicator of rifting processes, which accompanied the splitting of the Rhodinia supercontinent at the boundary of the Late Proterozoic and Early Paleozoic. ...
