Modelling of the hydrocarbon sphere of Siberian platform
56th EAEG Meeting, 1994Oil and gas deposits discovered now, are fragments of the hydrocarbon sphere of the Earth. This sphere features discontinuously - continuous structure comprising both dispersed and concentrated hydrocarbon forms in solid, liquid and gaseous states and their combinations.

On the genesis of trapp magmatism of the Siberian platform
Earth and Planetary Science Letters, 1989Abstract Mathematical modelling of thermal thickening of the lithosphere with time indicates that the thickness of the lithosphere beneath the Siberian platform in the late Permian and Triassic, when intensive trapp magmatism occurred, differed insignificantly from the present thickness.

THE ORIGIN OF THE SIBERIAN PLATFORM
International Geology Review, 1964The paper explores the two divergent schools of thought on the origin of the Siberian platform: 1) the Delanee concept visualizing the formation as the result of terminal Precambrian (Baykal'ian) deformation that knit various independent Archean units into a single body which grew by accretion of peripheral folded belts, and 2) a new concept developed ...

Deep seismic studies of the territory jointing the western Siberian and Siberian Platforms
International Geology Review, 1968As a result of regional seismic research by the method of isolated seismic sounding with waves of different types, the peculiarities of the wave field and main features of abyssal structures of the earth's crust are ascertained throughout the line: western Siberia lowland, the Yenisey mountain range, and the western part of the Siberian Platform ...

PETROCHEMICAL TYPES OF KIMBERLITES ON THE SIBERIAN PLATFORM
Russian Geology and Geophysics, 1991Results of cluster and factor examination of 154 published chemical analyses on the Siberian platform kimberIites are given to cover the whole field of possible compositions of kimberlites. In this field, 12 petrochemical types of kimberlites have been recognized: 4 weakly altered types - magnesian and calcium-magnesian basaltoid kimberlites, magnesian

“Cuboids” of pyrope found in Siberian Platform
International Geology Review, 1971Pseudocubical convex-faceted grains of pyrope are often found in upper parts of weathered crust, in sedimentary rocks and in modern alluvium, inside and outside the Yakutian diamond fields. They are never in the diamond pipes or in dense kimberlites where pyrope maintains its normal shape.

FACIES OF PHOSPORITE DEPOSITS IN THE SIBERIAN PLATFORM
International Geology Review, 1964Describes Middle Ordovician shell phosphorites with P2O5 content of up to 14 percent on Aka and Angara rivers; detrital granular phosphorites 10 cm lenses of material with up to 20 percent P2O5, and phosphorite conglomerates up to 10 cm thick and containing up to 10 percent P2O5 in Lena river valley; and phosphate ferruginous rocks with P2O5 content of

Experience of Multicomponent Observations on Siberian Platform
GeoSiberia 2007 - International Exhibition and Scientific Congress, 2007Использование комплекса продольных и обменных волн представляет целый ряд преимуществ [1,2]. Совокупность отражённых P- и PS-волн даёт наиболее полную информацию о строении геологического разреза, поскольку отражающие свойства границ для этих волн различны.

Electrical conductivity of the crust of the Siberian platform
Physics of the Earth and Planetary Interiors, 1989Abstract Interpretation of magnetotelluric soundings on the Siberian platform suggests the presence of anomalously high conductivities in the lower crust around a depth of 35 km. The most probable explanation of this phenomenon is the presence of supercritical fluid in pores and microcracks.
