CORRELATION OF THE PRECAMBRIAN SECTIONS OF THE SIBERIAN AND CHINESE PLATFORM DEPOSITS BY OIL AND GAS CONTENT PROSPECTS

The Purpose of the study is to carry out the correlation of profiles of the Precambrian deposits of the Siberian and China platforms, to compare tectonic scales by the age of the Precambrian final folding, to distinguish geological and structural backgrounds of the oil-and-gas content of Siberian and North China platform Rifeide (siniede). The Methods used in the study include the comparison of the coeval structural and material complexes formed in similar geodynamic conditions, correlation of classical basic profiles of the Precambrian of the Siberian platform, its southern frame and the North China platform. Results. The scales of structural and material complexes of the Precambrian of Siberia and China are composed. The correlation is performed which is based on the regional scales of structural and material complexes, that is material expression of regional geological systems of Siberia and China, and age-wise tectonic scales, which are also accepted in Russia and China. It is noted that drastic change in the orientation of the Riphean structures with the Pre-Riphean structures on the Asian continent coincides with the Liu Liang movement, which corresponds to the Vyborg movement on the territory of Europe, to early Riphean movement in Siberia, to the Hudson movement in the American continent: 1800-1600 million years. This planetary stage of continental destructions is also the time of disintegration of the Sino-Siberian pracontinent into the Siberian and North China cratons. The detailed analysis of the Pre-Riphean evolution of Sino-Siberian pracontinent and the geological history of the Riphean structures has allowed to distinguish the geological-structural backgrounds of the oil-and-gas content of the Siberian and North China platform Rifeides (sineides). Conclusions. The correlation of the Precambrian of the Siberian and North China platforms shows the analogy of the structural-material complexes composition. The comparison of tectonic scales by the age of final folding allows to draw a conclusion on the industrial oil-and-gas content of the Riphean and Sinian formations on the Siberian and China platforms.
