Oil and gas basins (OGB) of active and transform margins of the Pacific Ocean are discussed. Their western and eastern parts differ substantially in the evolution, tectonic pattern, and scope of resources. In the west, marginal seas incorporated into the Cenozoic geodynamic system of deep-water basins (marginal seas) and conjugate island arcs exhibit a greater oil and gas potential (hereafter, petroleum potential) as compared to the eastern margin bounded by a deep-water trench and transformed into the framing with OGBs only in separate sectors. The abundance of siliceous rocks influenced the formation and accumulation of oil and gas in the Pacific region. The most part of hydrocarbon accumulations is related to organogenic edifices and channels of shelf fans. Oil and gas fields confined to fans on slopes of deep-water troughs of active and transform margins are also known. Proceeding from the global practice, significant petroleum potential in Russia is associated with back-arc seas of the Pacific. The poorly studied deep-water basins on slopes are worthy of special attention. 相似文献

The tectonic and geodynamic evolution of the southern European part of Russia from the Donets Basin (Donbas) and the northern
Caspian region in the north to the Mountainous Crimea and the Greater Caucasus in the south is considered. This territory
embraces the southern margin of the East-European craton and the northern periphery of the Tethys Ocean, which originated
in the Neoproterozoic, as well as its marginal seas till the formation of the modern Azov-Black Sea and Caspian basins. 相似文献
