根据新的苏联东部及其邻区构造图,对具不同时代陆壳或花岗-变质岩层地区的沉积盆地作了结构和岩层成分的分析。强调指出,沉积盆地与处于不同演化阶段的构造有关。发现在地质结构、时代和沉积岩层类型以及油气形成条件等方面,在西部地块的盆地和东部滨洋地块的盆地之间,具有本质的差别。在每个地块中,距太平洋盆地最远的那些位于外部的盆地,具有最大的面积和有利的沉积条件。
According to the new tectonic map of the eastern part of the Soviet Union and its neighboring areas, the structural and stratigraphic compositions of the sedimentary basins in different areas of the continental crust or granite-metamorphic strata are analyzed. It is emphasized that the sedimentary basins are related to the structures at different stages of evolution. It is found that there is an essential difference between the geological structure, the age, the type of sedimentary rock formation, and the conditions of oil and gas formation between the basins in the western block and those in the eastern oceanic block. In each block, the outermost basins furthest from the Pacific Basin have the largest area and favorable deposition conditions.
