昆中断裂带南北陆块基底、盖层沉积、岩浆岩对比研究——昆中断裂带构造意义的讨论
A comparative study of the basement, the sedimentary blanket and the magmatic rocks of the south and north landmasses in the middle Kunlun fault belt: the tectonic significance of the middle Kunlun fault belt
摘要
Abstract
Based on 1-250000 regional geological survey in a blank area of northern Tibetan Plateau, the authors studied the middle Kunlun fault belt in such aspects as structure properties and rock types, geochemistry and sources of the basement metamorphic rocks (including the meta -basic volcanic rocks and metapelite), cover sedimentary rocks, Precambrian felsic intrusive rocks, and mafic-ultramafic intrusive rocks. The results show that the north and south sides of die Kunlun fault zone is completely different in continental lithosphere, sedimentary rocks, crust and mantle structure, physical properties and geochemical composition. It is thus suggested that the East Kunlun orogenic belt is actually a land mass of the collision between two continental-margin orogenic complexes. Therefore, the north land mass and the south land mass did not belong to the same land mass in Proterozoic, and the middle Kunlun fault was exactly the boundary between Eurasia and Gondwana land.关键词
