从东海石油地质工作的重要进展看西太平洋大陆边缘新生代盆地的构造演化——一种海沟向洋后退的残余弧后盆地的演化模式

中国所在的亚洲,是全球地质结构最复杂的一个洲.这里不仅有若干小地块与巍峨造山带形成的镶嵌组合,还有以沟、弧、盆并行发育的长达近20000km的现代大陆边缘.中国地质学家,以黄汲清、朱夏院士作代表,先后以"多旋回"、"3个构造域"(古亚洲、滨太平洋及特提斯—喜马拉雅)和"东西两条锋线"等简明的概括,对中国地质构造以大陆内部为主的内涵,进行了深邃的阐述.在他们的影响之下,力图以简介东海石油地质进展为契机,在"海沟向洋后退和残余弧后盆地"思想下,对西太平洋大陆边缘的构造演化及盆地发生规律,作一个尝试性的探讨,并以此来纪念黄汲清院士诞辰100周年. 

RETHINKING ABOUT THE TECTONIC EVOLUTION OF THE CENOZOIC CONTINENTAL MARGINAL BASIN OF THE WEST PACIFIC OCEAN IN ACCORDANCE WITH SOME IMPORTANT ADVANCES OF STUDIES OF PETROLEUM GEOLOGY IN EAST CHINA SEA--AN EVOLUTIONARY MODEL OF RESIDUAL BACK ARC BASINS DE

Asia is the most complicated continent in the view of global geological tectonics. There is not only mosaic structures consisting of small blocks and giant orogenic belts, but also modern continental margin with trenchs, island arc and basins lasting for 20 000 km. Chinese geologists, presented by Academian Huang Jiqing and Zhu xia, elaborated the geological tectonics of China by theories of "polycycle", "three tectonic domains (PaleoAsian, marginal-Pacific and Tethyan-Himalayan tectonic domains)" and "two frontal lines both in west and east". Under the light of their theories, the tectonic evolution of continental margin of west Pacific ocean and the development of basins in the area were studied with the idea of "trench retreating towards ocean and residual backarc basins", which was in accordance with some important advances of studies of petroleum geology in East China Sea.
