摘要
本文所称中国东部是指贺兰山、龙门山及康滇地轴以东地区。在这个范围之外,本文涉及地区国内有川西、滇西的一部分,国外有苏联远东的沿海省、朝鲜、日本、加里曼丹西北部和中南半岛东部,这些都属于亚洲东部大陆边缘和西太平洋岛弧区。
In this paper are discussed:(1)the pre-Indosinian Basement of East China and the main effect of the Indosinian orogeny;(2)types and development of the Mesozoic and Cenozoic basins and(3)the relation between basin formation and the development of continental marginal tract in different stages.The Indosinian Movement brought about the final coagulation of the old massifr in East Asia as a result of the mutual convergence of the opposite continental margins between them.The convergent crustal consumption zones thus formed are(1)the Suolun.Xilamulun zone between the Siberian and North China platforms formed in late Hercynian stage,(2)the Fengxian-Shanyang zone between the latter and the Yangzi Platform,and(3)the Changshan Indosinian zone between the Yangzi Platform and the Indosinian Massif,both of Indosinian age.The giant arcuate Indosinian Belt thus formed in SE Asia has its apex near the Hainan Island,with the Indosinian proper in the west and the SE Chinese coastal zone right to the Akyoshi zone of SW Japan as its two wings.Since the coalescence of East Asia into a concrete whole after the Indosinian orogeny,the main tectonic grain had transferred from NE(Cathaysian)to NNE(Neocathaysian).
