摘要：

中国大陆是从泛大洋中存在的一些陆核发展起来的。中国海的大地构造演化与欧亚、太平洋和印度洋三大板块之间的相互作用密切相关,可分成五个阶段:前寒武纪,陆核形成并发展为稳定块体或克拉通;古生代,块体逐渐联合成统一的中国大陆;晚三叠—早白垩世,大陆受到强烈挤压与改造;晚白垩—渐新世,板块边缘聚敛而欧亚板块东部扩张;晚渐新世以来,菲律宾海板块在欧亚板缘俯冲和中国东部沉降,形成中国海的现代形态。

Abstract:

The recongnization of this paper is based upon the geological and geophysical studies of the China seas and their adjacent regions in the past 30 years.The China mainland was developed from some continental cores existing in Pantha lassa and unit-ed as a whole in the Late Paleozoic.The tectonic evolution of the China seas is closely related to the in-teractions among Eurasia,Pacific and Indian oceanic lithosphere plates.It can be divided into 5 stages:1)An ∈,the continental cores formed and developed into blocks or cratons;2)Pz,blocks gradually united as a whole;3)T3-K1,the China mainland was strongly compressed and remaked;4)K2-E2,the margins of plates converged and the interior of the eastern part of Eurasian plate spreaded;5)After E33,the subduction occurred at the margin of Eurasian plate and its interior was widely subsided,and formed today's feature of the China seas.
