古太平洋板块中生代俯冲活动与南海中生界
|
摘要
中国大陆东部边缘发育的中生代混杂岩增生带、中侏罗世末期以来形成的NE—NNE向构造格局以及大规模岩浆活动形成的NNE向火山岩带等地质构造特征揭示,中生代发生了古太平洋板块向中国大陆东部边缘NNW向的俯冲活动。位于南海东部的厚层残余中生界揭示了与此同时南海广泛的沉积作用。此次研究结果证实,南海东部的中生界并非是中特提斯海的东向延伸,而是西太平洋构造域的组成部分。
All the evidence,such as the Mesozoic mélange zone,the NE-NNE trending tectonic pattern formed since middle-Jurassic,and the volcanic zone in NNE direction caused by strong magmatic activities along the eastern margin of China continent,suggests the tectonic event of subduction of the Mesozoic Pacific Ocean Plate under the eastern margin of China continent.The thick remnant of Mesozoic may reveal the general sedimentation pattern of the South China Sea in Mesozoic.This paper tries to prove that the Mesozoic deposits in the eastern South China Sea belong to the western Pacific tectonic domain rather than the eastern extension of the middle-Tethys.
