中国东部的含科石英榴辉岩带的发现——郯庐断裂平移作用的证据

THE DISCOVERY OF A COESITE-BEARING ECLOGITE BELT IN EASTERN CHINA

摘要: 根据近年来在中朝板块与扬子板块碰撞带上,所发现的科石英或含科石英假象的榴辉岩,推测中国东部的郯庐断裂的左行平移幅度可达550km,活动时代在中生代之后。

Abstract: According to the coesite-and coesite pseudomorph-bearing eclogite belt discovered recently in a collision zone between the Sino-Korean and Yang- tze plates,it is inferred that the amplitude of the sinistral strike-slip dis- placement of the Tancheng-Lujiang fault in eastern China may attain 550 km and that its movement took place after the Mesozoic.
