| 摘 要： | 粤西推覆构造带总体沿罗定－云浮－清远－英德一线展布，ＮＥ－ＮＮＥ走向，呈一向ＳＥ突出的弧形，长达３５０ｋｍ，由ＮＷ向ＳＥ推覆，水平推覆距离大于４０ｋｍ。推覆构造的外来系统为前震旦系、震旦系和寒武系，原地系统为泥盆系和石炭系。它形成于海西－印支期，燕山期又经历了强烈的构造运动、大规模的岩浆活动及白垩纪内陆盆地的沉积作用。后期的剥蚀作用，导致构造窗发育。这是一个经历了强烈改造的同碰撞型巨型逆冲推覆构造

| Abstract: | The NE-NNE trending western Guangdong nappe zone extends along LuodingYunfu-Qingyuan-Yingde for 350 km, forming an arc bending towards the southeast.It was thrust from northwest to southeast with a distance of more than 40 km.The allochthon consists of the Presinian, Sinian and Cambrian system.The autochthon comprises the Devonian and Carboniferous system.It was mainly formed in the Hercynian and Indosinian epoch, and underwent strong tectonism movement, magmatism and sedimentation in the Yanshanian movement.Subsequent erosion caused the development of structural windows.It is a large strongly modified syn-collision nappe zone. |
