安徽丁香地区滑脱拆离构造特征及成因浅析

本文探讨了丁香地区滑脱拆离构造的几何学、运动学特征，并初步厘定该地区的滑脱拆离属于江南古陆北侧、长江以南整体滑覆－剥离断层体系的后缘位伸带及中间过流带之部分。文章把丁香地区滑脱拆离构造划分出下伏系统。四个滑脱拆离层系及四个主滑脱拆离面和八个次滑脱拆离面。结合区域地质发展史，还对滑脱拆离构造的成因及其演化做了讨论。

SIMPLE ANALYSES ON CHARACTERISTICS AND GENESES OF DECOLLEMENT AND DECOUPLE STRUCTURES IN THE DINGXIANG AREA

The geotectonic and kinetic characteristics of decollement and decouple structures in the Dingxiang areahave been studitvi, and the author has drawn a conclusion that the decollement and decouple structures system belongs tothe back margin stretching belt and part of tlie middle transitional belt between the Jiangnan paleo-continent and theYangtze River.The decollement and decouple structures of Dingxiang area have been divided into one underlying system,four decollement and decouple layer systems,four main decollement and decouple planes and eight Subordinate decolle-ment and decouple planes.Combining with the regional development,the forming conditions andevolution of the decolle-ment and decouple structu res have also been discussed.
