| 摘 要： | 大比例尺填图和构造解析表明,马家河坝断层是发育于地台内部的一个小型逆冲断层,可分为5个带:前缘逆冲叠瓦带、中部剪切滑动带、东缘斜向逆冲走滑带、西缘斜向正断走滑带及后缘构造变形带。喜山期持续的区域应力作用使那里沟背斜SE翼沿软弱面断裂,经递进扩展变形,最终形成逆冲推覆构造。

| Abstract: | The Majiaheba fault is considered as a small thrust fault in the interior area of platform through large-scale geological mapping and tectonic analysis.The Majiaheba thrust fault can be divided into 5 zone:front zone with forethrusting and compression,central zone with shearing and sliding,east zone with thrusting and shoving,the west normal fault zone with shoving and the trailing deformation zone.The SE limb of Naligou anticline was fractured in the action of persistent regional stressing and expanded into detachment-thrust structure during Himalayan orogenic period. |
