摘要

Daliangshan tectonic zone is the rhombic area east of the Anninghe and Zemuhe fault zones, southeast of the Tibetan Plateau. The Daliangshan tectonic zone is enclosed by three tectonic units: the Bayan Har terrane in its northwest, the Yangtze Platform in its southeast and the Longmen Mountain-Yanyuan nappe tectonic belt in the middle. The Daliangshan Fault zone is the most important fault zone in the Dalianshan tectonic zone.This fault zone, together with the Anninghe fault zone and the Zemuhe Fault zone, make up of the middle part of the Xianshuihe-Xiaojiang fault zone. The Daliangshan fault zone consists of 4 branches: the Shimian-Yuexi Fault, the Puxiong Fault, the Butuo Fault and the Jiaoji River Fault.
