摘要
In this paper, the distribution, Late Quaternary activity, deep structure and formation mechanism of Longquanshan fault zone are discussed. It’s possible that the north segment section of Longquanshan fault zone is distributed along the west side of Lonquanshan Mountains at east of Deyang City. The fault emerges in both wings of anticline on the middle segment of the fault. And the south segment of the fault is mainly W-dipping. The fault has been active since Late Pleistocene. The previous terrace investigation demonstrated that the fault zone even actived in Holocene is deserved to be done.
