摘要：
The Weiyuan anticline formed in Cenozoic. At the end of Oligocene, NW-SE-direction compression made the Qianwei-Anyue basement fault in the southeast slope of the Leshan-Longnusi paleo-anticline move inversely so as to form the Laolongba-Weiyuan fault-propagation-type anticline. At the beginning and the end of Pleistocene, SW-NE-direction compression made the Muchuan-Yongjin and Yaan-Yibin basement fault move inversely to cut the above anticline into the Laolongba anticline and Weiyuan anticline. From the point of view of tectonic trap, prospecting for gas should aim at the anticline nearby in which moderate faults develop.
