摘要
四川锦屏造山带主要由锦屏山陆内逆冲-推覆带、前陆逆冲-推覆带和前陆隆起带组成。本文通过分析其构造单元的特征,认为:茶铺子—巴折复活断裂带为分区性边界断层;扬子准地台西缘实为经前震旦纪基底形成之后,继而转化为震旦纪—三叠纪大陆被动边缘,相继卷入中生代碰撞造山,最终在新生代发生陆内造山而成的造山带。
There exist the Jingpin intracontinent thrust nappe belt, foreland thrust nappe belt and foreland uplift belt in the Jinping area, Sichuan. Based on the characteristics of structural units in this area, this paper proposes that the Chapuzi Baze regional revival fault is the regional boundary fault, and points out the Yangtze paraplatform western edge is a thrust fold belt that turns into the continental passive edge in Sinian Triassic Period on the basis of the pre Sinian basement and involves collision orogenesis in Mesozoic Era.
