摘要
攀枝花-西昌地区位于扬子板块的西南缘。文章运用地体学说,根据断裂、沉积建造、岩浆活动和地球物理等标志的地体解析方法,将其划分为六大地体。并探讨了晋宁期以来,各地体拼合和离散的历史。研究表明该区在地质历史中构造面貌是不断变化的,是一典型的拼贴构造。
The Panzhihua-Xichang region in the west of Sichuan is located on the southwesternmargin of the Yangtze Plate. In the region,according to the differences in sedimentary strata,boundary faults,magmatism and geophysical data, six terranes can be divided, namely Yanyuanterrane,Huidong terrane, Yanbian terrane, Mianning terrane,Xichang terrane and Songpan-Ganziterrane. The amalgamation and dispersion history of these terranes since Jinning stage have beenstudied. The geological history of the region can well be explained by the collage tectonics.
