摘要

@@ In 1992, Lower Permian reefs were found in various stratigraphic sections in such counties as Ganluo,Puge, and Butuo, in Xichang Basin. This discovery not only promotes the development of Lower Permain sedimentology in Xichang Basin, but also is of great significance for oil-gas exploration along the western margin of Yangtze platform.
