| 摘 要： | 在综合前人研究成果的基础上，根据幔热柱和板块构造理论，本文提出了晚古生代扬子板块西缘-构造活动新模式，认为幔热社活动与扬子板块在二叠纪的顺时针旋转共同造成了峨眉山玄武岩的时空分布特点，该观点也解释了攀西裂谷为何提前“夭折”的问题。

| Abstract: | On the basis of previous studies, a new thermotectonic model has been proposed for the westrn margin ofthe Yangtze plate in Late Paleozoic. Time-space zoning in Emeishan basalts was caused by a mantle plume and theclockwise rotation of the Yangtze plate in the Permian. This viewpoint is helpful for us to understand why the us to Undersand why thePanxi rift died out ahead of time. |
