基　　金：四川攀枝花地区1:5万新坪、普威、永兴、盐边、麻陇(G47E006023、G47E006024、G47E007022、G47E007023、G47E007024)5幅区域地质矿产调查”子项目(工作项目编号:1212011220395)。

摘　　要：本文对扬子陆块西缘的攀西地区米易县麻陇乡境内的一套基性侵入岩体中的角闪辉长岩取样做LA-ICP-MS锆石U-Pb测年,获得的(910±16)Ma年龄代表该岩体形成于晋宁早期,探讨了岩体的地质意义及与矿化的空间关系,以期对区域古构造格局及大地构造演化以及区域找矿勘查有所裨益。In this paper,the Yangtze landmass miyi county hemp in panxi region of gansu township in the western margin of Angle of a set of basic intrusive mass benefly long rock sample do LA-icp-ms zircon U-Pb dating,the Ma age(910-16)on behalf of the rock mass formed in the early jinning,probes into the geological significance of the rock mass and relation with mineralization space,in the hope of ancient tectonic pattern and tectonic evolution of regional and regional prospecting exploration benefit.
