江西宁都县火麻斜稀土矿地球化学特征

Petrogenesis and Mineralization of Huoxiema Granites in Ningdu,Jiangxi Province

通过1:50000矿产地质调查,在江西省宁都县火麻斜一带花岗岩风化壳中发现了稀土元素矿。综合研究认为该区花岗岩形成的构造环境为同碰撞-后碰撞环境,花岗岩的原岩为变泥质岩。花岗岩为稀土矿提供了原生物质。

Through 1:50000 mineral geological survey,Rare-earth deposits were found in the weathered crust of granite in Huoxiema area of Ningdu county,Jiangxi Province.Based on comprehensive studies,it is concluded that the tectonic environment of granite formation in this area is the syn-collision to post-collision environment,and the original rocks of granites are metamorphic argillitic rocks.Granite provides primary materials for rare earth minerals.
