| 摘 要： | 大铜厂铜矿位于会理断陷盆地,产于中生代白垩世小坝组砂、砾岩地层中,是砂砾岩型铜矿床的典型代表.通过对常、微量元素,稀土元素,稳定同位素及碎屑物等特征分析,发现矿石与围岩具有明显的同源性,显示成矿物质主要来源于地层建造,远端矿源为摩挲营花岗岩体和龙帚山玄武岩体.同时综合其他成矿特征,对矿床成因做出简要分析.

| Abstract: | The Datongchang copper deposit lies in the Huili fault basin and is a typical sandstone type copper deposit and confined to Cretaceous sandstone and conglomerate.The study of major elements,microelements,REE,isotope compositions and detrital minerals indicates that the ore and the wall rock are congenetic and ore material was derived mainly from the host strata including the basalt and granite. |
