一、矿区地质概况本区位于康滇地轴东部。次级隆起的南缘。隆起与凹陷间以一东西向深断裂为界。断裂以北普遍分布着前震旦纪昆阳群,断裂以南则以震旦纪至中生代的地层为主。断裂线上尚见有海西期辉长岩、辉绿玢岩及玄武岩出露。本文拟述之铜矿床是赋存于上震旦统底部的沉积中——受改造矿床。矿层的产状平缓,倾角一般为10—30°。其下覆之昆阳群褶皱强烈,倾角
First, the geological overview of the mining area This area is located in the eastern part of the axis of Kang Dian. Secondary uplift of the southern edge. Between the uplift and depression to an east-west deep fault as the boundary. Pre-Sinian Kunyang Group is generally distributed to the north of the fault, and strata from the Sinian to Mesozoic dominated the south of the fault. There are still seen on the fault line Hercynian gabbro, gabbro rock and basalt exposed. The copper deposit proposed in this article is a sedimentary-altered deposit hosted in the bottom of the Upper Sinian. Gentle formation of the mine, the inclination is generally 10-30 °. The Kunyang group under the folds of the folds, dip angle
