Geological Characteristics and Genesis of Crystal Graphite Deposit in Baitaigou East,Subei Country

本文介绍了甘肃肃北白台沟东晶质石墨矿的矿体特征、矿床规模、成因等。白台沟东晶质石墨矿赋存于敦煌岩群B岩组2岩段中的二云石英片岩中,严格受层位控制。矿体呈层状、似层状展布,矿体规模为小-大型,全区固定碳平均品位3.20%,石墨片径>100目的占54%以上,工业类型为晶质石墨。为层控型的沉积-变质矿床。

This article introduces the geological characteristics,orebody characteristics,orebody origin and so on of the crystalline graphite ore in Subei Baitaigou east,Gansu Province.Baitaigou east crystalline graphite ore is stored in the two-cloud quartz shale in the section 2 of group B of Dunhuang rock,which is strictly controlled by the horizon.A layered and layered ore body is distributed,the size of the ore body is small-large,the average grade of fixed carbon in the whole area is 3.20%,and the size of sheet diameter>100 mesh accounted for more than 54%,and the industrial type is crystalline graphite.It is a layer-controlled sedimentary-metamorphic deposit.
