摘要
新疆木垒县大石头一带石灰岩矿体赋存于上石炭统祁家沟组地层中,所圈定的5个石灰岩矿体,长266~3800m,宽30~476m,厚33~387.65m,区域上矿体规模较大。矿石的矿物成分主要为微晶方解石,矿床的平均品位CaO 52.65%、MgO 0.46%、K_(2)O 0.116%、Na_(2)O 0.084%。矿石自然类型为含生物碎屑微晶灰岩,工业类型为水泥、电石用灰岩,矿床成因类型为海陆交互相沉积矿床。
The limestone orebodies in Dashi area of Mulei county,Xinjiang are located in the Qijiagou formation of the Upper Carboniferous.The five limestone orebodies delineated are 266-3800 meters long,30-476 meters wide and 33-387.65 meters thick.The scale of the orebodies in the region is large.The mineral composition of the ore is mainly microcrystalline calcite,and the average grade of the deposit is CaO 52.65%,MgO 0.46%,K_(2)O 0.116%and Na_(2)O 0.084%.The natural type of the ore is microcrystalline limestone containing biological fragments,the industrial type is cement and calcium carbide limestone,and the genetic type of the ore deposit is a marine and land cross sedimentary deposit.
