内蒙古自治区库伦旗地区石灰岩矿地质特征浅析

Geological characteristics of limestone ore in Kurunqi area,Inner Mongolia Autonomous Region

研究区位于内蒙古自治区库伦旗境内,水泥用石灰岩矿主要产于石炭系上统白家店组地层中,本矿床为石炭系上统的浅海相生物化学沉积的石灰岩矿层。成因属浅海相潮间坪、潮上坪沉积环境下的化学—生物化学沉积成因。研究区内以厚层块状结晶灰岩为主,矿石结构主要有微晶结构、细晶结构、微晶—细晶结构,矿石构造主要为层状构造、厚层状构造。

The research area is located in Coulomb Banner,Inner Mongolia Autonomous Region.The limestone deposits for cement are mainly produced in the Baijiadian formation of the upper Carboniferous,and the deposit is a limestone bed of neritic Marine facies biodeposition in the lower Carboniferous.The genesis belongs to the chemicalbiochemical sedimentary genesis in the sedimentary environment of the intertidal flat of shallow Marine facies and the upper tidal flat.In the study area,the bulk crystalline limestone is mainly thick,and the ore structure mainly consists of microcrystalline structure,fine crystal structure,microcrystalline-fine crystal structure,and the ore structure mainly consists of layered structure and thick layered structure.
