摘要
内蒙古阿拉善左旗大疙瘩山一带水泥用石灰岩矿多赋存于中-下奥陶统天景山组地层中,多为单斜厚-巨厚层状产出,覆盖层少,基岩基本裸露,地表出露良好。本文对内蒙古阿拉善左旗大疙瘩山水泥用石灰岩矿床的构造、矿体特征、矿石类型、矿石质量及夹石等特征进行了分析,并对矿床成因进行了阐述。
The limestone ore for cement in dagedun mountain area of Alxa Left Banner,Inner Mongolia mostly occurs in the Tianjingshan formation of middle lower Ordovician,mostly in monoclinic thick thick thick layer,with few overburden,basically bare bedrock and good surface exposure.This paper analyzes the structure,ore body characteristics,ore type,ore quality and stone inclusion of dagedoushan cement limestone deposit in Alxa Left Banner,Inner Mongolia,and expounds the genesis of the deposit.
