二门大理石矿床位于鄂尔多斯拗陷区和汾渭地堑断陷区之间,属于韩城-永寿隆起区。矿体赋存于上寒武统崮山组。通过对该矿床进行的1:2000地质勘查和综合研究,按岩石颜色、花纹、结构构造等将矿体划分为9个矿层,矿石划分为三大类型10个品种;分析了矿石的岩石化学成分,进行了抗压,抗折等一系列物理性能实验;探讨了矿床开采的水文地质条件和综合利用的途径。
The Ermen Marble deposit is located between the Ordos Depression and the Fenwei Graben Fault Depression and belongs to the Hancheng-Yongshou uplift. Ore bodies occur in Upper Cambrian Dangshan Formation. According to the 1: 2000 geological prospecting and comprehensive study of the ore deposit, the ore body is divided into nine ore layers according to rock color, pattern and structural structure, and the ore is divided into three types and 10 varieties. The rock chemical composition , Carried out a series of physical properties such as compressive and flexural resistance experiments; discussed the hydrogeological conditions of mining and comprehensive utilization of ways.
