徐州大洞山水泥灰岩矿床地质特征及成因探讨

Discussion on the Deposit Geological Features and Genesis of Cement Limestone Ore in Dadongshan,Xuzhou

大洞山水泥用石灰岩矿床是海相碳酸盐岩型沉积层状矿床,矿层赋存于中寒武统张夏组—上寒武统崮山组下段,属滨海—浅海相化学和生物化学沉积的混合产物。矿床规模特大,矿层厚度稳定,矿石质量较好,是优质的水泥原料。

Dadongshan cement limestone ore deposit is marine carbonate type of sedimentary deposits. The ore deposit occur in the middle cambrian Zhangxia group-upper cambrian Gushan group at its lower paragraph, belong to chemical and biological chemical deposition of product mix of coast sea-shallow sea phase. The scale of deposit is super-large and thickness is stable and the mineral quality is good, is a high quality cement raw materials.
