摘要
广西武宣石叠水泥用灰岩矿位于广西武宣县桐岭镇,为一大型水泥用石灰岩矿床。矿床赋存于上石炭—下二叠统马平组地层中,岩性为浅灰色中厚层状生物屑微晶灰岩夹少量白云岩。矿石质量稳定,为单一的Ⅰ级品。通过对矿区地质特征及矿床成因的论述,分析了矿床沉积环境及成矿物质来源的演变过程,认为广西武宣石叠水泥用灰岩矿属浅水开阔台地型浅海相生物化学成因沉积碳酸盐矿床。
Wuxuan Shidie Limestone Deposit is located in Tongling Town,Wuxuan County,Guangxi.It is a large limestone mine for cement.It occurs in the upper Carboniferous Lower Permian Maping formation,and its lithology is light gray medium thick bedded bioclastic microcrystalline limestone with a small amount of dolomite.The ore quality is stable,and it is a single grade I product.Based on the discussion of geological characteristics and genesis of the deposit,the evolution process of sedimentary environment and material source of the deposit is analyzed.It is considered that the limestone ore of Wuxuan Shidie Cement Deposit in Guangxi belongs to the shallow water open platform type shallow marine biochemical sedimentary carbonate deposit.
