摘　　要：河南光山县云山寨水泥用大理岩矿赋存于古生界寒武系刘山岩组(∈_(3)l)地层中,矿体呈层状、似层状产出。矿石中CaO平均品位51.68%,品位变化系数5.16%,品位稳定,矿床规模为大型。本文总结了云山寨水泥用大理岩矿矿床赋存层位,矿体特征。通过综合分析其地质特征,确定该区大理岩矿成因为海相沉积变质型矿床,以期为寻找可供进一步开发利用的大理岩矿提供数据支撑。The cement-grade marble ore in Yunshanzhai,Guangshan county,Henan province occurs in the strata of the Liushanyan Formation(∈_(3)l)of the Paleozoic Cambrian System.The ore bodies are distributed in layers or strata-like forms.The average grade of CaO in the ore is 51.68%,and the coefficient of grade variation is 5.16%.The grade is stable,and the scale of the deposit is large.This paper summarizes the occurrence horizons and the characteristics of the ore bodies of the Yunshanzhai cement-grade marble ore deposit.Based on a comprehensive analysis of its geological characteristics,it is determined that the genesis of the marble deposits in this area is of the marine sedimentary metamorphic type,with the expectation of providing data support for the search for marble deposits that can be further exploited and utilized.
