摘　　要：上泉矿区熔剂用石灰岩矿位于兴业县葵阳镇,为一大型黑色冶金熔剂用石灰岩矿床。为研究矿床地质特征及成因类型,对该矿床进行了详细的地质勘查工作,分析矿床成矿地质条件及沉积环境特征。发现矿床赋存于上石炭统—下二叠统马平组、上二叠统栖霞组地层中,岩性主要为浅灰、灰白色厚层至块状生物屑灰岩、含生物屑微晶灰岩及深灰、灰黑色中厚层微晶灰岩、含硅质团块微晶灰岩,为一浅海开阔台地相碳酸盐岩建造沉积矿床,属生物化学沉积型矿床。The flux limestone mine in Shangquan mining area is located in Kuiyang Town,Xingye County,which is a large-scale ferrous metallurgical flux limestone deposit.In order to study the geological characteristics and genetic types of the deposit,a detailed geological exploration of the deposit was carried out,and the metallogenic geological conditions and sedimentary environment characteristics of the deposit were analyzed.It is found that the deposits occur in the Upper Carboniferous-Lower Permian Maping Formation and the Upper Permian Qixia Formation.The lithology is mainly light gray,gray-white thick layer to massive bioclastic limestone,bioclastic microcrystalline limestone,dark gray,gray-black medium thick layer microcrystalline limestone,and siliceous block microcrystalline limestone.It is a sedimentary deposit of carbonate formation in shallow open platform,belonging to biochemical sedimentary deposit.
