摘　　要：柯家村熔剂用碳酸盐矿区隶属东至县洋湖镇及葛公镇。矿区出露奥陶系下统仑山组上段及红花园组下段地层,岩性主要为细中晶白云岩、中粗晶白云岩、粗晶白云岩及微晶灰岩,矿层厚度大,质量稳定,是化工、冶金、建材等行业的优质原料。文章结合前期地质勘查结果,根据矿体特征、规模、矿石矿物成分、矿石自然类型及成因分析,认为该矿床属碳酸盐岩台地边缘浅滩相与开阔台地相交替沉积成因类型矿床。该研究为矿区后续勘查开发提供借鉴。Kejiacun dolomite and limestone mine for flux belongs to Yanghu town and Gegong town,Dongzhi county.The upper Lunshan formation and lower honghuayuan formation of the lower ordovician are exposed in the mining area.The mainly lithology is finely grained dolomite,mesocrystalline dolomite,macrocrystalline dolomite and micrite.Based on the results of previous geological exploration,according to the characteristics,scale,mineral composition,natural type and genesis analysis of ore body,this paper believes that the deposit belongs to the alternate sedimentary genesis type deposit of carbonate platform edge shoal facies and open platform facies.This study provides reference for the follow-up exploration and development of the mine.
