摘　　要：通过最新的下冶铝土矿生产勘探资料,发现下冶铝土矿连续存在厚度大于50m的厚大铝土矿矿体,结合矿区地质、见厚大矿体钻孔含矿岩系特征、见厚大矿体钻孔基本分析结果进行比对分析。认为济源下冶铝土矿勘查找矿中厚大矿体成因,一般厚大矿体出现在C2b1层铁质黏土岩沉积比较薄或缺失的地段。Based on the latest production and exploration data of Xiaye bauxite,it was found that there are continuous thick and large bauxite ore bodies with a thickness greater than 50m in Xiaye bauxite.Combined with the geological conditions of the mining area,the characteristics of the ore bearing rock series in the drilling of thick and large ore bodies,and the basic analysis results of the drilling of thick and large ore bodies,a comparative analysis was conducted.It is believed that the exploration of the Xiaye bauxite mine in Jiyuan has identified the origin of thick and large ore bodies in the mine.Generally,thick and large ore bodies occur in areas where the C2b1 layer of iron clay deposits are relatively thin or missing.
