摘　　要：河南省崤山东部银多金属矿集区位于豫西崤山黄土覆盖区,目前已发现中河和老里湾两处大型隐伏银多金属矿床,具有较好的找矿前景。近几年,河南省地质矿产勘查开发局第一地质矿产调查院在该区相继开展了大量的地质和物化探工作,但由于大面积的厚黄土覆盖,对区内的成矿条件、控矿因素、成矿规律及找矿预测等方面的研究较少,对该区的下一步找矿方向及工作带来了一定的困难。本文通过分析区域成矿地质条件,根据已有的地质、物探和化探等资料,结合已发现的两处银多金属矿床特征,优选出对本区找矿有重要指示意义的4类控矿要素,即构造、岩体、物探和化探异常区。利用Surpac三维建模软件,建立了各控矿地质要素的三维实体模型,并运用三维信息量法提取三维成矿有利信息,根据成矿有利信息的大小,在已知矿区的深部和外围覆盖区圈定了9个找矿靶区,为下一步矿产勘查工作提供了有力的依据。The silver polymetallic ore concentration area in the eastern Xiaoshan Mountain of Henan Province is located in the loess covered area.At present,two large hidden silver polymetallic deposits in Zhonghe and Laoliwan have been found with great potential.In recent years,a great deal of research work had been carried out on the geological,physical and chemical exploration by the first bureau of geology and mineral resources survey in these area have carried out a lot of geological and physical and chemical exploration work,but due to the large area of thick loess cover,in the area of metallogenic conditions,ore control factors,metallogenic law and prospecting prediction research is less,the next step of the prospecting direction and work has brought certain difficulties.In this paper,by analyzing the metallogenic geological conditions of the region,according to the existing geological,geophysical and geochemical data,combined with the characteristics of the two silver polymetallic deposits,select the four types of ore control elements with important indicator significance for prospecting in this area,namely structure,rock mass,geophysical and geochemical anomaly areas.Using surpac software,established the control geological elements of 3 d solid model,and using the three dimensional information,according to the size of the metallogenic information,in the known mining area of deep and peripheral coverage delineated nine prospecting target area,for the next step of mineral exploration work provides a powerful basis.
