Study on Genesis of Gold Deposit and Mineralization Enrichment Regularity Based on Mapping Analysis

For gold exploration and sustainable exploitation, it has great significance for the genesis of gold deposit mineralization enrichment regularity. Jiaodong area is one of the most important gold producing areas in China, whose reserves account for about 1 /3 of proven rock gold reserves in China. In this paper, we take northwest of Jiaodong gold concentration area, the eastern side of Yishu fault zone and Xincheng fault structure zone as the main research object to obtain the zircon U-Pb age of the Linglong granite and guojialing granodiorite, which is 158.53 + 0.79Ma and 135.56 + 0.53Ma. On the basis of the general analyzing research of the spatial variation law of ore controlling structure, the dynamic characteristics of ore controlling faults, the spatial location mechanism of industrial ore-bodies and other mineralization enrichment regularity, the analysis shows that there is another mineralization enrichment section in the deep part of the mining area. Namely, the dip angle of the fracture where occurrence tend to be gently is a favorable region for mineralization, that is the second mineralization enrichment segment, whcih provides theoretical basis for the next step of prospecting work.
