摘　　要：大尹格庄金矿床位于胶东地区招平断裂带中段,为典型的破碎带蚀变岩型矿床。本文通过1:10000构造填图修测工作,进一步了解工作区地质构造特征和成矿地质条件,建立起研究区构造格架。大尹格庄矿床外围以北东向,北西西向断裂为主。与成矿关系最为密切的是招平断裂,带内蚀变发育,主要为绢英岩化、黄铁绢英岩化、钾化(硅钾化)。招平断裂带中段填图区南北段蚀变带存在一定差异,北段蚀变带西侧钾化较强,南段蚀变更加强烈,黄铁矿化、褐铁矿化较强。Dayingezhuang gold deposit is located in the middle of Zhaoping fault zone in Jiaodong area,and it is a typical altered rock deposit in fracture zone.In this paper,through 1:10000 structural mapping and repair work,we further understand the geological structure characteristics and metallogenic geological conditions of the working area,and establish the structural framework of the study area.The outskirts of the Dayingezhuang deposit are oriented northeast,with northwest westward faults predominant.The most closely related to mineralization is the Zhaoping fault,where alteration is developed in the zone,mainly sericinization,pyrite sericinization,and potash(silicon potash).There is a certain difference in the alteration zone between the north and south sections of the mapping area in the middle section of the Zhaoping fault zone.The western side of the northern section alteration zone has stronger potashification,the southern section has more intense alteration,and the pyrite mineralization and limonite mineralization are stronger.
