摘　　要：宁陕县某金矿地处秦岭中段南坡山地,金矿体主要赋存在燕山期NE-NNE向破碎蚀变带内的破碎蚀变岩及石英脉体中。目前,该矿正处于勘查阶段,只进行了基本的地质工作,研究程度较低。本文采用激电中梯测量和1:10000土壤化学测量圈定矿体后,通过钻探验证、槽探揭露、地质测量、取样分析等工作,查明金矿地质特征,分析成矿地质条件和矿床形成机制,概括矿物富集规律和找矿标志,为后期外围探矿和深部找矿提供真实可靠的理论依据。The XX gold deposit is situated on the southern flank of the central Qinling Mountains,,and the gold ore body mainly exists in the fractured altered rocks and quartz veins in the NE-NNE trending fracture alteration zone of Yanshan Age.At present,the mine is in the exploration stage,only the basic geological work has been carried out,and the research degree is low.In this paper,after the ore body was delineated by IP midladder survey and 1:10,000 soil chemical survey,the geological characteristics of the gold deposit were ascertained,the metallogenic geological conditions and deposit formation mechanism were analyzed,the mineral enrichment rules and prospecting indicators were summarized through the work of drilling verification,channel exploration,geological survey and sampling analysis,so as to provide a real and reliable theoretical basis for the later peripheral prospecting and deep prospecting.
