摘　　要：文章当中结合实践,对甘肃北山新老金厂一带金矿地层、构造、侵入岩、矿床特征、矿体特征、围岩蚀变进行总结分析,指出老金厂金矿主要分布于甘肃北山南带花牛山地体当中,金矿成矿过程当中有着非常复杂的地质构造环境和十分强烈的构造-岩浆-热液活动,在分析矿床地质特征和控矿因素基础上总结成矿规律,探讨矿床成因,为区内今后金矿找矿工作提供一些借鉴和参考。Combined with practice,this paper summarizes and analyzes the strata,structure,intrusive rocks,deposit characteristics,ore body characteristics and wall rock alteration of gold deposits in the new and old Jinchang area of Beishan,Gansu Province,and points out that the old Jinchang gold deposits are mainly distributed in the huaniu mountain body in the South belt of Beishan,Gansu Province,There is a very complex geological tectonic environment and very strong tectonic magmatic hydrothermal activity in the process of gold mineralization.Based on the analysis of the geological characteristics and ore controlling factors of the deposit,this paper summarizes the metallogenic law and discusses the genesis of the deposit,so as to provide some reference for the future gold prospecting work in the area.
