摘　　要：甘肃省天水市营房金矿床位于西秦岭北段多金属成矿带李子园金矿田内,矿体赋存于天子山二长花岗岩外接触带的丹凤群地层中,严格受北西向断裂构造控制。结合多年勘查和研究经验,文章总结了营房金矿矿床和矿体地质特征,分析了北西向断裂构造+岩浆作用联合控矿因素,梳理了两条主矿体工程控制程度,并提出主矿体深部、主矿体上盘平行带、控矿断裂北西延伸以及天子山岩体内等四处找矿方向,为后续勘查和生产提供了借鉴。The Yingfang gold deposit in Tianshui City,Gansu Province is located in the Liziyuan gold field of the polymetallic mineralization belt in the northern section of the Western Qinling Mountains.The ore body occurs in the Danfeng Group strata in the outer contact zone of the Tianzishan monzonite,and is strictly controlled by the northwest trending fault structure.Based on years of exploration and research experience,the article summarizes the geological characteristics of the Yingfang gold deposit and ore body,analyzes the combined control factors of northwest trending fault structures and magmatism,sorts out the degree of engineering control of two main ore bodies,and proposes four prospecting directions,including the deep part of the main ore body,the parallel zone of the hanging wall of the main ore body,the northwest extension of the control fault,and the Tianzishan rock body,providing reference for subsequent exploration and production.
