摘　　要：郝家湾-圣水塘一带出露地层主要为古元古界黄土窑岩组、新生界第四系,构造主要表现为糜棱岩化韧性变形构造,变质侵入岩呈岩株、岩枝、岩脉等形态产出,岩性有角闪二辉麻粒岩、片麻状二长花岗岩、变质二长花岗岩、变质正长花岗岩等。区内1:5万水系沉积物加密测量圈定Au1、Au2、Au3三个金异常,岩石化探剖面、槽探异常查证结果显示本区地表金矿化较好,找矿潜力较大。The outcrops in haojiawan-Shengshuitang area are mainly the metamorphic rock group of Paleoproterozoic and loess system of Cenozoic.The structure is mainly mylonitization ductile deformation.The metamorphic intrusive rocks occur in the form of strain,branch and vein,and the lithology includes hornblende granulite,gneisses monzogranite,metamorphic monzogranite and metamorphic syenite.Three gold anomalies Au1,Au2 and Au3 were delineated by stream sediment encryption survey in the area.The results of geochemical section and trench anomaly investigation show that the surface gold mineralization in this area is good and the prospecting potential is great.
