摘要
徽县孙家沟金锑矿大地构造位于秦祁昆造山系-秦岭弧盆系-泽库前陆盆地,属岷县鹿儿坝-两当广金坝金汞锑成矿带内崖湾-大桥锑金成矿带的东延(五级成矿带)。区域地层复杂、构造发育,岩浆岩活动强烈,成矿地质背景良好,成矿条件有利。在总结成矿地质背景、地球化学特征的基础上,提出了找矿标志,为今后地质勘查提供一定的参考。
The Sunjiagou gold antimony ore deposit in Huixian County is located in the Qinqi-Kun orogenic system,Qinling Arc basin and Zeku foreland basin,it belongs to the east extension of Neiyawan-Daqiao antimony gold metallogenic belt of Luerba-Liangdangguang Jinba gold ore-forming belt in Minxian County(Grade 5 metallogenic belt).The formation is complex,the structure is developed,the magmatic rock activity is strong,the metallogenic geological background is good,and the metallogenic conditions are favorable.On the basis of summarizing the ore-forming geological background and geochemical characteristics,the prospecting mark are put forward to provide some reference for the future geological exploration.
