乌力沟金矿位于甘肃省肃北县盐池湾乡。大地构造属中南祁连山弧盆系之党河南山—拉脊山弧间裂谷;秦祁昆成矿域南祁连加里东期Cu-Pb-Zn-Ag-Gr-石棉带党河南山加里东期Au-Cu-Pb成矿带。矿床赋存于乌力沟二长花岗岩侵入体的内、外接触带中,矿床严格受NWW向断裂带构造控制,矿化带长2 000m,矿体在矿化带中具有分段赋存特征,矿床中成矿元素具中、低温元素富集特征。该矿床是党河南山地区继贾公台、黑刺沟后,又一新的找矿突破,初步分析属中低温热液作用下形成的蚀变岩型金矿床,对该矿床地质特征的讨论,有助于推动该区金矿勘查工作。
Wuligou gold mine is located in Salt Lake Bay Township, Subei County, Gansu Province. The earth structure belongs to the Central South Qilian Mountain arc basin party Henan mountain - ridge ridge arc intergranular rift; Qin Qikun metallogenetic area South Qilian Caledonian Cu-Pb-Zn-Ag-Gr- asbestos belt party Nanshan Caledonian Au- Cu-Pb metallogenic belt. The deposit is hosted in the inner and outer contact zones of the Wuligou monzonitic granite intrusive body. The deposit is strictly controlled by NWW fault zone. The mineralized zone is 2 000 m long and the orebodies have segmental occurrence in the mineralized zone The ore-forming elements in the deposit are characterized by elemental enrichment at medium and low temperature. This deposit is a new exploration breakthrough after the Jiaghantai and Heichougou in the Henan Shan area. A preliminary analysis is made of altered rock type gold deposits formed under the effect of medium- and low-temperature hydrothermal fluids. The geological characteristics of this deposit are discussed , Help to promote gold exploration in the area.
