内蒙古黑山头地区银多金属矿地质特征及找矿潜力

Geological Features and Prospecting Potential of Silver Polymetallic Ore in Heishantou Area, Inner Mongolia

工作区位于得尔布干斑岩钼矿-浅成低温热液型铅锌银金矿床成矿带上,通过地质工作区内已发现4条银矿化蚀变带。通过对工作区的地质特征、地球化学特征、地球物理特征及矿产检查成果进行分析,认为该区具有形成次火山热液型和浅成低温热液型矿床的优越条件,与该成矿带上同类型矿床的对比,发现黑山头地区具有较好的成矿银多金属的找矿潜力,建议在矿化和蚀变较好地段投入物探工作,以圈定矿体规模及走向。

The working area is situated on the Derbugan porphyry molybdenum ore deposit-epithermal lead, zinc, silver and gold ore deposits metallogenic belt. 4 silver mineralized alteration zones have been found in the area through geological works. The authors have carried out analyses on geological, geochemical, geophysical features and mineral inspection works, considered that the area has provided with favorable conditions to form subvolcanic hydrothermal and epithermal ore deposits. Through comparative study of same type ore deposits on the metallogenic belt, initially discussed metallogenic potential in the Heishantou area, thus can guide further prospecting works.
