内蒙古鲁根浑迪铅锌多金属矿地质特征及找矿方向

Geological characteristics and prospecting directionthe of Lugenhundi Pb-ZNpolymetallic deposit.

鲁根浑迪铅锌多金属矿区位于哲斯—林西复向斜(Ⅲ级)北东段,黄岗梁—甘珠尔庙成矿带内,成矿与近EW向、NE向断裂及硅化、绿泥石化、黄铁矿化关系密切。矿床成因类型为中温热液充填交代硫化物型。综合分析矿区成矿地质背景、地表及深部矿化蚀变特征、地球物理及地球化学特征,认为该区浅部以锡为主,中深部以锌为主,有较好的找矿前景,对下一步开展地质找矿具有一定的指导意义。

Lugenhundi Lead-Zinc polymetallic metallogenic deposit is located at thenortheastern section in Zhesi-Linxi( L3)synclinorium,which is located within Huanggangliang-Ganzhuermiaometallogenic belt. Ore-forming is related closely with near EW and NE direction faults,silification,chloritization and pyritization. Genetic type of this deposit belongs to medium thermal filling sulfide deposit type. Through a comprehensive analysis of metallogenic geological background,characteristics of mineralization of the surface and deep areas and alteration,geophysical and geochemical characteristics,this paper indicated that this deposit’s surface part is dominated with Tin,the middle-deep part is abundant with Zinc. The exploration prospect is desirable,which provide certain practical guiding significance for the next step geological prospecting work.
