化探方法在内蒙古保隆屯南沟银多金属矿区勘查中的应用效果

The application effect of geochemical technique at Baolongtunnangou Ag-polymetallic deposit mining exploration in Inner Mongolia

矿区位于内蒙—大兴安岭地槽褶皱系东南缘的中—晚华力西褶皱带上。2008—2009年地质队先后在该区应用地质、化探、磁法、电法等综合方法,经过1:5万普查、1:1万详查发现了该矿床的物化探异常。经槽探等方法揭露,发现了富含银铅锌的金属硫化物矿体。它们具有一定的规模,值得开展进一步找矿工作,目前正在进行钻孔验证。

Mine area is located in the southeast margin of the Medium - Later Variscan fold belts of Inner Mongolia - Daxinga- nling geosyncline fold system. In the years 2008 and 2009, the geological team applied in the area geological, geochemical, magnetic, electrical and other comprehensive techniques successively, finding geophysical and geochemical anomalies in this mining area through the 1：50000 scale prospecting survey and 1：10000 scale general exploration. Exposed by trenching and other methods, it proved rich in silver - lead - zinc metal sulfide deposit. They have a certain scale, worthy of further exploration work, with ongoing verification drillings.
