哈得尔甘南地区位于柴达木盆地西南缘,所处大地构造位置在区域上隶属东昆仑岩浆弧带祁漫塔格造山亚带,具有良好的找矿前景.已发现矿体与区域成矿格局和物化探异常不甚相符,经对该区物性资料的分析,结合区域成矿规律,提出了在该区寻找矽卡岩型铁多金属矿的找矿标志和物探工作方法.通过高精度扫面圈定磁异常,在磁异常处布设激电中梯剖面进一步确定异常源,结合磁电异常特征,能够快速圈定铁及多金属矿体在地表的投影位置.对利用物探方法预测的成矿靶区进行深部验证,发现多个矿体,为该区今后的找矿工作提供经验.
Located in the southwestern margin of the Qaidam Basin, the Hadrian-Gannan region has a tectonic position that belongs to the Qimattag Orogenic Belt in the East Kunlun Magmatic Arc Zone, and has good prospecting potential. It has been found that ore bodies and regional mineralization Pattern and geophysical and geochemical anomalies do not quite match.According to the analysis of the physical data in this area and the regional metallogenic regularity, this paper proposed the prospecting signs and geophysical methods of skarn-type iron-polymetallic deposits in this area, Scanning delineation magnetic anomaly, laying an intermediate section of the ladder in the magnetic anomaly to further identify the anomalous source, combined with the magnetic anomaly characteristics, can quickly delineate the projection of iron and polymetallic ore body in the surface of the Earth’s surface.For the prediction of mineralization by geophysical methods Deep verification of the target area and the discovery of multiple ore bodies provide experience for prospecting work in the area.
