水系沉积物测量在蒙古发现弘戈尔斑岩铜金矿床

Discovery of the Khongor Porphyry Cu-Au Deposit in the Gobi Desert, Mongolia by A Low Density Stream Sediment Survey

超细粒度(-250目)水系沉积物测量是国际上新兴的水系沉积物采样方法,具有控制流长长和汇水盆地面积大,发现异常概率高的特点。低密度超细粒水系沉积物测量在蒙古戈壁沙漠4×104km2勘探区(亚洲金矿),获得一批金铜水系沉积物异常,直接发现弘戈尔斑岩铜金矿床。在弘戈尔斑岩铜金矿和亚甘热液型金矿进行了水系沉积物采样方法试验,总结出一套戈壁沙漠地区,超细粒水系沉积物测量的采样方法。

This paper deals with discovery of the Khongor porphyry Cu-Au deposit in the Gobi Desert, Mongolia by a low density stream sediment survey. Stream sediment survey sampling method test in the Gobi Desert is made in Khongor porphyry Cu-Au prospect and Yagan epithermal Au prospect.
