摘　　要：在新疆金窝子金矿区,利用2种深穿透地球化学方法———金属活动态提取方法和电地球化学方法进行对比试验,结果表明这些方法可以在隐伏矿上方有效地发现异常。在干旱荒漠区由于氧化作用和蒸发作用强烈,地表形成氧化地球化学障和大量盐类的蒸发地球化学障,这些地球化学障可以捕获由深部迁移至地表的含矿信息,因此,用深穿透地球化学的铁锰氧化物膜提取和盐类蒸发障良好导电性能的电提取可以有效地指示矿体。A deeppenetrating geochemical research project has been designed to improve the exploration techniques through a comparison of related methods in various concealed deposits. This paper describes the results obtained by the comparison of the Selective Leaching of Mobile Metals (MOMEO) method and the Separatory Electrogeochemistry method at the Jinwozi gold ore district in the desert terrain of Xinjiang. Both the selective leaching of metals occluded in FeMn oxide coatings and the electrogeochemical extraction of ions are effective in indicating concealed deposits in the arid desert terrain. 
