摘要:

用金属活动态提取法在广西与山西黄土区进行试验研究,发现在山西黄土区,利用金的水提取态含量偏 低,异常不明显,而金的粘土结合态、有机物结合态和铁锰氧化物结合态异常清晰地反映在矿体上方;而在雨量 充沛的广西红壤区,金的水提取态和铁锰氧化物结合态异常较好,而粘土结合态金异常效果不太理想。研究结 果表明在这两个地区应用金属活动态测量法进行找矿研究时,可以对其提取有利的相态来进行靶位确定。

Abstract:

The selective leaching of mobile forms of metals(MOMEO) is used in the comparative exploration between red earth terrain of Guangxi Zhuang Autonomous Region and the loess terrain of Shanxi Province. It is found that the anomalies of the water extractable gold are not clear in the loess terrain of Shanxi Province, but that of the absorbed and exchangeable gold and occluded gold in iron and manganese oxides is pretty good there. On the other hand, it is found that the anomalies of the water extractable gold and the occluded gold in iron and manganese oxides are better in the red earth terrain of Guangxi Region, but the absorbed and exchangeable gold is not ideal. In a word, when using the method of MOMEO in these two terrains, different leaching of gold forms should be selected to apply for searching ore body.
