摘要:
介绍了金属活动态的理论依据、成晕机制及提取方法,并应用金属活动态提取法在大兴安岭原始森林 覆盖区对已知矿进行试验研究,发现在高寒森林覆盖区,利用金的水提取态异常强度低,异常不明显,而金的粘 土结合态和铁锰氧化物结合态异常清晰地反映在矿体上方,异常强度居于中等。金的有机质结合态异常值虽然 高,但容易受有机质在样品中颗粒大小等因素的影响而使异常出现多个峰值。总之,利用金属活动态提取法在 高寒森林覆盖区进行找矿可以快速有效地确定异常,但要注意排除过多有机杂质在提取过程中的影响。
Abstract:
The selective leaching of mobile metal forms(MOMEO)is used on exploration for concealed mineral deposits in forestry terrain, Daxing’anling Mountains, Heilongjiang Province. The soil samples are subjected to MOMEO processing for selective leaching of four forms of gold: water-extractable gold, absorbed and exchangea- ble gold, organically bound gold and occluded gold in iron and manganese oxides. The results show that these four forms of gold can give indication to the concealed gold ore body. It is found that the anomalies of the water- extractable gold are not clear, but that of the absorbed and exchangeable gold and the organic bound gold are pretty good. It is also found that though the intensity of the organically bound gold is high enough, the anomalies of it is not stable due to the great dimensions of the organic molecule, which is difficult to be filtered through. In one word, the method of MOMEO in high cold forestry terrain can be used to explore the anomalies quickly and efficiently, but the influence of too much organic during the process of the extracting should be excluded.
