【摘要】 隐伏硫化物矿体在地下水的作用下,在其覆盖层浅部含铁锰氧化物和有机质的土壤中形成盐晕。通过对盐晕形成机理及其提取方法的研究,在已知隐伏矿体上方获得了清晰的盐晕异常,且比光谱全分析结果所获异常衬度大。试验结果表明,在我国湿润气候带的平原覆盖区,用盐晕找矿是可行和有前景的。更多还原

【Abstract】 Saline Halos are often formed in the soil containing Fe and Mn oxides and organic material by a concealed sulfide ore body under the action of the ground water. Through a detail study on their formation mechanism and extraction method, distinct saline halo anomalies over some known concealed ore deposits were obtained. Test results indicate that the saline halo method is feasible and has good prospects in mineral prospecting over the flat moist regions of our country.更多还原
