辽西养马甸钼矿原生晕元素的统计分析及其找矿意义

通过对原生晕的统计分析可研究出地球化学元素在成矿中的演化特征,从而为预测、找矿提供有力的依据。文章通过对有关元素的聚类分析、因子分析及轴向分带序列的研究,揭示了养马甸钼矿区内Mo与Au,As的相关性较好,Au和As可以作为找钼的近程指示元素,而Ag对钼的寻找也有一定的指示意义。Ag和Sb的关系表明,Sb对钼的寻找具有一定的远程指示意义。通过轴向分带的研究,结合ZK5地球化学变化曲线可知,ZK5的地球化学参数值于250m左右由升到降,表明了下部隐伏矿体存在的可能。

Statistical analysis of elements in primary halo of Yangmadian molybdenum deposit in the west Liaoning Province and the significance to the ore prospecting

Statistical analysis of the primary halo reveals evolution characteristics of ore elements during mineralization and provides evidence for the ore prediction and prospecting. Cluster analysis, factor analysis and axial zoning sequence study of elements concerned show that in Yangmadian molybdenum deposit Mo, Au,As are better correlated, Au and As are the proximal indicator of molybdenum deposit, Ag is of a certain implication of indication of molybdenum deposit. Ag is correlated to Sb and Sb is a dismal indicator of molybdenum deposit more or less. Axial zoning sequence study of elements and geochemical variation curve of drill hole ZK5 show turning point about 250 m from rising to dropping of geochemical parameter reflecting possible blind ore bodies at depth.
