土壤地球化学找矿试验性研究

黄石狮子立山属于长江中下游铜铁成矿带的一部分,为了更广泛地在本区寻找有一定经济意义的矿产。利用土壤地球化学方法,找出本区成矿指示性元素,为指导本区进一步找矿。研究发现,本区土壤被测12种微量元素(As、Sb、Hg、Co、Sr、Pb、Ba、Mo、Cu、Ag、Zn、Ni)在区域断裂带上或附近出现异常,异常峰值高且宽度大。从其异常特征、异常组合和相关性的分析可知,As、Pb、Ag、Zn、Sb、Mo等元素是寻找本区铅-锌-银等多金属矿床有效的指示性元素;而元素Sr、Ba是天青石、重晶石矿等非金属矿有效的指示性元素。

A TENTATIVE STUDY ON SOIL GEOCHEMISTRY FOR PROSPECTING

The Huangshi region belongs to a part of copper iron metallogenic zone in the mid lower reach of the Yangtse River. In order to look for more valuable and economic deposits in this region, the method of soil geochemistry is used to research the relation between trace elements (As, Sb, Hg, Co, Sr, Pb, Ba, Ag, Zn, Ni) and deposits. The results of analysis on the trace elements show that all of elements appear to be apparently anomalous above a structure or nearby. Furthermore, the statistical correlation analysis, cluster analysis and factor analysis suggest that these elements (As, Pb, Ag, Zn, Sb, Mo) are closely correlative with the polymetallic deposits such as lead zinc silver deposits, and the elements Sr and Ba are closely correlative with the nonmetallic deposits such as the celestite and barite deposits.
