通过在穆卡拉地区进行1：5万土壤地球化学测量，总结区内出露的地层、岩性、构造等地质特征，运用土壤地球化学方法进行找矿研究。元素地球化学参数统计显示，Zr、Bi、Au、Pb、Mo元素含量相对较高，变异系数较大，易参与次生富集作用，形成地球化学异常；元素分布型式显示，Ti、Ag、As、Co、Au、Cu、Bi、Mo分布广泛，离散度大，尤其是Cu元素呈显著的多峰分布，次生富集趋势强烈；因子分析、聚变分析多方统计分析表明，Cu、Ag、Au、As元素代表主要成矿元素的次生富集组合，可作为本区主要的找矿指示元素。

By conducting soil geochemical surveys work in scale of 1:50000 in mucarra area, the geological features of the stratum, lithology and structure are summarized. On this basis, with the soil geochemical prospecting methods, the researches get the following understanding:1)the statistic parameters of elements show that Zr、As、Co、Au、Cu、Bi and Mo element contents are relatively high, while their coefficients of variation are relatively large, and they can enrich to form geochemical anomaly easily;2)element distribution patterns show that Ti 、Ag、Co、Au、Cu、Bi and Mo elements have wide distribution range and large dispersion, while the Cu elements present a significant multimodal distribution and strong trend of secondary enrichment;factor analysis, cluster analysis and correlation analysis show that Cu、Ag、Au、As elements can represent the secondary enrichment combination of the main ore-forming elements;3)They can be used as the main prospecting indicator elements.
