在博格达山东段利用原生晕地球化学研究的方法,对一些成矿元素的原生晕进行了分析与评价。成矿元素定量分析结果表明,Cu、Zn、As等3种元素在研究区为强富集元素,Pb、Co为富集元素;多元统计分析显示主成矿元素Cu与Zn、Pb具有较强的相关性,其相关系数分别为0.544、0.416,R型聚类划分出的Cu-Zn-Pb,Hg-Cr-Au组合代表与铜矿化有关的亲硫、中温环境;单元素具有水平分带性,以单元素异常下限值和陆壳克拉克值为划分标准,圈定了4个Ⅲ级化探异常带,并根据原生晕元素富集赋存特征、组合特点及空间分布特征,初步评价认为研究区Cu-Pb-Zn-Cr-Au-Hg多元素叠加异常为找矿有利地段。
The primary halo of some ore-forming elements was analyzed and evaluated by the method of primary halo geochemistry in the eastern part of Bogda. The results of quantitative analysis of ore-forming elements show that Cu, Zn, As and other three kinds of elements are strongly enriched elements in the study area while Pb and Co are enriched elements. Multivariate statistical analysis shows that the main mineral elements Cu and Zn, Pb are strong The correlation coefficients are 0.544 and 0.416, respectively. The Cu-Zn-Pb and Hg-Cr-Au combinations classified by R-type clustering represent the sulfur- and intermediate-temperature environments related to copper mineralization. Based on the single element anomalous lower limit value and continental crust value, we divided 4 Ⅲ geochemical anomaly bands. According to the characteristics of primary element accumulation, the characteristics of assemblage and the spatial distribution, the preliminary evaluation It is considered that the multi-element superposition of Cu-Pb-Zn-Cr-Au-Hg in the study area is favorable for prospecting.
