山东五莲七宝山多金属矿红石岗矿段Cd，Ga等分散元素的富集规律研究

本文对红石岗矿段的Ⅰ-1,Ⅰ-2号银铅锌共生矿体利用详查、补充详查工作部分坑道、钻探工程样品的副样进行了微量元素分析。结果表明其中的Ga和Cd元素超过了伴生组分要求,其分布与主组分分布基本一致,利用spss软件对各元素之间的相关性进行分析,Ga元素和Ge元素,Cd元素和Zn元素极强相关;Tl元素和Ga元素,In元素和Fe元素,Cd元素和Pb元素强相关。Zn/Cd比值显示该矿床为中低温矿床,这与前人的研究结论是一致的。In主要赋存在黄铁矿中,Cd主要赋存在闪锌矿中、方铅矿次之,Tl和Ga具有较强的共生关系。闪锌矿中Cd可能主要以类质同象形式存在。

Study on Enrichment Law of Dispersed Elements Ca and Ga in Hongshigang Ore Section of Qibaoshan Polymetallic Deposit in Wulian County of Shandong Province

In this paper,the trace element analysis is carried out on the tunnel and drilling duplicate samples in HongshigangⅠ-1 ore block,Ⅰ-2 silver-lead-zinc ore body.As showed by the result,the distribution of gallium and cadmium exceeds the upper bound of the associated components and is basically consistent with that of the principal components.SPSS software is used to analyze the correlation between each element.Ga element and Ge element,Cd element and Zn element are extreme strongly correlated.Tl element and Ga element,In element and Fe element,Cd element and Pb element are strongly correlated.As showed by the ratio of Zn to Cd,the deposit is a low and medium temperature deposit,which is consistent with the previous research conclusions.In element occurs mainly in pyrite,Cd occurs mainly in sphalerite,and followed by galena.Tl and Ga have a strong symbiotic relationship.Cd in sphalerite may exist mainly in the form of isomorphism.
