金山店杂岩体含金性研究──重砂微金测试应用

ON GOLD-BEARING NATURE OF COMPLEX ROCK IN JINSHANDIAN──APPLYING TRACE ANALYSIS OF GOLD TO HEAVY SAND

分析了岩体构造发育情况，测定了含小金片岩石样品的矿物组成及其含量，并对岩样、重砂样以及尾矿样共２４件样品进行了微金测试，根据宏观的主要控矿条件和微观的矿化信息对金山店杂岩体的含金性作出了评价，为重砂与地球化学相结合的分析方法提供了一个例证。

This paper analyses the development of rock matrix structure,determines mineral compositions and contents of rock samples with small piece of gold, and gives microgram gold test on 24 pieces of rock,heavy sand and tailing samples.On the basis of major ore-controlling macro-condition and mineralization micro-information,gold-bearing nature of the complex rock in Jinshandian is evaluated,which has furnished an illustration to the analysis combining heavy sand with geochemistry.
