摘要
通过对焦家金矿床黄铁矿形态、主要成分、微量元素、结构、含金性的分析总结,认为焦家金矿床的成因为中温岩浆热液和变质热液共同作用形成。黄铁矿颗粒中以中、细、微粒含金性较高,随着深度增加,其颗粒变小,金的成色增加,但品位降低。
A systematic study on the typomorphic characteristics in morphotype, principal component, microelement and structure of pyrite has been made in the Jiaojia gold deposit, and it is believed that the origin of the deposit is the combination of moderate temperature magmatic hydrothermal fluid with metamorphic-hydrothermal solution. The gold bearing property of medium-fine grained pyrite is higher. And with the increase of the depth, the grain size is finer, the purity of gold is higher, while the grade of gold is lower.
