| 摘 要： | 已有文献认为:空穴型黄铁矿的存在对金成矿有利。作者对二道沟金矿床的研究表明,金矿化程度不仅与黄铁矿的热电性有关,而且与黄铁矿的晶体形态关系十分密切。富矿体中黄铁矿晶体形态复杂,种类多并以五角十二面体为主,叶夫济科娃晶体形态得分值(XFeS_)高;含矿较贫或不含矿的岩体黄铁矿晶体形态简单,种类少并以立方体为主,叶夫济科娃晶体形态得分值(XFeS_2)低。

| Abstract: | It has been considered that hole-type pyrite contributes to ore forming. The paper studies Erdaogou gold deposits, as a result that the degree of gold mineralization not only relates to the thermoelectricity of pyrite but also the change of crystal form: in high-grade orebodies, the crystal forms of pyrite are complex and various, mainly in pyritohedron, and XFeS_2 high;in low-grade orebodies, they are simple and few, mainly in cube, and XFeS_2 low. |
