| 摘 要： | 对胶东照岛山金矿中黄铁矿成分和热电性标型特征研究表明:黄铁矿成分亏S富As;黄铁矿的特征元素为:As,Co,Ni,Mo,Se,Au,Ag,Sb,Pb,Te,不同成矿阶段微量元素含量的变化说明,黄铁矿的形成温度从早期成矿阶段到主成矿阶段逐渐降低,金沉淀主要发生在石英黄铁矿和多金属硫化物阶段;P型黄铁矿出现率为61%,与胶东几个典型金矿相比,黄铁矿热电系数离散性较大;热电导型按成矿时间先后变化规律为:PN→PN→PN→PN;As是金矿化的有利组分,微量元素As与(Co+Ni)的相对含量与黄铁矿P型、N型出现率及导型组合密切相关。结合黄铁矿成矿温度、热电系数垂向变化以及黄铁矿P型出现率、P型均值分带性等标型特征的研究表明:照岛山金矿床的形成温度为150℃~340℃,属中低温矿床;矿床总体剥蚀较浅,深部矿体未被揭露;P型黄铁矿热电系数均值、出现率高值区是有利的找矿标志。黄铁矿热电性参数显示,矿区南部矿段(8线~16线)和北部矿段(120线)-200 m以下分别存在一处高值区,推测两处具有深部找矿前景。

| Abstract: | Pyrite is one of the most important gold bearing minerals in eastern Shandong gold province.The compositions,crystal form,thermoelectric characteristics and cell parameters and so on were studied to unravel the mechanism of hydrothermal gold deposits.It was showed that the composition of pyrite is characterized by poor in S,rich in As.The typical trace elements same as other places in the eastern Shandong province are comprised by As,Co,Ni,Mo,Se,Au,Ag,Sb,Pb and Te.Average contents of trace elements in pyrit... |
