摘要
本文通过大量的地质资料,详细论述了拉拉铜矿黄铁矿的产状及结晶习性,黄铁矿的硬度,晶胞参数;反射率,化学成分及微量元素特征,并以此与典型矿床中黄铁矿标型特征对比,认为本矿床黄铁矿主要为火山喷气沉积作用的产物,少量为后期变质作用形成。
This paper deals with the pyrite crystal habit, hardness, unit cell parameter, reflective power, chemical composition and microelement feature of the pyrite of Larlar copper deposit in different periods. In comparison with the pyrite character of the typical deposit, it is suggested that most pyrites in Larlar copper deposit have formed by volcanic exhalative-sedimentary processes, only a few pyrites related with metamorphism.
