摘要
岩矿鉴定是矿床研究的重要辅助性学科,促进矿床学研究向更深层次的研究发展。岩矿鉴定以矿物类型、含量、标型矿物以及矿石组构等为基础,获取不同的物理化学参数,进而分析整个成矿过程。本文以某铜矿床为例,结合2件光片鉴定,其矿石矿物中有黄铜矿、闪锌矿、铜蓝等,提出黄铜矿和黄铁矿晚于磁铁矿形成,黄铁矿早于闪锌矿、黄铜矿形成的认识,为该区域找矿勘查工作提供了参考。
Rock ore identification is an important auxiliary subject of deposit research,which promotes the research of deposits to a deeper level of research.The rock ore identification is based on mineral type,content,standard mineral and ore composition,etc.,to obtain different physical and chemical parameters,and then analyze the whole mineralization process.Taking a copper deposit as an example,combined with 2 pieces of light identification,the ore minerals have chalcopyrite,sphalerite,covellite etc,this paper puts forward that chalcopyrite and pyrite later than the formation of magnetite,pyrite earlier than sphalerite and chalcopyrite ore formation,for the region to provide a reference for prospecting for prospecting.
