摘　　要：对岩子脚金矿床黄铁矿矿物学、化学成分与金矿化关系的研究表明:早中期形成的黄铁矿颜色较深,颗粒较粗,金矿化较好;而晚期形成的黄铁矿粒径较小,不含金。总趋势是粒度愈粗含金量愈高。含金黄铁矿表现为S亏损、As偏高。According to the study on relationship between mineralogy,chemical analysis of pyrite and Au metallogenesis of Yanzijiao Au deposit,The color of pyrite formed in earlier time is deeper,grain coarser and Au metallogenesis better,whereas the later ones are smaller and without Au.And the general trend is the grain coarser the Au content higher.The Au-bearing pyrite shows S depletion,whereas As somewhat higher.
