| 摘 要： | 泥潭冲金矿床为主要受近EW向脆-韧性剪切带控制的砷金矿床,是龙王江锑砷金成矿区最具代表性和经济意义的金矿床.文章阐述了矿床地质特征,探讨了载金矿物毒砂的标型特征和金的赋存状态,认为毒砂中的"不可见金"主要为纳米级微粒状的自然金.

| Abstract: | Nitanchong gold deposit was mainly controlled by nearly EW trending brittle-ductile shear zone. It is not only the typical representive, but also the economic gold deposit in Longwangjiang Sb,As, Au metallogenic belt. This paper briery explained the metallogenic geological characteristic and Au occurrence. The gold-bearing mineral are discussed. It is considered that invisible gold mainly occurred in arsenopyrite as nanometer micro-size native gold. |
