| 摘 要： | 金峒岔金矿可划分为五个成矿阶段。黄铁矿中的Pb、Bi、Te是矿床的标型元素,其含量越高黄铁矿的含金性愈好。金主要为裂隙金,多赋存在破碎状黄铁矿中。由于Au、Bi、Pb都是大原子量元素,并位于同一周期,故自然金和微粒方铅矿(0.01～0.04毫米)或自然金和粗粒方铅矿(1～2毫米)、碲铋矿系同时结晶,并充填在黄铁矿的裂隙中。

| Abstract: | The gold mineralization of the Jintongcha gold deposit consists of 5minerogenetic stages. Pb, Bi and Te in pyrite are the typomorphic elem-ents of the deposit, the more Pb.Bi and Te the in pyrite are the more goldcontents in it. The gold occurs. mainly in cracks of fractured pyrit.Because Att, Pb, Bi are all the larger atomic Weight elements and arearranged in the same period in atomic period table with the similar che-mical properties, so the native gold and the micro-grained galena(0.01-0.04mm) or the native gold, the coarse-grained galena(1-2mm)and the tellurbismuthite were simultaneously crystallized and were filledof in pyrite cracks. |
