| 摘 要： | 西伯利亚地台西南缘加里东褶皱系中，金矿床发育有两种建造类型：a.金-硫化物-石英建造：b.金-矽卡岩建造。它们形成于古岛弧的地动力学构造环境，一般位于蛇绿岩建造带中，成因上与原地型深成花岗岩类岩体有关。矿石的伴生元素有Cu、Pb、Zn，丰度值一般高于围岩10-20倍。As、Sb、Mo、W、Bi、Te等元素可作为工业矿体之标志性元素。

| Abstract: | There are two kinds of gold-deposit formations within Caledonian foldsystem in the southwest of Siberian platform: a. Gold-sulfide-quartz formation; b. Gold-skarn forma tion. They are formed in geodynamic tectonic surroundings of ancient island arc, usually oc-cured in the zone of ophiolitic formation and related with proto -plutonic granitoid rocks in genesis. Associated elements of the ore, Cu, Pb and Zn, are 10-20 times as much as that of wall rocks. As, Sb, Mo, W, Bi and Te etc. may act as indicator for industrial orebody. |
