| 摘 要： | 深源流体是一种源于深部的高温高压流体，它富含Ｃｌ－、ＣＯ２、Ｓ２－等矿化剂。金矿床的形成过程是：深源流体从深部沿高渗透断裂带向上运移过程中，从含金岩体中活化出金而形成含金流体。在含金热流体中，Ａｕ主要以ＡｕＣｌ－２、ＡｕＣｌ－４、ＡｕＳ－２、ＡｕＳ－３、ＡｕＳＯ３－３等形式迁移。当含金流体进入有利的成矿环境中，与围岩发生强烈的交代作用。在交代过程中，金的络合物分解，从而导致金矿床的形成

| Abstract: | The deep fluid is a fluid of high temperature and high pressure from the depths, which contains a great quantity of mineralizers such as Cl -,CO 2 and S 2- . The gold metallogenic process is as follows. The deep fluid activates Au from the Au bearing bodies to be formed Au bearing fluid as it moves up along the intense permeable fault zone from the depths. In the Au bearing fluid, Au moves mainly as AuCl - 2,AuCl - 4,AuS - 2 ,AuS - 3 and AuSO 3- 3. The Au bearing fluid replaces strongly with wall rocks when it moves into ore forming environments. Au complex ions are resolved in replacement and enriched into the gold deposits. |
