| 摘 要： | 基于石英包裹体成分测定、容矿断裂形成机制的理论分析、高温高压实验研究、动力学数学公式举例、含金流体瞬间就位过程及容矿断裂形成环境的探讨 ,提出了幔源含金流体主动就位机制。幔源流体萃取围岩金质并由导矿构造进入容矿断裂过程中 ,依自身扩张力或贯入力使岩石发生破裂 ,容矿断裂的产生和含矿流体沉淀近于同时形成。这为金矿脉与基性 -超基性脉岩的关系、金矿脉在空间呈有规律性分布和建立模式的研究增加了新的内容。

| Abstract: | The mechanism of positive emplacement of mantle gold bearing fluid is proposed on the basis of the composition of quartz inclusions,theoretical analysis of forming mechanism of ore controlling struc tures,high T,P experiments and dynamic mathematical formulae,instantaneous emplacement of gold bearing fluid and forming setting of ore controlling structures.The mechanism makes the mantle gold bearing fluid precipitating at the same time.The mechanism sheds light on the relationship be tween gold veins and basic ultrabasic rocks.Moreover,the gold deposit distribution law and the metal logenetic model have been established. |
