元素地球化学不活动组分判别--以库布苏金矿中矿带研究为例

本文从探讨元素不活动组分的原理出发 ,利用Gresens(196 7)质量平衡方程及Brimhall等 (1987)提出的元素不活动组分ΔX -fv 图解 ,对复杂热液成矿体系的元素不活动组分进行了深入探讨。指出了复杂体系内部各个子体系间元素不活动组分及体积变化上的差异。并结合实际 ,对库布苏金矿中矿带元素不活动组分进行了研究。同时对一些矿床地质现象的形成及成矿物质来源从元素地球化学角度进行了解释和判断。

ESTIMATION OF IMMOBILE ELEMENTS--AN EXAMPLE IN THE MIDDLE BELT OF KUBUSU GOLD DEPOSIT

On the basis of the theory of immobile elements, making use of Gresens' equation (1967) and immobile composition ΔX|f-v diagram of Brimhall (1987), this paper thoroughly discusses immobile compositions in a complicated hydrothermal mineralization system. It points out the differences in immobile compositions among different sub|systems in the hydrothermal mineralization system, studies immobile compositions in the middle belt of the Kubusu gold deposit, and from the viewpoint of geochemistry presents explanations of some geological phenomena in the deposit and the source of metallogenic materials.;
