(中南工业大学地质系;长沙; 410083)

摘 要: 本文在进一步改进关键性实验技术的基础上,利用快速淬火高压釜系统成功地完成了四个系列的含水卤化物介质-花岗质岩浆体系中钨锡的流-熔分配实验。确定了一批钨锡流-熔分配系数;并建立了它们与卤化物摩尔浓度之间的线性关系式;分析了氯、钠、氟、钾对钨锡流-熔分配的影响;指出传统的钨锡岩浆期后热液成矿模式值得修正。

Abstract:Based on the further improvement of some crucial experimental techniques,4 series of W,Sn partitioning experiments between granitic melt and halide-bearing aqueous fluid were successfully conducted in RQV (rapid quenched high-pressure vessel system). A lot of F-M partitioning coefficient were determined and some linear equations between it and mole concentration of halide were established as well. The effect of Cl,Na,F and K on the W, Sn partitioning is discussed also. It has been concluded that it would be necessary to modify the classic model of post-magmatic hydrothermal mineralization of W and Sn.

 

Key words: W Sn fluid-melt partitioning; experimental method; granitic magmatic mineralization
