摘要
本文计算出1m～3mNaCl体系.温度为100～500℃条件下CO_2、CH_4、H_2、CO、N_2、H_2S和SO_2亨利常数,以及上述成分在100～350℃时的分配系数和气、液平衡常数.并设计出矿物包裹体中水溶气体的lgfo_2—T、lgf_(co)-T、lgf_(co)-T和lgf_(co)-pH等物理化学参数图,解析了江西茅坪锡矿床中石英和锡石的矿物包裹体形成的物理化学条件.
The author has calculated the Henry constant of CO2, CH4, H2, CO, N2, H2S and SO2 in 1m, 2m and 3m NaCl systems at temperature 100℃ ~ 500℃, and the distribution coefficient and gas-liquid equilibrium constant of the composition mentioned above at 100℃-350℃, and has made physicochemical parameter figures of logfo2~T, logfco2-T, logfco-T and Iogfco2-pH etc. in water-soluble gas within mineral inclusions. The physicochemical condition forming the inclusions in quartz and cassiterite from Maoping tin deposit was successfully interpreted by using the figures.
