利用雷利奇—孔格修正的状态方程计算了混合的H_2O—CO_2挥发性流体包裹体的总摩尔体积、摩尔分数和CO_2相密度。利用其计算结果作出了若干很有用的P-T图解(CO_2密度固定),并可以用这些图解定性或定量地快速确定H_2O—CO_2(±NaCl)体系;在固相线以上包裹体总等体积线的P-T范围.计算表明,一些太古代绿岩金矿床的高峰期变质压力为3-5 Kb。从本文的研究结果可以看出,对利用过去已发表的有关流体包裹体的研究估算的压力可能需要作重新解释。
The total molar volume, molar fraction and CO 2 phase density of mixed H_2O-CO_2 volatile fluid inclusions were calculated using the state equation of Ricky Ridge-Kongge correction. Some useful PT diagrams (CO 2 density) were made using the results of the calculations. H_2O-CO_2 (± NaCl) systems can be quickly and qualitatively and qualitatively quantified using these plots. For the total volumetric inclusions above the solidus PT range. Calculations show that some Archean Greenstone gold deposits have a peak metamorphic pressure of 3-5 Kb. From the results of this study, it can be seen that the pressure to make use of the previously published studies on fluid inclusions may need to be reinterpreted.
