摘要
本文用Takenouchi和Kennedy(1965)关于H_2O-Nacl-Co_2体系实验数据进行回归分析,得出该三元系液相中压力(0—1500bar)、温度(100—450℃)、Nacl浓度(0—20wt％)和CO_2溶解度(0—36wt％)之间的函数关系,讨论了用此函数方程计算压力的误差(±2％—±40％,一般小于|±30％|)。对山东玲珑金矿床等一些热液矿床的压力计算表明,所得数值与其他地质压力计测算的结果接近。
A function among pressure (0-2000 bar), temperature (100-450℃), NaCl concentration (0-20wt%) and CO2 solubility (0-36wt%) in liquid for the system H2O-NaCl-CO2 has been obtained by regression analysis from the experimental data given by Takenouchi and Kennedy (1965), and the errors involved in pressure calculation (±2%-±40%, generally less than |±30% | with the equation are discussed. With this equation the minimum ore-forming pressures of the Linglong gold deposit and other hydrothermal ore deposits were estimated, and the values are approximate to those obtained by other geobarometers.
