Abstract—

An equation system of an olivine-silicate melt liquidus thermobarometer has been obtained by processing the sampling set of 772 experimental equilibria of olivine crystals with basic melts by multidimensional statistics methods. The equations reproduce the experimental data with a small error in a wide basic composition range (from komatiites to dacites) at a temperature of 1040–1500°С and a pressure of 1–30 kbar. According to the thermobarometer testing results, the deviation of the calculated liquidus temperatures from experimental values does not exceed ±3°C in most of the temperature range.

液相线热压计的开发，以模拟橄榄石-熔体平衡

摘要—

通过使用多维统计方法处理具有基本熔体的772橄榄石晶体实验平衡的采样集，获得了橄榄石-硅酸盐熔体液相线温度晴雨表的方程组。这些方程式可在1040–1500°С的温度和1–30 kbar的压力下，在较宽的基本组成范围（从科马铁矿到dacites）中再现实验数据，并且误差很小。根据热压计测试结果，在大多数温度范围内，计算出的液相线温度与实验值的偏差不超过±3°C。
