采用坩埚支撑回路技术，在总压力为1 atm，温度为1300-1470°C的条件下，用碱对具有可变Al 2 O3和SiO2含量的模型硅酸盐熔体进行实验饱和。结果表明，Al_2 O_3含量对硅酸盐熔体K、Na饱和度影响不大。相反，SiO2含量强烈影响硅酸盐熔体中碱金属的溶解度。进行模型计算，以评估碱性和岩浆的污染/混合过程中碱的行为。
Model silicate melts with variable Al2O3 and SiO2 contents were experimentally saturated with alkalis at a total pressure of 1 atm and temperatures of 1300–1470°C, using the crucible supported loop technique. It was shown that Al2O3 content has little influence on the degree of silicate melt saturation with K and Na. In contrast, SiO2 content strongly affects the solubility of alkalis in silicate melts. Model calculations were performed to evaluate the behavior of alkalis during the contamination/mixing of basic and silicic magmas.
