Abstract
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.
