In this article we present the results of some studies of the composition of an aqueous phase in equilibrium with various three-phase assemblages in the system K2O-Al2O3-SiO2 (figure 1) such as quartz-feldspar-muscovite, muscovite-leucite-corundum, and several others. We interpret the results as indicating that the solutes are dominantly uncharged species, specifically alkali-alumina and alkalialumina- silica species.
