Abstract
A liquid miscibility occurs within the Quaternary system, Na_2O-Al_2O_3-SiO_2-CO_2 between Na_2 CO_3-rich liquids and NaAlSi_3O_8-rich liquids. The vapor-saturated liquidus surface does not intersect the miscibility gap at low pressures, but with increasing pressure it undergoes two discontinuous shifts toward the CO_2 apex of the tetrahedron, produced by carbonation reactions in the system Na_2O-SiO_2-CO_2. These position changes cause the vapor-saturated surface to intersect the miscibility gap. At 1 kilobar pressure on the join NaAlSi_3O_8-Na_2CO_3-CO_2, the two-liquid field occurs at temperatures above 870 degrees C.
