Equilibrium compositions of diopside-jadeite pyroxene coexisting with albite and quartz were experimentally determined at 25 different P-T conditions, using an electron microprobe for analysis. The new data and the 600°C data of (1983) provided the following mixing properties of the diopside (Di)-jadeite (Jd) solid solution (J, K): G xs = X Jd X Di [12600 - 9.45 T + (12600 - 7.6 T )( X Jd - X Di ) - (21400 - 16.2 T )( X Jd - X Di ) 2 ]. The Di-Jd solution is close to ideal above 1000°C but immiscible below 565°C. The Di-Jd solvus is slightly asymmetric with the crest at composition Di 42.4 Jd 57.6 . Excess enthalpy is positive but smaller than indicated by the enthalpy of solution measurements of et al. (1980). Disorder in the Di-Jd solution is significantly smaller than complete disorder implied by the ionic two-site model.
