Mixtures of synthetic crystalline enstatite and diopside were reacted with small water contents in sealed capsules in piston-cylinder apparatus at 30 kb between 1000~ C and 1700 ~ C. The compositions of coexisting enstatite and diopside solid solutions were measured with an AI~L-EMX electron micropr
Density measurements have been carried out on the melt system diopside-anorthite from room temperature to 1600 ~ C at 1 atm, and from 1400 ~ C to 1800 ~ C at pressures up to 20 Kb. The densities were determined based on the dilatometric curve and density at 22~ for lowtemperatures, the double-bob Ar
