A method is described for the determination of silicate melting points to 2000°C and 50 kb, using tungsten | rhenium thermocouples in piston-cylinder apparatus. Pressures are corrected for frictional losses and temperatures for the effect of pressure on the emf of the thermocouple. The melting curve of diopside has been measured to 50 kb; agreement with F. R. Boyd and J. L. England's 1963 data is good to 30 kb, but our results lie at substantially higher temperatures than theirs at the highest pressure. The difference in the two curves amounts to 88°C at 50 kb. Finally, the melting relationship proposed by G. C. Kennedy is examined for these new data.
