A PROBLEM IN MEASUREMENTS OF HIGH PRESSURE MELTING CURVE OF IRON:INFLUENCE OF MELTING MECHANISM ON THE MELTING TEMPERATURE

High pressure melting curve of iron is crucial in modeling the earth′s core.But a system deviation exists between the experimental data of static high pressure experiments and those of the shock wave experiments.With the help of detailed analysis of possible melting mechanism in the two kinds of experiments,we correct the melting data directly from the experimental results and get a self consistent high pressure melting curve of iron.This melting curve indicates the melting temperature of iron at the core/mantle boundary is about 3850K,and 6000K at the inner/out core boundary.This result is also consistent with the recommended value by Anderson.
