WebbAuthors: P. D. Asimow; M. M. Hirschmann; M. S. Ghiorso; E. M. Stolper. Abstract: Batch melting of ascending mantle can be approximated as an isentropic process, since on the time scale of melting heat flow into or out of source regions will typically be negligible and the process is slow enough to be close to reversible.
