Vapor-absent partial melting of amphibolite/eclogite at 8-32 kbar: Implications for the origin and growth of the continental crust.

摘要

Partial melting experiments were carried out on four natural amphibolites over a range in temperatures and pressures (1000-1150;Comparison of the experimental residual assemblages with lower crustal garnet-granulite xenoliths in kimberlites suggests a continuance of chemical trends between the two sources of data. The generally lower temperatures (600-900
