Streaming of saline fluids through Archean crust: Another view of charnockite-granite relations in southern India

The complementary roles of granites and rocks of the granulite facies have long been a key issue in models of the evolution of the continental crust. “Dehydration melting”, or fluid-absent melting of a lower crust containing H2O only in the small amounts present in biotite and amphibole, has raised problems of excessively high temperatures and restricted amounts of granite production, factors seemingly incapable of explaining voluminous bodies...
