Granite Genesis: In-Situ Melting and Crustal Evolution

Granitic rocks are a major component of the continental crust and the many and complex problems of their origin that have confronted geologists for over 200 years still are presenting challenges today. Current ideas of granite formation involve lower crustal melting, segregation, ascent (as dykes or diapirs) and emplacement in the upper crust.

In this book we suggest an alternative model for the origin of granite in terms of in-situ melting-intracrustal convection that physically determine...
