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 determines the process from partial melting of mid-upper crustal rocks to formation of a convecting magma...

Petrogenesis of Metamorphic Rocks presents a large number of diagrams showing the stability relations among minerals and groups of minerals found in metamorphic rocks. The diagrams help to determine the pressure and temperature conditions under which a given set of metamorphic rocks may have formed. Other parameters that control metamorphic mineral assemblages are also discussed and pitfalls resulting from simplifications and generalizations are highlighted. The book discusses the most common metamorphic rock types, their nomenclature, structure and graphical...
