The granitic rocks outcrop abundantly throughout the continents often formingthe cores of mountain chains and their nature and origin has intrigued earthscientists for hundreds of years. Now that we know that granites for the mostpart are produced by melting in the deep crust their appearance in the uppercrust provides a way of sampling these otherwise inaccessible depths not onlyto learn of the composition of this crustal understory but how it wasconstructed through time. There is still much to discover especiallyconcerning the physics and chemistry of the complicated processes of granitegeneration and it is the purpose of this book to highlight the existingenigmas. «
