Overview

The Nature and Origin of Granite by W.S. Pitcher

The granitic rocks outcrop abundantly throughout the continents, often forming the cores of mountain chains, and their nature and origin has intrigued earth scientists for hundreds of years. Now that we know that granites for the most part are produced by melting in the deep crust, their appearance in the upper crust provides a way of sampling these otherwise inaccessible depths - not only to learn of the composition of this crustal understory but how it was constructed through time. There is still much to discover, especially concerning the physics and chemistry of the complicated processes of granite generation, and it is the purpose of this book to highlight the existing enigmas.

Table of Contents

1 The historical perspective: an ever changing emphasis.- 2 The categories of granitic rocks: the search for a genetic typology.- 3 Granite as a chemical system: the experimental impact.- 4 The physical nature of granitic magmas: a case of missing information.- 5 The evolution of the granitic texture: a continuum of crystal growth.- 6 Differentiation in granitic magmas: zoning as an example of multifactorial processes at work.- 7 The volcano-plutonic interface: not Read’s hiatus.- 8 The evidence for restite: unmixing as an alternative hypothesis.- 9 The mingling and mixing of granite with basalt: a third term in a multiple hypothesis.- 10 Appinites, diatremes and granodiorites: the interaction of ‘wet’ basalt with granite.- 11 Controls of upwelling and emplacement: the response of the envelope: balloons, pistons and reality.- 12 On the rates of emplacement, crystallization and cooling.- 13 Oceanic plagiogranite: rarely seen but genetically important.- 14 Cordilleran-type batholiths: magmatism and crust formation at a plate edge.- 15 Intraplate magmatism: mainly the A-type, alkali feldspar granites.- 16 Migmatites: are they a source of granitic plutons?.- 17 The waning stages: the role of volatiles in the genesis of pegmatites and metal ores.- 18 The sources of granitic magmas in their various global tectonic niches.- 19 A kind of conclusion: a search for order among multifactorial processes and multifarious interactions.
