The Geology And Mapping Of Granite Batholiths (lecture Notes In Earth Sciences)

E-Book Overview

This book is a practical guide for field geologists. Consequently it deals mainly with the physical attributes of granites as encountered in the field. However, granites have always been a focus for controversy, the nature of which has changed as the science has evolved, but which has been essentially concerned with the nature and origin of granites of every kind. This work is published at a time when modern experimental work seems to be close to resolving these fundamental questions. Nevertheless its prime purpose is to portray the astonishing variety of granite phenomena as seen by the field geologist.

All field geologists work initially at the scale of the outcrop, consequently most of the phenomena treated herein are those which are visible at outcrop scale. However, granites typically occur as plutons and batholiths, some of which are so large as to apparently defy any effort at systematic treatment. Having had the opportunity of mapping two very large and very different batholiths, namely the Coastal Batholith of Peru and the tin granites of Southeast Asia, I have found that it is possible to map large batholiths within a relatively short time, so that the geology of the batholith as a whole can be appreciated. Moreover batholiths are one of the most common modes of granite occurrence, so it makes sense to study them at their natural scale. During my working life I have worked with many geologists from underdeveloped countries and this book is mainly to help them in unravelling the geology of their native batholiths. I have been lucky with my friends and colleagues of many
