This book covers a wide range of processes which govern the properties and evolution of the deep continental crust. The response of rocks to conditions of deep crustal metamorphism and the onset of melting is a fundamental part of large-scale geological history which researchers have only recently begun to understand in any detail. This book aims not only to document recent research on this important area of geology but also to explain current methods of investigation and the interpretation of results. The main aspects of petrology of high-grade, regional metamorphic rocks are covered as well as melting and fluid transport within the Earth's crust. Chapters on theoretical framework and relevant experiments are complemented by others on key regions illustrating high-grade metamorphism. These include Sri Lanka and central Australia, which are now being studied intensively for the first time, and the classic ground of the Adirondack Mountains in New York and the Lewisian of Scotland. The study of these areas is based largely on petrological lines but tectonic settings are also considered. As a guide to recent developments, the book is considered essential reading for research workers and students of geology and should provide an invaluable reference work for lecturers and a useful introduction for non-specialist geologists.
