Granites are emblematic rocks developed from a magma that crystallized in the Earth's crust. They ultimately outcrop at the surface of every continent. This book offers a modern presentation of granitic rocks. It considers granites in their geological spatial and temporal frame, and in relation to plate tectonics and Earth history. The book - translated, edited, and updated from the original French edition Pétrologie des Granites published by Vuibert in 2011 - gives a modern presentation of granitic rocks, or granites, from magma genesis to their emplacement into the crust and their crystallization. Mineralogical, petrological, physical, and economical aspects are explored and developed in a succession. The text is supported throughout by a large number of illustrations, descriptions of modern techniques, and additional boxes holding further discussions for those wishing to deepen their knowledge of the subject.
Autorentext
Anne Nédélec and Jean-Luc Bouchez are Professors in Earth Sciences at the University of Toulouse. Both are based at the Observatoire Midi-Pyrénées (Géosciences Environnement Toulouse). Anne is a petrologist, specialist of Precambrian Geology. Jean-Luc, a specialist in rock deformation, participated in the development of structural studies in magmatic rocks. Both have a broad experience in laboratory and field studies in Africa, Madagascar, Brazil, Iran, and France, among others. Peter Bowden has been Professeur Invité in the Département de Géologie at Université de Saint Etienne since 1998. He was Editor-in-Chief of the Journal of African Earth Sciences from 1993 to 2001, and Senior Lecturer and co-ordinator for the BSc Geochemistry degree at the University of St Andrews, Scotland, from 1987 to 1998. He is a specialist in African Geology and an expert on A-type granites. =
