'The book Principles of Metamorphic Petrology is an absolutely wonderful work and a delight to read. I found the book very refreshing content-wise [with] clarity in terms of the writing style. … Useful glossary, a voluminous bibliography (from Abbott to Zwart) running to almost 70 pages and an index … This book will be of interest to both … metamorphic petrologists and geochronologists.' Journal of the Geological Society of India '… a good book and is recommended as an advanced textbook of metamorphic petrology …' Mineralogical Magazine 'This is a book to read and a book to keep as a reference. It is a must-have for every student of tectonics.' EOS, Transactions, American Geophysical Union
