<p>“The reader will return repeatedly to the excellent sketches and tables throughout the book, and the "how to” sections provide some memorable highlights.” (<i>PESGB</i>, 1 January 2014)</p> <p>“A second edition of The Field Description of Igneous Rocks has been long overdue, and the authors are to be commended for reproducing an excellent and comprehensively revised version.” (<i>Geological Journal</i>, 1 January 2013) </p> <p>“Overall, if you are examining igneous rocks in the field or studying an OU course then, yes, I would recommend this book.” (<i>Open University Geological Society Journal</i>, 1 November 2012)</p> <p>“To be fair, the authors of this book have undertaken an incredibly difficult task. They succeed at reaching the novice audience but fall a bit short when it comes to more experienced mapping geologists.” (<i>Environmental & Engineering Geoscience</i>, 1 November 2012)</p> "This book is certain to be of use to all geological students and enthusiasts interested in studying igneous geology in the field." (American Mineralogist, 2012) <p>"As a pocket field guide, the book, because of its size, sometimes undersells the fantastic images it contains, but as a whole, it is a welcome, useful resource. Highly recommended. Upper-division undergraduates." (Choice, 1 October 2011)</p>
