`...one of the most important books about layered intrusions since Layered Igneous Rocks by Wagner and Brown.' Economic Geology, 83:2 (1988) `This book uniquely covers this range with an abundance of first-hand field observations and a good dose of process conceptualization, magma physics, and crystal growth kinetics. Three things set this book apart from most others in this vein: each paper is to the point, worth reading, and even worth studying; the abundant photographs are excellent, not only in choice but in reproduction, continually drawing one into the text; and a strong interawareness of field, experiment, and theory appears in nearly every paper. This book is a landmark publication, literally reeking of wonderful field observations and a host of well thought out and well presented ideas. Every serious igneous petrologist will want this book. It is simply excellent. Parsons has done a splendid job.' EOS, September 1988
