Large Igneous Provinces. Richard E. Ernst. Pp. 653. Cambridge University Press. 2014. ISBN 978-0-521-87177-8: Hardcover. Price $130. This book presents a comprehensive compilation of all aspects of large igneous provinces (LIPs). Published in 2014, the book is now the definitive source of information on the petrogenesis of this type of globally important, voluminous magmatic activity. In the first few pages, LIPs are characterized as magmatic provinces with areal extents >0.1 Mkm2 that are dominated by mafic magmas emplaced or erupted in intraplate settings during relatively short (1–5 m.y.) time intervals. Given these parameters, particularly areal extent, LIPs clearly represent significant contributions to global geologic evolution through time. This point is underscored, also in the introductory chapter, by a series of figures that aptly characterize the global time-space distribution of LIPs; an accompanying, particularly useful table identifies individual LIPs, quantifies their basic characteristics, and enumerates pertinent references. Accordingly, this compilation is a welcome addition to the geologic literature. As portrayed in this volume, the number and extent of LIPs globally require that processes responsible for the associated magmatism be documented and placed in a modern petrogenetic context to enhance our understanding of the geospatial and temporal aspects of global geologic evolution. The book includes many well-prepared black-and-white illustrations that document essential aspects of LIPs, including geologic setting, important petrogenetic processes, and geochemical relations. Ernst, who has spent a career studying LIPs, is well qualified to have assembled the basic observational data and interpretations contained in this book because of his profound, …
