Book review: Layered Intrusions. Edited by Bernard Charlier, Olivier Namur, Rais Latypov, Christian Tegner (2015) Springer, 748 p. $179 (Hardcover), $139 (eBook), ISBN 978-94-017-9651-4. The book entitled Layered Intrusions is a well-sized collection of 15 chapters written by 36 authors—each being an expert in their prevailing sub-discipline. Hence, the book covers all aspects of the emplacement and evolution of large mafic to ultramafic magma chambers. All chapters provide a broad introduction to their topics and are richly illustrated. References appear at the end of each chapter and support the readers’ further education on particular topics. The book is well written and intends to aid in further training of graduate and undergraduate students; however, the addition of access to illustrations and figures online would increase its value as a teaching resource. All chapters are available as e-books, so with a little extra effort and expense, if you have the hard cover version, images and figures for teaching can be obtained from these. Each of the 15 chapters are available separately for $29.95. Photographs and photomicrographs are mostly color images, where grayscale images are used, these are labelled to avoid any confusion that might arise. The book is organized into two main parts that are summarized in the two paragraphs below: the first part includes reviews and new views on the formation processes of layered intrusions. The second part reviews the state of recent cutting-edge research of layered intrusions in the field. The book begins with the geochronology of layered intrusions. Chapter 1 provides information about advantages and disadvantages of well-known dating methods, e.g., U-Th-Pb, K-Ar and which of these best applied to layered intrusions from different periods in the Earth’s history. Cooling rates of the intrusions are determined by choosing various mineral species with different closing temperatures, the temperature at which radiogenic elements are retained in the crystal lattice. The case studies suggest that duration of magmatism of layered intrusions can be restricted to brief …
