Book Review Timescales of Magmatic Processes: from Core to Atmosphere, Eds. A. Dosseto, S. P. Turner and J. A. Van Ormans, Wiley-Blackwell, 2011; ISBN: 978-1-443-3260-5 (Cloth), ISBN: 978-1-4443-3261-2 (pbk) EWA SŁABY1 Typing the key-word ‘‘magmatism’’ while searching for books returns hundreds of results. There are many books in which authors consider various topics related to magmatism’s nature and origin, its connection to tectonics, metallogeny, mineralization, its regional development or its expansion during selected geological periods. Edited by Anthony Dosseto, Simon P. Turner and James A. Van Orman, the book ‘‘Timescales of magmatic processes’’ concentrates on a particular topic which is crucial for understanding every magmatic process that ever took place anywhere—namely, the timing of the process. Choosing this particular aspect is a great, completely new idea, which has no counterpart in previously published books. Even though undoubtedly rapidly growing amounts of research and data makes the subject sufficiently mature to warrant an overview, the topic selection itself deserves special respect. This unique book will certainly be noticed and used by the broad scientific community. The book contains extensive Introduction, written by the editors. Antony Dosseto and Simon P. Turner are reputable experts on isotope and thermal constraints, and James A. Van Orman is an expert on diffusion constraints on the rate of magma generation and ascent. The Introduction is followed by 11 chapters, co-authored by 20 outstanding professionals from 15 scientific institutions recognized worldwide. Chapter 1 addresses early differentiation of the Earth and Moon. G. Caro and T. Kleine introduce

Hf-182W and 146Sm-142Nd, which are crucial for chronological constraints on major episodes, like core extraction, its re-equilibration with a magma ocean, mantle and crust differentiation, etc. Determination of the timing of all those processes requires precise knowledge and understanding of all of them. Authors present areas where present knowledge can give a more definitive evaluation of the timescale, and those where our incomplete knowledge makes the estimation less precise. A genetical relation of the Earth and Moon is obvious, as the latter is a product of a giant collision of an embryonic protoplanet with the protoEarth, so the timescale of Earth accretion and segregation is shown in relation to Moon. The next two chapters concentrate on the timescale of melt production. The problem is examined with use of two tools. The authors of chapter 2, J. A. Van Orman and A. E. Saal, explain the control of the diffusion of trace element fractionation (with special emphasis on the U-series) as a tool to extract information on the melting rate in the mantle. They show a set of models, from simple ones to the more developed and more realistic. Some of them, applying diffusive fr
