Summary

This unique book is one of the first to address the timescales of magmatic processes over the entire spectrum of geological reservoirs: from core to atmosphere. Moreover, previous publications have generally constituted catalogs of geochemical techniques that can be used to constrain the timescales of magmatic processes or have focused on a single geochemical technique. The focus of this book is on the geological processes rather than the tools to study them and integrates techniques from geochemistry as well as from geophysics.

Author Biography

Anthony Dosseto did his PhD at the Institut de Physique du Globe de Paris in France before taking up a postdoctoral position at Macquarie University in Sydney, Australia in 2004. In 2009, he moved to the Univesity of Wollongong, Australia and in 2010 was awarded an Australian Research Council Future Fellowship.

Simon P. Turner obtained his PhD at the University of Adelaide in 1991. Currently he holds an ARC Professorial Fellowship in the Department of Earth and Planetary Sciences at Macquarie University, Sydney, Australia where he specializes in the application of U-series isotopes to constraining the time scales of Earth processes with particular emphasis on subduction zone magmatism.

James A. Van Orman is an Associate Professor in Geological Sciences at Case Western Reserve University.  He was awarded a PhD in geochemistry at MIT and undertook postdoctoral research in mineral physics and geochemistry at the Carnegie Institution of Washington.  His research is centered on diffusion in minerals and melts, with current interests in deep planetary rheology, chemical exchange processes, and geochronology.
