Quantifying the timescales of current geological processes iscritical for constraining the physical mechanisms operating on theEarth today. Since the Earth's origin 4.55 billion years agomagmatic processes have continued to shape the Earth, producing themajor reservoirs that exist today (core, mantle, crust, oceans andatmosphere) and promoting their continued evolution. But keyquestions remain. When did the core form and how quickly? How aremagmas produced in the mantle, and how rapidly do they traveltowards the surface? How long do magmas reside in the crust,differentiating and interacting with the host rocks to yield thediverse set of igneous rocks we see today? How fast are volcanicgases such as carbon dioxide released into the atmosphere?
This book addresses these and other questions by reviewing thelatest advances in a wide range of Earth Science disciplines: fromthe measurement of short-lived radionuclides to the study ofelement diffusion in crystals and numerical modelling of magmabehaviour. It will be invaluable reading for advanced undergraduateand graduate students, as well as igneous petrologists,mineralogists and geochemists involved in the study of igneousrocks and processes.

Anthony Dosseto did his PhD at the Institut de Physique duGlobe de Paris in France before taking up a postdoctoral positionat Macquarie University in Sydney, Australia in 2004. In 2009, hemoved to the Univesity of Wollongong, Australia and in 2010 wasawarded an Australian Research Council Future Fellowship.
Simon P. Turner obtained his PhD at the University ofAdelaide in 1991. Currently he holds an ARC Professorial Fellowshipin the Department of Earth and Planetary Sciences at MacquarieUniversity, Sydney, Australia where he specializes in theapplication of U-series isotopes to constraining the time scales ofEarth processes with particular emphasis on subduction zonemagmatism.
James A. Van Orman is an Associate Professor inGeological Sciences at Case Western Reserve University. Hewas awarded a PhD in geochemistry at MIT and undertook postdoctoralresearch in mineral physics and geochemistry at the CarnegieInstitution of Washington. His research is centered ondiffusion in minerals and melts, with current interests in deepplanetary rheology, chemical exchange processes, andgeochronology.
