Frontiers in Geofluids

Frontiers in Geofluids is a collection of invited papers chosen to highlight recent developments in our understanding of geological fluids in different parts of the Earth, and published to mark the first ten years of publication of the journal Geofluids. The scope of the volume ranges from the fundamental properties of fluids and the phase relationships of fluids encountered in nature, to case studies of the role of fluids in natural processes. New developments in analytical and theoretical approaches to understanding fluid compositions, fluid properties, and geological fluid dynamics across a wide range of environments are included. A recurrent theme of research published in Geofluids is the way in which similar approaches can be applied to geological fluids in very different settings and this is reflected in the diverse range of applications of fluid studies that are included here. They include deep groundwater flow, hydrocarbons in faulted sedimentary basins, hydrothermal ores, and multiphase flow in mid-ocean ridge systems. Other topics covered are geothermal waters, crustal metamorphism, and fluids in magmatic systems.

The book will be of great interest to researchers and students interested in crustal and mantle fluids of all sorts.

Bruce Yardley is Professor in the School of Earth and Environment at the University of Leeds, UK, and was a founding editor of the journal Geofluids. His research concerns the nature and role of fluids in the crust, including metamorphic processes, hydrothermal ore systems and sedimentary basins. He obtained his PhD at the University of Bristol in 1975, and has been at the University of Leeds since 1985. He held a Harkness Fellowship at the University of Washington, Seattle, and has recently been a Humboldt Awardee at the Deutsches GeoForschungZentrum, Potsdam.

Craig Manning is a Professor of Geology and Geochemistry in the Department of Earth and Space Sciences at the University of California Los Angeles. He received BA degrees in Geology and in Geography from the University of Vermont, and MS and PhD degrees in Geology from Stanford University. His research focuses on experimental and theoretical study of geologic fluids at high pressure and temperature.

Grant Garven is a Professor in the Department of Geology and in the Department of Civil & Environmental Engineering at Tufts University, near Boston. Originally trained as a field geologist in the Canadian Shield, his career has mostly focused on mega-scale groundwater flow in sedimentary basins and related geologic processes. He received his BSc in Geology at the University of Regina, MS in Hydrology at the University of Arizona, and PhD degree at the University of British Columbia.
