Fluid flow is fundamental to many geological processes, including the development of natural resources of hydrocarbons, ore deposits and water. Modelling of these processes requires information on the timing of fluid flow events and the interaction of fluids with surrounding rocks. In addition to isotopic methods, a diversity of approaches has been developed to assess the timing of events, including palaeomagnetism, fission track analysis and fluid inclusion studies. Many techniques also provide information on the duration of fluid flow events. The papers in this volume represent the range of approaches to determine the dating and duration of fluid flow events and fluid-rock interaction. The first overview of methods of dating fluid flow; examples of commercial application of dating methods; explanations of methodology; suitable for advanced teaching and with extensive bibliographies. Readership: This volume will be of interest to geologists in the hydrocarbon and minerals industries and in academia, and to geochemists and hydrogeologists.
