An overview of diverse responses to diverse processes at high crustal temperatures

Part of the The Mineralogical Society Series book series (MIBS, volume 2)


At the highest temperatures of regional metamorphism, crustal rocks undergo combinations of deformation, mineral reactions, partial melting, and geochemical transport processes. The scientific challenge goes beyond simple description of these processes, to the estimation of physical conditions (notably pressure, P and temperature, T), eventually leading to inferences about the tectonic régimes and heat sources responsible for the pressure-temperature-time (P-T-t) evolution of a region (from cold to hot followed by cooling and uplift to its present position at the Earth’s surface). This volume comprises reviews which explain the current state of progress towards these goals using different methods and in several different high-grade terranes.
