Geothermal metamorphism
WebIntroduction. Metamorphic rocks record evidence of change in pressure (P) and temperature (T) with time (t), commonly expressed as a P–T–t path, which represents the record of heating and cooling during burial and exhumation derived from mineral assemblages and compositions combined with geochronology (e.g. Brown, Reference Brown 1993, … Webtions that constrain geothermal gradients in continental arcs. We then describe a conceptual framework for using wall-rock ther-mobarometry to constrain the background geothermal gradient in continental magmatic arcs.
