Definition
A metamorphic reaction is a chemical reaction that produces, or changes, an assemblage of metamorphic mineral and fluid phases in a rock. The changes affect the compositions of the phases and may also include changes in the phases that are present. Metamorphic processes are those processes that drive metamorphic reactions, by causing a change in the chemical conditions of the rock, such as the pressure or temperature. Metamorphic processes also commonly drive deformation .
Introduction
A metamorphic rock is a rock that has undergone mineralogical changes due to changing thermodynamic conditions since its formation. Prior to any metamorphism, the original rock, or protolith, may have been formed by solidification of a melt (an igneous protolith) or the lithification of discrete grains derived from weathering (a sedimentary protolith). Mineralogical changes are driven by metamorphic processes, which give rise to a great diversity of metamorphic minerals and mineral...
