WebApr 16, 2014 · Metamorphic Processes • Recrystallization: The most common process in the formation of metamorphic rocks is recrystallization. In this process the grains making up the protolith change shape and size. The identity of the mineral does not change during this process, only the texture. Recrystallization occurs due to heating of the protolith. WebNov 30, 2024 · Equally important are the changes in the chemical environment that result in two metamorphic processes: (1) mechanical dislocation where the rock is deformed, particularly as a result of differential stress; and (2) chemical recrystallization where the mineral assemblage becomes out of balance due to changes in temperature and …
