Witryna7 lip 2024 · How does heat affect metamorphism? Temperature changes affect the chemical equilibrium or cation balance in minerals. … Heat-driven metamorphism begins at temperatures as cold as 200˚C and can continue to occur at temperatures as high as 700°C-1,100°C . Higher temperatures would create magma, and thus, would … Witrynametamorphism, mineralogical and structural adjustments of solid rocks to physical and chemical conditions differing from those under which the rocks originally formed. Changes produced by surface conditions such as compaction are usually excluded. The most important agents of metamorphism include temperature, pressure, and fluids. …
