Geological Society

2018-6-12 · Metamorphic changes do not involve melting (higher temperatures are needed for that), nor any change to the chemical composition of the rock. However, mineral grains (like quartz and clay) react chemically with each other to form new minerals (like mica and garnet) and new rock textures.
