How are metamorphic rocks classified?
How are metamorphic rocks classified? Metamorphic rocks are broadly classified as foliated or non-foliated. Non-foliated metamorphic rocks do not have aligned mineral crystals. Non-foliated rocks form when pressure is uniform, or near the surface where pressure is very low. The other minerals have been crushed and deformed into a fine-grained matrix (Mtx). What are metamorphic […]
