Foliated non foliated metamorphic
WebMetamorphic rocks are broadly classified as foliated or non-foliated. Non-foliated metamorphic rocks do not have aligned mineral crystals. Non-foliated rocks form when … WebThe majority of a non-foliated metamorphic rock contains mostly one mineral. Nonetheless, metamorphism has still taken place within these rocks; the mineral grains have recrystallized , interlocked, and grown larger. As a consequence, non-foliated rocks are much more durable and resistant to weathering than their parent rocks.
