Question

Quizplus · Accepted Answer

The two most common non-foliated metamorphic rocks are quartzite and marble. Quartzite is formed from sandstone, while marble is formed from limestone. Neither of these rocks have a layered or foliated appearance, unlike rocks such as slate, phyllite, and gneiss. Migmatite is a unique rock that has both igneous and metamorphic characteristics, and can have either foliated or non-foliated texture.
