WebNonfoliated metamorphic rocks lack foliated texture because they often lack platy minerals such as micas. They commonly result from contact or regional metamorphism. Examples include marble, quartzite, greenstone, hornfel, and anthracite. Marble Marble is low- to high-grade metamorphosed limestone or dolostone (both of which are carbonate rocks). WebSlates are generally fine‐grained, dark‐colored, metamorphosed sedimentary rocks that split easily along slaty foliations and were formed under low‐grade temperature and pressure conditions. Phyllites are slightly more metamorphosed than slates and contain mica crystals that impart a glossy sheen.

What are Igneous, Sedimentary, & Metamorphic Rocks? - Utah

Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. WebPhyllite is intermediate between slate and schist. It differs from slate in that crystallization of micaeous minerals imparts a sheen to the rock; it differs from schist in that grains are too small for megascopic identification.
