WebMetamorphic Rocks. Metamorphic rocks are any rock type that has been altered by heat, pressure, and/or the chemical action of fluids and gases. Metamorphic rocks are classified by their structure and their dominant minerals. Metamorphic rock structure is either foliated (has a definite planar structure) or nonfoliated (massive, without structure). WebMay 12, 2024 · Scientists have determined two different types of metamorphic rocks - foliated and non-foliated rocks. Foliation describes a metamorphic rock whose minerals are aligned in layers. These...

How are Foliated Rocks Formed? - Study.com
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, … See more Slate is a fine-grained metamorphic rock that shows no obvious compositional layering, but can easily be split into thin slabs and plates. It is usually formed by low-grade regional metamorphism of mudrock. … See more Europe Most slate in Europe today comes from Spain, the world's largest producer and exporter of natural … See more • Page, William (ed.)
