2. Phyllite - Wikipedia

   en.wikipedia.org/wiki/Phyllite

   Phyllite Photomicrograph of thin section of phyllite (in cross polarised light) Fractured Duke stone showing phyllitic texture Phyllite. Phyllite (/ ˈ f ɪ l aɪ t / FIL-yte) is a type of foliated metamorphic rock formed from slate that is further metamorphosed so that very fine grained white mica achieves a preferred orientation. [1]

3. Foliation (geology) - Wikipedia

   en.wikipedia.org/wiki/Foliation_(geology)

   More technically, foliation is any penetrative planar fabric present in metamorphic rocks. Rocks exhibiting foliation include the standard sequence formed by the prograde metamorphism of mudrocks; slate, phyllite, schist and gneiss. The slatey cleavage typical of slate is due to the preferred orientation of microscopic phyllosilicate crystals ...

4. Argillite - Wikipedia

   en.wikipedia.org/wiki/Argillite

   [citation needed] These rocks, although variable in composition, are typically high in aluminium and silica with variable alkali and alkaline earth cations. The term pelitic or pelite is often applied to these sediments and rocks. Metamorphism of argillites produces slate, phyllite, and pelitic schist.

5. Schist - Wikipedia

   en.wikipedia.org/wiki/Schist

   The composition of the rock must permit formation of abundant platy minerals. For example, the clay minerals in mudstone are metamorphosed to mica, producing a mica schist. [18] Early stages of metamorphism convert mudstone to a very fine-grained metamorphic rock called slate, which with further metamorphism becomes fine-grained phyllite ...

6. Slate - Wikipedia

   en.wikipedia.org/wiki/Slate

   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. [ 1 ]

9. Lithology - Wikipedia

   en.wikipedia.org/wiki/Lithology

   Carbonate rocks are classified with the Dunham or Folk classification schemes according to the constituents of the carbonate rock. [13] Metamorphic rock naming can be based on protolith, mineral composition, texture, or metamorphic facies. Naming based on texture and a pelite (e.g., shale, mudrock) protolith can be used to define slate and ...
