- Phyllite - Wikipedia
Phyllite ( ˈfɪlaɪt 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]
- Phyllite: Metamorphic Rock - Pictures, Definition More
Phyllite is a foliated metamorphic rock that has been subjected to low levels of heat, pressure and chemical activity It is composed mainly of flake-shaped mica minerals in parallel alignment The strong parallel alignment of the mica grains allows the rock to be easily split into sheets or slabs
- Phyllite | Metamorphic, Foliated, Schist | Britannica
phyllite, fine-grained metamorphic rock formed by the reconstitution of fine-grained, parent sedimentary rocks, such as mudstones or shales Phyllite has a marked fissility (a tendency to split into sheets or slabs) due to the parallel alignment of platy minerals; it may have a sheen on its surfaces due to tiny plates of micas
- Phyllite | Composition, Properties, Formation, Uses » Geology Science
Phyllite is mainly composed of fine grains of mica minerals that are muscovite, or sericite Also fine grained feldspar and quartz are frequently major in phyllite
- Phyllite: Identification, Pictures Info for Rockhounds
Phyllite is a fine-grained foliated metamorphic rock primarily made of quartz, chlorite, and mica minerals like muscovite and sericite Known for its characteristic silky sheen, it often appears wavy or crinkled and tends to easily split into thin sheets
- Phyllite - Geology is the Way
A phyllite is a fine-grained, foliated metamorphic rock with a strong fissility Its primary feature is that foliation planes show a lustrous sheen, caused by the presence of oriented phyllosilicates (mostly white mica)
- Exploring Phyllite Rock: Formation, Properties, and Uses
Phyllite is a fine-grained metamorphic rock that typically exhibits a distinct sheen, making it visually appealing Its composition largely consists of quartz and mica minerals, mainly biotite and muscovite, which account for its lustrous surface
