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 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. …

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 …

Apr 13, 2019 · 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 is known for several significant and nuanced characteristics, particularly its color variations, texture, and luster. Each of these features not only distinguishes phyllite from other …

Phyllite is a foliated metamorphic rock rich in tiny sheets of sericite mica. Phyllite is a durable and soft rock and used as decorative aggregates, floor tiles, and as exterior building, or facing stone.

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 …

Phyllite is metamorphosed shale. It is a foliated metamorphic rock, often with a silky sheen due to the presence of tiny mica crystals. The cleavage surface of phyllite is not flat like slate, but is …

Phyllites, which form at higher metamorphic grades than slates, sparkle because clay minerals have metamorphosed to produce small grains of reflective mica.
