Sericite is the name given to very fine, ragged grains and aggregates of white (colourless) micas, typically made of muscovite, illite, or paragonite. [1] Sericite is produced by the alteration of orthoclase or plagioclase feldspars in areas that have been subjected to hydrothermal alteration (also see Sericitic alteration ) typically ...

Named in 1852 by Karl/Carl List from the Greek seirος meaning "silken". A variety of Muscovite A term for a fine-grained white, pale green to oily greenish mica, mainly Muscovite (rarely Paragonite). Neoproterozoic to Quaternary : 670 Ma to 1.3 ± 0.1 Ma - based on 27 recorded ages. A chromium-bearing variety of sericite. See also fuchsite.

2023年4月23日 · Sericite is a type of mineral that belongs to the mica group. It is a fine-grained, muscovite mica with a silky luster and is typically white, gray, or pale yellow in color. Sericite is found in a wide range of rock types, including metamorphic, igneous, and sedimentary rocks.

These specimens are replacements of silvery-golden muscovite mica (variety "sericite") after trapiche habit cordierite-indialite. The form creates a very beautiful pattern, not unlike ... © Brian Kosnar - Mineral Classics. Muscovite (Var: Sericite) King County, Washington, USA.

Sericite, fine-grained variety of either of the silicate minerals muscovite and paragonite

Sericite is a common alteration mineral of orthoclase or plagioclase feldspars in areas that have been subjected to hydrothermal alteration typically associated with copper, tin, or other hydrothermal ore deposits.

Sericite, the fine-grained form of muscovite or ‘white mica’, occurs as a result of hydrothermal alteration processes in rocks throughout the Cheviot Hills. It is commonly seen in altered feldspar crystals, particularly plagioclase, associated with secondary minerals that give host crystals a cloudy appearance.

Sericite is the name given to very fine, ragged grains and aggregates of white (colourless) micas, typically made of muscovite, illite, or paragonite. Sericite ...

Sericite is a clay mineral that is abundant on alarge scale in nature. Its abundance and low cost mean that sericite is can be utilized as an effective raw material for the production of various industrial products.

Sericite is name given to very fine, ragged grains and aggregates of white mica – usually muscovite – produced by the alteration of feldspars or other minerals. Included grains of zircon or other radioactive minerals may form pale pleochroic halos in surrounding muscovite.
