Apr 23, 2023 · 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.

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 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.

Sericitic alteration or sericitization is a process of mineral alteration caused by hydrothermal fluids invading permeable country rock. Plagioclase feldspar within the rock is converted to sericite (sericite is not a mineral; it is a term that is used to describe any fine-grained white phyllosilicate when a distinction cannot be determined ...

May 9, 2023 · Hydrothermal alteration is a geological process that occurs when hot, mineral-rich fluids interact with rocks and minerals, changing their physical and chemical properties.

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 also occurs as the fine mica that gives the sheen to phyllite and schistose metamorphic rocks.

Sericite schist mineral data, information about Sericite schist, its properties and worldwide locations.

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.

A fine-grained form form of mica, usually Muscovite, that is somewhat silky in appearance. © Copyright 1997 - 2025 Hershel Friedman and Minerals.net, all rights reserved.

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.
