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 ...

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 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.

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

Sericitic alteration or sericitization is a process of mineral alteration caused by hydrothermal fluids invading permeable country rock.

Nov 13, 2015 · As its name implies, this type of schist also contains significant amounts of sericite, which is a fine-grained type of either muscovite or paragonite, both of which are relatively abundant silicate minerals.
