  • Muscovite | mineral | Britannica

    Muscovite, also called common mica, potash mica, or isinglass, abundant silicate mineral that contains potassium and aluminum. Muscovite is the most common member of the mica group. Because of its perfect cleavage, it can occur in thin, transparent, but durable sheets.Sheets of muscovite were used in Russia for windowpanes and became known as Muscovy glass (isinglass), hence its common name.

    Jan 01, 2017· The 40 Ar/ 39 Ar cooling ages (263-259 Ma) yielded from muscovite suggest the amphibolite facies metamorphism (>263 Ma) occurred at oceanic subduction stage. The distinctly staged metamorphism defines a clockwise and warming decompression P-T-t path which reveals an underplating process following the early subduction erosion.

    As the peak metamorphic temperature significantly higher than the 40 Ar/ 39 Ar closure temperature of muscovite [∼400°C, Harrison et al., 2009], the muscovite 40 Ar/ 39 Ar ages (263–259 Ma) should reflect the timing when the rocks had cooled from 470 to 520°C at peak metamorphic stage down to ∼400°C during the late exhumation process.

    Muscovite Muscovite is a member of the mica group of silicate minerals (sheet silicates) in which the base of all of the SiO 4 tetrahedra lie in one plane and three corners of the base are shared with the neighbouring tetrahedra. This creates a strongly layered sheet-like structure, hence the term sheet silicate (the sheets are weakly bound together by layers of potassium ions).
