Muscovite - Geology is the Way
Muscovite is a dioctahedral sheet silicate or phyllosilicate. Its structure consists of a pile of ‘sheets’ of (Si,Al)O 4 tetrahedrons interconnected as six-sided rings extending infinitely in the 2D plane, and dioctahedral ‘gibbsite’ layers, where each anion (O 2- …

Muscovite is a common rock-forming silicate mineral within the mica group. The approximate chemical formula of muscovite is KAl2(Si3Al)O10(OH,F)2 [27]. It is generally found as white or...

Natural muscovite mica layer is structured in a series of three sheets (Figure 1 a): an octahedral sheet of alumina (AlOOH) sandwiched between two identical tetrahedral sheets of silica.

Muscovite, KAl 2 (AlSi 3)O 10 (OH,F) 2, has a monoclinic crystal system with a tabular habit. The octahedral layer is occupied by Al 3+ and the mineral is therefore dioctahedral, since two-thirds of the octahedra are occupied. The source of the lattice charge is the presence of Al 3+ in place of Si 4+ in 1/4 of the tetrahedral sites.

Muscovite - Wikipedia
Muscovite (also known as common mica, isinglass, or potash mica [6]) is a hydrated phyllosilicate mineral of aluminium and potassium with formula KAl 2 (AlSi 3 O 10)(F,OH) 2, or 2 (Al 2 O 3) 3 (SiO 2) 6 (H 2 O). It has a highly perfect basal cleavage yielding remarkably thin laminae (sheets) which are often highly elastic.

Muscovite is very common in large variety of metamorphic rocks including slate, schist, phyllite, gneiss, hornfels and quartzite. This picture of Muscovite shows the characteristic small cleavage lines as well as the differences between Muscovite and Biotite.

A diagram of muscovite structure reflecting the a axis projection. While muscovite has been the subject of several Raman studies ( Loh, 1973; Harley et al., 1982; Tlili et al., 1989; McKeown et al., 1999 ), investigation of Al-rich micas has been dominated by other spectroscopic techniques such as Mössbauer, optical absorption, infrared (IR ...
Muscovite Mineral | Uses and Properties - Geology.com
Muscovite is the most common mineral of the mica family. It is an important rock-forming mineral present in igneous, metamorphic, and sedimentary rocks. Like other micas it readily cleaves into thin transparent sheets. Muscovite sheets have a pearly to vitreous luster on their surface.
