Muscovite – Geology is the Way
Muscovite is the most common white mica in igneous and metamorphic rocks and also occurs in sedimentary rocks as a detrital mineral. The name derives from the Elizabethan term 'Muscovy-glass', since in medieval Russia muscovite (which breaks in transparent sheets) was used as an alternative to glass in windows.

Muscovite
Muscovite. Briefly, muscovite (also known as common mica, isinglass, or potash mica) is a hydrated phyllosilicate mineral of aluminum and potassium [KAl2 (AlSi3O10 (FOH)2], or (KF)2 (Al2O3) (SiO2)6 (H2O)] which has a highly perfect basal cleabage that yields thin laminae (sheets) which are often highly elastic.

Possible origin of life between mica sheets: does life imitate mica?
A muscovite mica world provides an environment high in K +. Muscovite mica's anionic sheets are bridged by K +, which hold the anionic mica sheets together, with one K + per 0.5 nm on the hexagonal lattices of pairs of mica sheets (Pauling, 1930). The origin of this K + has not been explained by other hypotheses about the origin of life.

Dielectric breakdown of 2D muscovite mica
We find charge injection occurs prior to BD for both muscovite mica and synthetic mica (Supplementary Fig. S5). In contrast, whilst Davidson and Yoffe also find current flow prior to BD for natural micas 22, 23, they observe no measurable current for synthetic mica. We attribute this difference to the much thinner films used in our work.
Mica
Mica. Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.

Of the 28 known species of the mica group, only 6 are common rock-forming minerals. 1) Muscovite, (Potassium Mica) the common light-colored mica. It was originally called "Muscovy glass" because it came from the Muscovy province of Russia. 2) Biotite, (Magnesium Iron Mica) which is typically black or nearly so, is the most abundant.
