Biotite
Mica minerals have perfect basal cleavage which makes it easy to separate them into many thin folia. Biotite (on the left) and muscovite are the most widespread micas. Most biotite group minerals are black in color, although the color gets lighter (brownish) if the sheet is thin enough for the light to penetrate it. Mgrich phlogopite is brown or greenish. The density is highly variable: ...

facts on mica the mineral
The mica mineral group includes 34 phyllosilie minerals, all with a layered, platy texture. The mineral has been known for millennia: Mica was first mined in India about 4,000 years ago, where it was used primarily in medicines.

LithiumMica Minerals Case Study
The mica group of minerals are phyllosilies with a common basic crystal structure. Of the 41 species currently known, we are going to demonstrate the ability of Xray diffraction (XRD) to distinguish 4 of them: muscovite, biotite, zinnwaldite and lepidolite. Muscovite and biotite are two of the more important rockforming micas (well known to geologists), but few workers have experience of ...

Micas and Other Phyllosilies
Mica group minerals are grouped according to their interlayer ions. The interlayer (I) composition will determine if the micas are classified as brittle, ordinary or true, and interlayer deficient. These groups are further broken down by the octahedral layer's composition. The structural formula unit of mica includes room for three octahedrally coordinated vacancies in the M layer to be ...
