Coacervation of biopolymers on muscovite surface
With decreasing ss-oligo concentration from 6.0 to 1.5 mg/ml, the coacervation of Q-dextran and ss-oligo on the muscovite surface becomes stronger as demonstrated by the fluorescence intensity and the size of the coacervates . It is reasonable as the +/− charge ratio of the Q-dextran/ss-oligo coacervates increases from 0.25 to unity.

The geochemical differentiation of S-type pegmatites
Pegmatites often exhibit regional as well as internal zonation. In this study, we use major and trace element and Li–B isotopic composition of muscovite and tourmaline from internally zoned and un-zoned S-type pegmatites and their host granites to characterize the geochemical and isotopic fractionation associated with their formation. The internally zoned …

Included among these are V-rich muscovite and V-bearing phlogopite. Evaluation of the reported sample chemistries (with V 2 O 3 concentrations as high as 17.55%) show that their "V-rich muscovites" are in many cases roscoelite. The samples, however, are chemically zoned and occasionally tend towards a V-rich core.

Muscovite | Properties, Occurrence, Uses
Muscovite is a common mineral that belongs to the mica group. It is a silicate mineral that is characterized by its thin, sheet-like structure. Muscovite is composed of potassium (K), aluminum (Al), silicon (Si), and oxygen (O) atoms arranged in sheets, and it is known for its excellent cleavage, which allows it to be easily split into thin, flexible sheets.
