Representative compositions for paragonite are given in Table 34. Paragonite
has a similar minor and trace element chemistry to muscovite, but is much more
restricted in its compositional variation from the ideal composition. Calcium is the

Rock-forming Minerals: Sheet silicates: clay minerals. Volume 3C
There is, however, some evidence of possible differences if comparisons
between muscovite and paragonite are indicative of the relative behaviour of illite
and brammalite. As indicated above, Barshad (1950) compared the ability of
muscovite ...

The Boundaries of the West African Craton
Albite displays numerous minute inclusions of quartz, white mica, euhedral bluish
acicular calcic amphi- bole, garnet, carbonate, rutile and paragonite, and
therefore does not represent a late phase. Mica-rich samples (c. 30 vol%) contain

Silicate Structures and dispersion system
Intergrowths of structurally related minerals, chiefly of micas such as muscovite
and paragonite (Na-muscovite) and of unmixing structures, are sometimes near
the limits of optical resolution in the dimensions of the single constituents, even ...

Ultrahigh Pressure Metamorphism
Most P-T shifts are difficult to predict quantitatively (see Guiraud et al., 1990),
because, among others, such elements, in particular Ca, can be introduced in
various NFMASH minerals, like garnet, glaucophane, jadeite and paragonite. A
simple ...
