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
...

Blueschists and Eclogites
Introduction of Fe203 moved the omphaciteglaucophane-paragonite field
towards the high-pressure side, and the barroisite-omphacite-paragonite field
towards the high-temperature side. A critical assemblage in ortho- and
paragneisses is ...

assemblage: omphacite + garnet -* chloritoid + glaucophane + epidote the
chloritoid and glaucophane themselves later being replaced by paragonite +
chlorite.

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
...

High Quality Content by WIKIPEDIA articles! Paragonite, also known as Natron-Glimmer, is a mineral, related to muscovite. Its empirical formula is NaAl2.

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 ...

Phase Relations in the System Albite-Paragonite-Quartz-HjO In view of the
observation that albite dissolved incongruently, I first determined phase relations
among albite, paragonite, quartz, melt, and H2O. Results are given in table 2-1
and ...
