exsolved or
devitrified minerals form
lines and
shapes which are

alkali feldspar (near K-feldspar, KAlSi3O8, in composition)
includes exsolved lamellae or

Perthite is
either microcline or
orthoclase with thin
lamellae of
exsolved albite.
Amazon stone, or amazonite, is a
green variety of microcline. It...

cooling off it p****es a
phase boundary where kamacite is
exsolved from taenite.

partial melting occurs in
metamorphic paleosome.
Components exsolved by
partial melting are
called neosome (meaning ‘new body’),
