Sample 95MW0212 is a syenitic protomylonite
containing K-feldspar (70%), plagioclase (25%), unidentifiable fine
matrix material (4%), oxides (1%), and trace epidote. K-feldspar is up
to 40% perthitic and tartan twinned, occurring in the matrix and as
porphyries. Plagioclase shows albite twinning and subgrains in
non-recrystallized clasts. Matrix material is ultra fine-grained and
shows a high birefringence. It is probably a "mesh" of felsic minerals.
Oxides occur as rounded, bulbous grains, in proximity to epidote.
