Sample 02MW0200 is a granodiorite with the
assemblage plagioclase (60%), quartz (18%), K-feldspar (15%), biotite
(5%), chlorite (1%), oxides (1%), and trace epidote and
sericite/muscovite. Plagioclase grains show albite and pericline
twinning and occur as porphyries and matrix grains. Some plagioclase
grains are intergrown with K-feldspar. A weak, wavy foliation is defined
by micas that wrap feldspar porphyries.
