Typical Minerals
QUARTZ > 20%
PLAGIOCLASE is greater than
Orthoclase (may be absent all together)
Mafics - < 10%
Detail Description
     In this greater detail we see the mixed clear to translucent light colored sodium plagioclase and quartz (still hard to separate in a photograph but appearing gray, clear, glassy, instead of white.) Orthoclase is notably absent.
     The mafic (black) minerals are still not easily identified even under this magnification. We need to be able to rotate the specimen under a microscope looking for the cleavages to be sure of identification, but they are mostly amphibole.
