PETROLOGIC DATA

Rock Number: 1

Rock Type: tonalite
Descriptors:
augened
biotite
Field Description:

-less obvious now whether these augen are sheared pegs. or porphyroblasts---now I think it may be a combination of both

-slightly schlieric

Rock Number: 2

Rock Type: amphibolite
Field Description:

-waxey grey BO amphibole
-heavily assimilated--may have had HB
