PETROLOGIC DATA

Rock Number: 1

Rock Type: granodiorite
Descriptors:
schistose
biotite
Field Description:

-homo equi. grey GRDR
-contains numerous inclusions of ampb.
-not really recognizable as a unit encountered before unless it is a less sheared example of the cata GRDR (rock 2 6284)

Rock Number: 2

Rock Type: amphibolite
Field Description:

-various ampb inclusions-most are just fine grained black cracks and were probably basalts, but one large inclusion (sample) was probably a med. grained HB gabbro
-extensivly intruded by rock 2 and then folded and sheared

Rock Number: 3

Rock Type: granodiorite
Descriptors:
augened
leucocratic
Field Description:

-many 5 to 20 cm dikes parallel to foliation of the younger GR bearing white GRDR

Minerals of Note
Mineral | Abundance (%)
garnet
magnetite

Rock Number: 4

Rock Type: granite
Descriptors:
cataclastic
aplitic
Field Description:

-thin dikes of highly sheared aplite-movement of shear planes seems to be preferential to zones invaded by aplitic as they are more sheared than the bulk of the outcrop
