STRUCTURAL DATA

Planar Structures:
Structure type Strike Dip Separation
gneissosity 72 66

PETROLOGIC DATA

Rock Number: 1

Rock Type: granodiorite
Descriptors:
augened
biotite - hornblende bearing

Field Description:

-raft complex with numerous large inclusions of dominantly sedimentary amphibolite and volcanic wacke
-many inclusions are due to disruption of schollen
-layering in inclusions are generally at a high angly to gneissosity
-there are several small inclusions of hornblendite and leuco-gabbro-probably derived from unit 5
