STRUCTURAL DATA

Planar Structures:
Structure type Strike Dip Separation
cataclastic foliation 21 48

PETROLOGIC DATA

Rock Number: 1

Rock Type: multi-component schlieric gneiss

Field Description:

-dominantly pink to beige weathering, med. grained homogeneous, equigranular, leucocratic (CI=1) GRDR
-essentially CWB camp-style material

-there are numerous schlieren and nebulitic inclusions of mafic seds or ampb.
