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.
