Descriptors:
cataclastic
hornblende bearing
Field Description:

-grey weathering homo-equi mafic sediment
-strong shear fabric has reduced it to a leucoampb.
-augen of more leucocratic material may have been more felsic layers that were disrupted and transposed into the shear plane

Descriptors:
cataclastic
leucocratic
Field Description:

-pink weathering with fresh surface med. grey
-quartz 30 to 35% as elongate stringers
-highly cataclastic
