PETROLOGIC DATA

Rock Number: 1

Rock Type: amphibolite
Descriptors:
cataclastic
basaltic composition

Field Description:

-tectonically brecciated, layered ampb.
-as the typical nubbly weathered surface and diamond shaped brecciated fragments in a carbonate matrix, typical of the basalts
-rock has a high density, greenish-black amphibole mixture that may have been derived from camatitic?? basalt
-the flat lying 335 fabric is the dominate structural fabric responsable form most of the shearing
