PETROLOGIC DATA

Rock Number: 1

Rock Type: amphibolite
Descriptors:
massive
basaltic composition
Field Description:

-salt and pepper textured--HB lineate ampb.
-appears to be same variation in colour and grain size suggesting a layered rock but this is not consistant
-major difference appears to be that some layers are massive while others have quartz - carbonate - epidote veining and an odd fracture alteration pattern
-this could be related to adjacent granite or primary feature of massive / pillowed flows
-deformation is extremly strong ptgmatic pattern to the quartz veins
