PETROLOGIC DATA

Rock Number: 1

Rock Type: greywacke
Descriptors:
layered
mafic
Field Description:

-grey weathering feldspathic wacke seems to have both HB and BO
-beds are up to one metre thick with internal cm lamination
-fibrous amphibole, chlorite rosettes, form on cleavage planes
-appears to be quartz poor possibly 15 %
-injected granitically lit contain HB and have HB and BP salvages
-the whole sequence appears to be flattening and swinging into channel direction
-this is probably drapped over the domal edge of CWB complex
-based on composition; part of lower cycle
