PETROLOGIC DATA

Rock Number: 1

Rock Type: amphibolite
Descriptors:
layered
hornblende - garnet bearing
Field Description:

-as previous station
-mafic volcanic derived psammitic-textured
-layering is discontinuous chopped up in foliation but fairly continous on a 1 to 2 mm scale
-numerous baudinaged granitic viens and quartz viens
-some showing rolling and augening
-ghis looks like a fairly normal lower cycle mafic seds.

Rock Number: 2

Rock Type: amphibolite
Descriptors:
massive
gabbroic
Field Description:

-salt and peppered textured HB mesogabbro
-appears to be a dike or sill with in seds. that is highly intruded by white pegmatite in an anastimosing network
-highly foliated and baudinaged margin appears sheared on one side and intruded by a dike of schlieric CWB GRDR, this whole outcrop or sed. and gabbro is probably a large scale AGMT in CWB complex
