Rock Number: 1

Rock Type: granodiorite
Descriptors:
schlieric or schlieren present

Field Description:

-pinkish grey weathering with a grey fresh surface

-good CWB camp style
-several late, generally plane 10 to 40 cm red potassic peg. with well developed quartz cores
-there are nebulus areas of the EP bearing, slightly mega, grey TNLT
-it is difficult to decide weather the TNLT intruded or is included in the GRDR as cataclasis has destroyed the contact relationships
