PETROLOGIC DATA

Rock Number: 1

Rock Type: tonalite
Descriptors:
porphyritic
biotite
Field Description:

-excellent exposure of fairly coarse and definetely PORT CWB TNLT
-preservation of the PORT texture seems to have been enhanced by the sheltering effects of large supercrustal rafts

Rock Number: 2

Rock Type: greywacke
Descriptors:
layered
volcanic derived
Field Description:

-well laminated MAFIC SNDS and siltstones
-probably derived from mafic volcanic's
-there are also inclusions in the TNLT of MASS BSLTic ampb probably massive flows
-the inclusions are caught up in the MT layering direction and schlieric layering direction of the TNLT
-TNLT occurs as boudinaged dikes in the super crustals

Minerals of Note

garnet
epidote
