-SAMPLE
A CWB TNLT
B augen GRDR
PETROLOGIC DATA
Rock Number: 1
-similar relationship exists as previous stations except the components are different
-sample A is a fairly normal CWB white TNLT
-sample B is an augen GRDR similar to Whiskey Jack Complex
-the intrusive relationships between the two units appear contradictory
-in some inclusions, A includes B and the reverse in others
-this confusion I believe to be structurally imposed
-I would interpret this outcrop as augen GRDR intruding CWB TNLT
-the TNLT is a schlieric gneiss with granitic lit and grey GRDR layers
