PETROLOGIC DATA

Rock Number: 1

Rock Type: conglomerate
Descriptors:
bedded
pelitic

Field Description:

-contact between chaotic conglomerate and pelitic matrix conglomerate as at previous station
-bedding in pelitic matrix unit poorly defined by variation in clast size in moderatly sorted units garnet, staurolite and fibrous amphibole (probably anthophyllite) very abundant
-chaotic unit as before
-anthophylite most abundant just above contact
-matrix difficult to isolate as it is largely lithic fragment and silt
-staurolite layer bound in general

-samples a and b for anthophyllite, c for garnet-staurolite assemblages

Minerals of Note
Mineral Abundance (%)
