Clast elongation lineation pitches 89 degrees east in the schistocity
-interlayered sequence of lithic wackes and highly deformed conglomerates
-metamorphic grade appears to be almandine amphibolite facies with numerous faser kiesel in the wacke beds

PETROLOGIC DATA

Rock Number: 1

-variable bed thickness from 15 to 130 cm with cross beds common
-rare scour channels
-high quartz content-60 to 65% with numerous grey quartz granules
-calcsilicate layers common with fine amphibolite and 3 to 4mm GR blasts
-calcsilicate as layers or anastomosing patches

Minerals of Note

Mineral	Abundance (%)
garnet
sillimanite

Rock Number: 2

-beds up to 2.5 m
-numerous small scours
-clast supported in general but may have some matrix supported beds
-clasts types dominated by sediments but may have significant mafic clast component
-rare bull quartz clasts
-one layer contains several clasts of iron formation
-one clasts of granodiorite appears to have weathering rind
-also present are felsite, granite, tonalite, quartzite and intermediate wacke clasts
