-contact between chaotic conglomerate and pelite matrix staurolite-garnet-sillimanite conglomerate which is in contact on south with thin wedge of moderatly sorted cobble conglomerate with thin sand horizons
PETROLOGIC DATA
Rock Number: 1
-this unit, unlike that to NE does not have abundant mafic clasts or hornblendic matrix to the same extent although it is generally more hornblendic then chaotic unit
-the contact is gradational over 1.5 m with clast size gradually increaseing from the 2x5 cm sorted clasts of the pelite matrix conglomerate into a cobble to border conglomerate
-rare lithic arenite beds (5 to 15 cm ) in pelite
-samples of ST bearing pelitic conglomerate with large staurolite poikiloblasts
-some staurolite is 1.5 x 5 cm
