PETROLOGIC DATA

Rock Number: 1

Rock Type: sandstone
Descriptors:
trough cross-bedding
lithic

Field Description:

-same sequence of trough cross bedded yellow brown wackes-quartz rich (55%) with dominant lithic fragment matrix 1 to 3% quartz granules
-cross beds average 30 cm thick with aberage 195 cm length at 2 to 5 degree angles (after attenuation)
-trough pebble fill is dominantly sediment clasts with <5% granitoid-probably unit (1) 15 to 20% mafic clasts and mudstones
-no iron formation clast noted
