Rock Type: conglomerate
Descriptors:
bedded
polymictic

Field Description:

-interbedded conglomerate in SNDS
-CGLM is clast supported PBBL CGLM that shows no grading but is sorted by beds, probably large scale trough deposits
-sed. clasts dominate, particularly grey siltstone and SNDS
-volcanic clasts are present in the small pebble size
-quartz clasts are common perhaps as much as 1%
-there are very few granitic clasts
-occurs in 1 to 2 m horizons made up of BO-50 cm beds
