- •
Five bedded clastic facies associations have distinct composition and grain size.
- •
Bedded clastic facies contain zircons dated at 1600 Ma, 1740 Ma, 1900 Ma and 2500 Ma.
- •
Fold axes of pre-lithification folds plunge gently to the northeast.
- •
Structure and facies suggest deposition in a fault-controlled sedimentary basin.
