Stratigraphy
| Formation: | Angahook | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Angahook Fm, which regionally conformably overlies the Anglesea Mbr of the Demons Bluff Fm, which in turb may be correlaed with the Browns Creek Clay and the Glen Aire Clay. Stratigraphy is discussed by Raggatt and Crespin (1955). AGE: The age of the assemblage is Late Oligocene and is immediately pre-Janjukuan. STRATIGRAPHIC POSITION: From basal 4 m of the Angahook Fm. | |||||
