| Local section: | Aloes Siding | Local bed: | 44 m | ||
| Local order: | bottom to top | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Alexandria Formation, which unconformably overlies Late Cretaceous Sundays River Fm in places, and is overlain by eolian calcarenites. AGE: Much discussed, although not clearly in text, to range from Miocene to Pleistocene, but also possible Eocene (see Haughton pers. comm., cited in text). Assigned here to a Pliocene age, based on more recent publications (King, 1972). STRATIGRAPHIC POSITION: A composite list representing the entire formation. | |||||
