Stratigraphy
Formation:Alexandria
Local section:St. George's Strand Local bed:39 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.
