Basis of coordinate:stated in text
Geographic resolution:outcrop
Time
Period:Neogene Epoch:Pliocene
10 m.y. bin:Cenozoic 6
Key time interval:Pliocene
Age range of interval:5.33300 - 2.58000 m.y. ago
Stratigraphy
Formation:Alexandria
Local section:Coega Local bed:60 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.
Lithology and environment
Primary lithology:shelly/skeletal sandstone
Includes fossils?Y
Lithology description: Two Cypraea zietsmani specimens were found in a coquinite layer that had been deposited as a beach berm.
Environment:foreshore
Geology comments: The high wave energy that existed during the deposition of this shelly layer is suggested by the fragmented and worn nature of the fossil shells.
