Dunedin dune complexes.

Brewster, Anthony Patrick.

Five beaches around the Peninsula (Tomahawk, Smails, Allans, and Victory Beaches, and Harwood spit) are examined for evidence of recent accretion and erosion, mainly through the use of aerial photographs. They are essentially stable except for Harwood spit which is presently eroding.
Mineralogical and size analyses of the beach and back dune sands are carried out, samples range from 60-85% quartz and are well-sorted.
From the stratigraphy at Okia Flat three apparent dune building episodes are recognized, the last two having occurred since the period 800-1500 AD.
The cause and origin of a substantial sand blow across the Peninsula at Otakau in the 1860's are looked at.
