The age and correlation of the Postmasburg Group, southern Africa: Constraints from detrital zircon grains
Age determinations were conducted on detrital zircon grains from two stratigraphic levels in the Postmasburg Group, Transvaal Supergroup - the top of the Makganyene Formation and the base of the Hotazel Formation - to constrain the age of the group and for comparison with purported correlatives in the Segwagwa Group of the Kanye basin and Pretoria Group of the Transvaal basin. Detrital zircon grains are interpreted as being derived mainly from the underlying Ghaap Group and its basement of...[Show more]
