Map showing extent of the Uitenhage Group in the Algoa and Gamtoos Basins
The Uitenhage Group is one of three geological groups, which comprise the onshore and offshore post-Karoo middle to lower Upper Mesozoic geological rock units in South Africa.[1][2][3][4] Stratigraphically, the Uitenhage Group overlies the Suurberg Group and is overlain by the Algoa Group.[5][6] It contains four formations that range in age from late Early Jurassic and late Early Cretaceous in age (~183 - 100 Ma).
