The Pebbly Arkose Formation is a Triassic geologic formation found in southern Africa.
The formation comprises mainly coarse, arkosic sandstones.
The Pebbly Arkose Formation is found in Botswana, Zambia and Zimbabwe, in the Mid-Zambezi, Mana Pools, Cabora Bassa and Limpopo basins.
The Pebbly Arkose Formation is part of the Upper Karoo Group, overlies the Escarpment formation (in the Mid-Zambezi and Limpopo basins) and the Angwa Sandstone Formation (in the Mana Pools and Cabora Bassa Basins) and underlies the Forest Sandstone Formation.
The Pebbly Arkose has been correlated to the Elliot Formation of the Great Karroo Basin, South Africa and the Mpandi Formation of the Thuli Basin in Botswana and Zimbabwe.
