Geology

Description

The formation comprises mainly coarse, arkosic sandstones.[1]

Extent

The Pebbly Arkose Formation is found in Botswana, Zambia and Zimbabwe, in the Mid-Zambezi, Mana Pools, Cabora Bassa and Limpopo basins.

Deposition

Age

Stratigraphy

The Pebbly Arkose Formation is part of the Upper Karoo Group, overlies the Escarpment formation (in the Mid-Zambezi and Limpopo basins)[2] and the Angwa Sandstone Formation (in the Mana Pools and Cabora Bassa Basins)[3] and underlies the Forest Sandstone Formation.[4]

The Pebbly Arkose has been correlated to the Elliot Formation of the Great Karroo Basin, South Africa[4][5] and the Mpandi Formation of the Thuli Basin in Botswana and Zimbabwe.[6]
