Angwa Sandstone
The Angwa Sandstone is a geological formation of the mid-Triassic Cabora Bassa Basin and Mana Pools Basin of southern Africa, consisting mainly of sandstone.

Description

Stratigraphy 
The Angwa Sandstone is the lowest formation in the Upper Karoo Group of the Karoo Supergroup, underlying the Pebbly Arkose Formation and overlying the Lower Karoo Group. The formation is divided into two members: the Alternations Member and the Massive Sandstone (Chirambakadoma) Member.

The Angwa Sandstone has been correlated to the Molteno Formation of the Great Karoo Basin, South Africa, and to the Escarpment Grit of the Mid-Zambezi Basin.

Lithology 
The formation is a sedimentary unit, consisting mainly of fluvial sands and silts.

It has been dated as covering rocks from much of the Triassic, with pollen and flora identified from the Induan, and Ladinian  to Norian.

Occurrence 
The Angwa Sandstone Formation is found in Mozambique, Zambia, Zimbabwe, in the Mana Pools and Cabora Bassa Basins.
