The Upper Karoo Group is a sequence of Triassic to Early Jurassic sedimentary and volcanic rocks found in Botswana, Zambia, and Zimbabwe.
It comprises the Escarpment Grit (in the Mid-Zambezi and Limpopo basins) and the Angwa Sandstone (in the Mana Pools and Cabora Bassa Basins), overlain by the Pebbly Arkose Formation and the Forest Sandstone, capped by Batoka Formation basalts.
