- Lower Karoo Group, comprising the Dwyka, Hwange (Zimbabwe) / Siankondobo (Zambia) and Madumabisa formations.
- Upper Karoo Group, comprising the Escarpment Grit formation (in the Mid-Zambezi and Limpopo basins) and the Angwa Sandstone Formation (in the Mana Pools and Cabora Bassa Basins), overlain by the Pebbly Arkose Formation and the Forest Sandstone Formation, capped by Batoka basalts.
