Geology

The Lower Karoo corresponds to the lower portion of the Karoo Supergroup sequence. The basal unit comprises glacial tillites,^[1] being the Dwyka Formation in the Mid-Zambezi Basin, Basal Beds in the Limpopo basins^[2] and Kondo Pools Formation in the Mana Pools and Cabora Bassa Basins.^[3] These are overlain in the Mid-Zambezi by the Wankie sandstones and coal and the Madumabisa Mudstone^[1]

It is overlain and overstepped by the Upper Karoo Group.^[1]

In the Mana Pools and Cabora Bassa Basins, the Kondo Pools Formation is overlain by the Mkanga Formation sandstone and mudstones.^[4]
