Stormberg Gr

It unconformably or conformably overlies the Beaufort Gr (or a Middle Triassic hiatus)

It is capped by the Drakensberg basaltic lavas.

Because the Karoo basins became increasingly fragmented and influenced by local rifting during the Late Triassic, the Stormberg Group takes on various local names across south-central Africa. Western & Namibian Basins - Waterberg Basin: Represented by the Etjo Fm, consisting of aeolian sandstones equivalent to the Clarens Fm. Huab Basin: Represented by the Twyfelfontein Fm (extending into the Early Cretaceous). Kalahari Basins (Botswana) - SW Kalahari: Dondong Fm (fluvial) and Nkalatlou Fm (aeolian). Central/NE Kalahari: Mosolotsane Fm (fluvial sandstones/mudstones) and Ntane Fm (aeolian sandstones). Limpopo Area (Northern South Africa) - Springbok Flats: Irrigasie Fm (spanning Beaufort/Stormberg) and Clarens Fm. Tshipise / Tuli Basins: Klopperfontein, Bosbokpoort, and Red Rocks/Tshipsie members transitioning into the massive Clarens aeolian sandstones. Zambezi & Cabora-Bassa Basins (Zimbabwe/Zambia/Mozambique) - Mid-Zambezi: Initiates with the coarse Escarpment Grit (Early Triassic tectonic pulse), followed by the Ripple Marked Flagstone and culminating in the aeolian Forest Sandstone Formation. Cabora-Bassa: Angwa Sandstone, Pebbly Arkose, and Forest Sandstone. East-Central Africa Extensional Basins- Luangwa (Zambia): Escarpment Grit, Ntawere Fm, and the Red Marl / Upper Grit units. Metangula (Mozambique): Tende Fm and Lipirichi Fm. Morondava (Madagascar): The entire Isalo Gr (Late Triassic to Jurassic coarse sandstones and conglomerates) represents the Stormberg equivalent as Madagascar began to separate from Africa. Congo Basin (DRC): Referred to simply as the "Red Sandstone" unit (Late Triassic fluviatile deposits). Ruhuhu Basin (Tanzania): Absent. The Karoo succession in the Ruhuhu Basin terminates in the Middle Triassic with the Beaufort-equivalent Manda Beds; Stormberg equivalents were either never deposited or entirely eroded.
