 There are no outcrops or exposures of the Stormberg Group East of 24ºE.This was because orogenic loading in the south by the Gondwanide mountains from the early Triassic caused changes in position of the forebulge and foredeep in the foreland basin system.This resulted in the deposition zones shifting to the eastern and northeastern regions of the Karoo Basin from the Early Triassic until the Early Jurassic, when the Drakensberg Group volcanics commenced.
