The Stormberg Group is one of the four geological groups that comprises the Karoo Supergroup in South Africa. It is the uppermost geological group representing the final phase of preserved sedimentation of the Karoo Basin. The Stormberg Group rocks are considered to range between Lower Triassic to Lower Jurassic (Pliensbachian) in age.
Stratigraphic units in this group include (from oldest to youngest): Enon Formation: Contains subordinate sandstones and different types of thickly-bedded conglomerates, which consist mainly of quartzite and sometimes slate, shale, and charcoal. The clasts are poorly-sorted, sub-rounded to rounded pebbles and cobbles.
The Waaipoort formation has most commonly been interpreted as a marginal marine environment, possibly a lagoon or a delta.The fauna, composed mostly of paleoniscoids, is a large divergence from the predominantly placoderm- and sarcopterygian- dominated faunas of previous Witteberg Group formations like the Witpoort Formation.
Karoo National Park near Beaufort West, Western Cape Province, South Africa. The geological formations of the Beaufort Group are outcrop over approximately 145 000 km 2, attaining a total thickness of around 6000 m thick at its thickest outcrops. In the west, the lowermost Beaufort Group rocks are found east of Laingsburg and remain continuous ...
The geology of South Africa is highly varied including cratons, greenstone belts, large impact craters as well as orogenic belts. The geology of the country is the base for a large mining sector that extracts gold , diamonds, iron and coal from world-class deposits.
The Clarens Formation is a geological formation found in several localities in Lesotho and in the Free State, KwaZulu-Natal, and Eastern Cape provinces in South Africa.It is the uppermost of the three formations found in the Stormberg Group of the greater Karoo Supergroup rocks and represents the final phase of preserved sedimentation of the Karoo Basin.
A mountain in the Tanqua Karoo, South Africa, with multiple layers of turbidites formed in the south-western portion of the Karoo Sea about 300 million years The rocks of the Ecca Group first appear near Sutherland in its westernmost deposits, and continues east through Laingsburg , Prince Albert , Jansenville , Grahamstown , and up until the ...
