Sedimentology and taphonomy of the upper Karoo-equivalent Mpandi Formation in the Tuli Basin of Zimbabwe, with a new 40Ar/39Ar age for the Tuli basalts

New data on the palaeontology and sedimentology of the Lower Jurassic Lisbon Formation (Karoo Supergroup), Ellisras Basin, South Africa

“…WRIGHT & MARRIOTT 2007). Similar environmental interpretation was also possible for the above mentioned lithostratigraphic correlatives of the Lisbon Formation (BORDY & CATUNEANU 2001;BORDY et al 2004 a;ROGERS et al 2004).…”

“…The Lisbon Formation shows striking lithological and stratigraphic similarities to the upper Elliot Formation in the main Karoo Basin (BORDY et al 2004 a) as well as to the red bed succession (i. e., Bosbokpoort Formation and Red Rocks Member of the Clarens Formation of South Africa; Mpandi Formation in Zimbabwe) of the neighbouring Tuli Basin (Fig. 1) (BORDY & CATUNEANU 2001;ROGERS et al 2004). The lithological correspondence is due to the similar facies architectures including dominance of red beds; similar mean grain sizes and sedimentary structures; abundance of in situ pedogenic nodules; bonebearing, pedogenic nodule conglomerates, etc.…”

Surface texture analysis of southern Tuli Basin sediments: Implications for Limpopo Valley geoarchaeological contexts

“…The Tuli Basin trends roughly east-west for about 300 km and occupies the border region of Botswana, South Africa and Zimbabwe (Rogers et al, 2004) (Fig. 1).…”

“…Although the basin comprises igneous and sedimentary rocks of the Late Carboniferous-Middle Jurassic Karoo Super Group, the Tuli sequence is less continuous and thinner (max $450-500 m) than that of the main Karoo Basin (Bordy and Catuneanu, 2001). The Tuli Basin is thought to represent the western down-dropped arm of an unsuccessful rift triple junction, linked to the break-up of Gondwanaland, that eventually extended north-south from the Save Basin in Zimbabwe to the Lebombo Monocline in South Africa and Mozambique (Bordy and Catuneanu, 2001;Rogers et al, 2004).…”

Grain-size characteristics of surface sands and sandstones: indicators of potential sediment sources for the southern Tuli Basin, South Africa

“…The Tuli Basin trends roughly eastwest for about 300 km and surrounds the border region of Botswana, South Africa and Zimbabwe (Rogers et al 2004). The basin is filled by igneous and sedimentary rocks of the Late Carboniferous -Middle Jurassic Karoo Supergroup.…”
