| Stratigraphy comments: "Subzone B of the Cynognathus Assemblage Zone, Beaufort Group, Middle Triassic (Anisian)." (Modesto & Damiani, 2003). This biostratigraphic assignment corresponds to the Burgersdorp Formation (see Catuneanu et al., 2005, J. African Earth Sci. 43). | |||||
Lithology and environment
| Primary lithology: | concretionary,red "siliciclastic" | ||
| Environment: | dry floodplain | Tectonic setting: | foreland basin |
| Geology comments: The Burgersdorp formation was "deposited on a semi-arid, slowly aggrading floodplain drained by sluggish meandering stream channels, which supplied water and sediment to the pedogenically-influenced overbank environments via crevasse splays (Hancox, 1998). Lakes and ponds developed on the floodplain [...]" (Catuneanu et al., 2005, J. African Earth Sci. 43). | |||
