Stratigraphy
Geological group:Beaufort Formation:Katberg
Stratigraphic resolution:group of beds
Stratigraphy comments: Botha et al. (2007) considered this part of the Lystrosaurus AZ to be Olenekian; however, this was revised to Induan by MacDougall et al. (2013)
Lithology and environment
Primary lithology:fine,medium sandstone
Secondary lithology:red mudstone
Includes fossils?Y
Lithology description: "The outcrops here consist of fine-tomedium-grained pale olive (10YR6/2) sandstone bodies separated by very dusky red (10R2/2) fissile mudrock. The sandstone bodies have a ‘gullied’ basal contact containing pedogenic glaebules, and scouring of the interchannel facies is evident: both features indicate flash flooding"
Environment:fluvial indet.
