...EMESE M. BORDY; WILLIAM D. KRUMMECK Abstract An Early Triassic continental ichnofossil assemblage dominated by ∼ 4 cm diameter burrow casts was discovered in the transitional zone of the Katberg and Burgersdorp formations in the SE main Karoo Basin (Eastern Cape, South Africa). Analyses...

... (Stormberg Group) and corresponds to the entire Burgersdorp Formation. It is characterised by the presence throughout of the cynodont genus Cynognathus . The biozone reaches a maximum thickness of around 650 m in the southeast part of the basin and thins dramatically to the north, where it is only a maximum...

Fourteen stratigraphic sections were evaluated in the Balfour and Normandien formations (Lower Beaufort Group), Katberg Formation, and overlying Burgersdorp...

... in the Balfour, Katberg and Burgersdorp formations respectively. This data shows that certain parts of the Beaufort Group stratigraphic succession that are present in the southern part of the Karoo Basin, are absent in the central Free State, indicating either a depositional hiatus or a period of erosion...

Above the Swartberg member the uppermost Katberg Formation fines upwards into the Burgersdorp Formation, which contains the overlying Cynognathus Assemblage Zone ( Neveling, 2004 ).

The second reference quoted by Turner (1999 , Figure 14, p. 231) in support of laumontite in the Burgersdorp Formation (Beaufort Group...

... al. 2002 ), and Neveling (2004) proposed that only the former unit should be correlated with the middle Katberg Formation because the lowermost and uppermost sections of the Katberg Formation are restricted to the proximal part of the basin. The predominantly argillaceous Burgersdorp Formation...

... collecting efforts have been concentrated on this facies. Those of the “impoverished zone” of the upper part of the Katberg Formation and lower part of the Burgersdorp Formation, however, are so poorly fossiliferous that prospecting of intraformational conglomerates is an attractive alternative (J. Neveling...

These assertions indicate that the Escarpment Grit in Zambia must be either equivalent in age or, more likely, older than the Cynognathus Assemblage Zone, that is, similar in age to the Katberg or lower Burgersdorp...

Burrows described there are, however, smaller and more circular in cross section than the Holy Cross burrows. The basic question is what organism...

Thin mudstone beds are present, with red mudstone beds increasing in abundance towards the upper boundary of the formation as it grades into the Burgersdorp F ( Johnson...

Neveling (2004) recognized an upward-thickening and -coarsening trend in the formation, culminating in stacked cliff-forming...
