... this boundary. The Estcourt Formation previously was interpreted to be part of this group representing shallow bay fill, the result of overbank deposition. This interpretation implies that sedimentation occurred along the margins of a large, shallowing basin during the Late Permian. Recent work in a series...

The Formation is considered a stratigraphic equivalent of the Normandien Formation (and informal Estcourt Formation) of the eastern and north-eastern, and the Balfour Formation...

... Province, the rocks have been equated to the Estcourt Formation. The Katberg Formation (Scythian; Catuneanu et al., 1998 ), with a maximum preserved thickness of 1200 m ( Groenewald, 1996 ), has been placed stratigraphically just at ( Ward et al., 2000 ) or above ( Smith, 1995 ; Retallack et al., 2003...

... Permian paleosols of the central Karoo Basin are equivalent in age to the Estcourt Formation, a sequence of coal measures formed in more humid paleoclimate to the northeast in Natal, for example, near Bulwer. The flora of the Estcourt Formation includes a variety of Glossopteris leaves, which are small...
