The formation comprises mainly gritstones and coarse sandstones.
Stratigraphy
The Escarpment Grit Formation is the basal unit of the Upper Karoo Group[1] and the and underlies the Pebbly Arkose Formation.[2]
The Pebbly Arkose has been correlated to the Angwa Sandstone Formation in the Mana Pools and Cabora Bassa Basins[3]and the Elliot Formation of the Great Karroo Basin, South Africa[2][4]
