Abstract

Sedimentary structures in a sandstone in the Weald Clay are described. They are groove casts, possibly formed by plant fragments being moved by water, air-heave structures, scour structures, load casts, syndepositional faults and folds, trace fossils and ripple structures. From their study it is concluded that the sandstone was deposited by the sudden inrush of sediment-laden water; and a comparison is suggested with the crevasse sands of modern deltas.
