Popis:	Detailed mapping of the Hardey Syncline region at the Marra Mamba Supersequence Package closure, in the southwestern part of the Hamersley Province, has indicated that a hiatus in parts of the Jeerinah Formation was probably caused by submarine slumping during sedimentation. A similar hiatus at the base of the Jeerinah Formation farther west, noted on air photographs, is attributed to the same cause. Removal by slumping, and redeposition westwards, could account for olistostromes which were previously recorded in the Jeerinah Formation at Mt Edith and Mt de Courcey on the southern rim of the Wyloo Dome.
