A detailed study of the sedimentary structure and geographical extent of a prominent and widespread sandstone unit in central Australia reveals evidence of high energy depositional processes. The sheet-like nature of the Heavitree Quartzite indicates that an abundant supply of sediment was deposited and distributed in a high-energy, shelf-like environment. The extent of the sedimentary formation indicates that the depositional process represented a cataclysm of continental scale. Abundant sediment supply was transported to the flat, shallow depositional basin by wide flowing rivers. The sediments were laid down rapidly throughout the basin by high-energy water flows associated with the shallow marine environment of the basin, and by rapid changes in relative sea level. In the early stages of deposition strong reversing tidal currents played a major role in dispersal, but as water depths increased unidirectional currents became dominant. These findings from sedimentological analysis are indicative of the types of depositional environments expected during the early phase of Noah’s Flood.That geology rocks!
