The Flood Revisited I

This years flooding of northern Australia and the Arnhem Land sandstone plateau is nothing new.

In the mid-Proterozoic, about 1 billion years ago, huge deposits of fluviatile sediments covered much of the region and now form the relatively flat-bedded sandstone plateaus which, with their escarpments, dominate the landscapes of Kakadu, the Kimberly and Cape York. These sandstones have all the expected features of shallow water deposition: cross-bedding, ripple marks, mud cracks and rain prints. The theory it seems is that these sands were deposited in vast river deltas which over time took many different courses over northern Australia.
