Planation surfaces of Australia

Abstract

The author disagrees with L. King's opinion on the most widespread «Australian» planation surface being of Early Cenozoic age. The «Australian» surf ace was formed in Late Jurassic-Early Cretaceous, remnants of the Middle Triassic surface are above it and Middle Eocenic and Miocenic erosional and aggradational surfaces are situated at lower levels (within area of loose Mesozoic and Cenozoic sediments). Number and age of the planation surf aces in Australia correspond to those in Europe and Asia, the fact is accounted for by the connection of global eustatic ocean transgressions with planationsurface formation.
