Abyssal marine sediments

Abyssal marine sediments, originally laid down in the mid-Pacific 200 to 300 million years ago then ferried by currents in the Earth's mantle and plastered against the edge of the ancient Australian continental raft. In the enormous heat and pressure of this process they crumpled like old newspaper. Modern wave erosion has re-exposed these metasediments.
