  • The Bungle Bungle Mountains are an unusual and very dramatic plateau of Devonian quartz sandstone (approximately 360 million years old), created through a complex process of sedimentation, compaction, uplift (caused by the collision of Gondwanaland and Laurasia approximately 300 million years ago and the convergence of the Indo-Australian Plate and the Pacific Plates 20 million years ago), as well as long periods of erosion.

    Purnululu National Park, Australia

  • Hundreds of millions of years ago, there were two supercontinents, Laurasia (North America, Europe and Asia) and Gondwana (everything else).
