How was the bungle bungle range formed?
About 375-350 million years ago during the Devonian period, sandstone and conglomerates were deposited in the Ord Basin to create a plateau. Over the last 20 million years the… plateau has been eroded to by water runoffs, wind, sand movent and plants and animals on and around the Bungle Bungle Range to form the dome shaped formations that are around today. Location of the Purnululu National Park The Bungle Bungles look a bit like bees with orange and dark grey banding on them. The dark grey banding on them is caused by sandstone with lots of clay that has a protective layer of cyanobacteria which is blue-green algae which can survive the heat in the areas. The orange banding is caused by sandstone with not much clay and has a protective layer of iron oxide that is only a few millimetres thick. They both protect the soft clay based sandstone underneath and also slow weathering and erosion. (MORE)
