Kimberley Sand Stone Layers

This area is around the corner from the famous Horizontal Waterfalls and is an excellent example of the timeless Kimberley geology.

The origin of the rocks that make up the landscape of the Kimberley is very complex.
Volcanic activity with outpourings of lava has formed basalt, while intrusions of magma (molten rock) beneath the land’s surface have formed granites and dolerites – now exposed in places by erosion.
Sediments weathered from rocks have accumulated in immense basins producing sedimentary rocks such as sandstone, conglomerate and siltstone.

The subsequent retreat of the sea and the uplifting of the land now belie their origins. Movements within the earth’s crust have buried volcanic and sedimentary rocks at depths of up to 20 kilometres in the Earth’s crust and the resultant heat and pressure have produced metamorphic rocks such as schist and gneiss.

The result is what we are looking at here, these multi coloured layers that rise up out of the ocean!

  1. OK now it's my turn to impress with geology. I think I mention whilst on TN (did I mention how specky that was) that the Buccaneer Archipelago and McLarty Range (your pic) is also part of the King Leopold and Durack Range system which stretches from your pic in an arc around the southern and eastern Kimberley to Kununurra. This belt of ranges is where the Kimberley Plateau crashed into the rest of Australia. Hence the change in geology from about Raft Point around to Wyndham.

  2. Good ol' Cyclone Creek! We used to tell people that this area was the crumple zone of Western Australia. Flying over this area is even more amazing!
