The Lamington National Park is located on the northern side of the Tweed volcano.
This large shield volcano is over 100 kilometres in diameter, and extends from Tamborine Mountain in the north to Lismore in the south.
The volcanic plug of Mount Warning marks the centre of the volcano.
This volcano was active around 23 million years ago when this part of Australia was above a hotspot in the mantle.
Both basaltic and rhyolitic lavas were erupted, and erosion of these lavas from rain and running water has formed the many spectacular landforms including cliffs, now observed in the park.
Under these layers is a layer of tuff made from volcanic ash and fine rock which is up to 60 metres (200 ft) thick in some places.
The basalts of the Lamington Plateau originate from the Focal Point volcano.
Near Binna Burra the maximum thickness of the basalt layer is estimated to be 700 metres (2,300 ft).
