Follow on with George as he explores something called Liesegang bands and the geology behind the twisty formations.
Liesegang bands are layers formed when new minerals grow out of groundwater. They can create flat layers, or circles which are called Liesegang Rings. An amazing 20 million year old example of this can be found on Madgwick Drive in Armidale, on the way into UNE.
