What’s Australia made of? Geologically, it depends on the state you’re in
We think of Australia as a solid landmass. But it’s actually more like a jigsaw puzzle that has been put together over many millions of years.
The problem with working out how Australia formed is that the evidence is often buried, making access to geological materials quite difficult.
But now new techniques, new drill holes and the reevaluation of older samples are reshaping our understanding of how and when Australia formed.
