How did Uluru form?

Uluru is the most iconic natural landform in Australia — and its formation is an equally special story of creation, destruction and reinvention.

It isn’t really new news.

“The newly-formed Petermann Ranges were similar in size to the French Alps or the Himalayas. But without any plant cover they eroded rapidly.”

“We had these high mountains with granite outcropping and shedding of conglomerates which ended up being the rock type that we see at Kata Tjuta,”

Yes. There was a TV program about this.

The Petermann Ranges in central Australia used to be enormous.

Yeah the alps and the Himalayas are famous for their plant cover. Or is it they are the more recent uprisings Australia being famously inert volcanically.

the alps and himalayas do have plants, the early australian ranges didn’t cos plants weren’t invented when they were around.

Yeah yeah, we get the joke. The Alps and Himalayas are enough rapidly too. But they’re still rising because of plate tectonics.

The way I understand it is that Australia’s soils are impoverished due to lack of recent (geolically) volcanic activity and rains washing into the seas.

Bloody spell checker again. Eroding.

victoria and SA has had fairly recent volcanic activity. But the rest of Aus is pretty washed out. the whole GDR is volcanic

There was no volcanic activity near Uluru. More eastern and south eastern coast in recent enough memory

I thought Uluru was the navel-like remains of where the Moon snapped off from the Earth a few billion years ago?

They are impoverished because they are amongst the oldest. washed and rewashed resedimented and compacted over many millennia.

Actually, I have news on that. The Torres Straight Islands are scheduled for more volcanic activity soon. A chain of volcanoes heading south is heading into the Torres Straight Islands from PNG.

There’s some pretty young volcanoes in Qld too.
