Finding Argoland: How a lost continent resurfaced (phys.org)
Geologists have long known that around 155 million years ago, a 5,000 km long piece of continent broke off western Australia and drifted away. They can see that by the ‘void’ it left behind: a basin hidden deep below the ocean known as the Argo Abyssal Plain. The underwater feature also lends its name to the newly formed...
What's the deepest-occurring gemstone on Earth? (www.livescience.com)
How diamonds form still isn’t entirely understood, but laboratory experiments show that the gemstones crystallize only under extreme pressures. Most naturally occurring stones have been traced to the upper mantle, at depths between 93 and 186 miles (150 to 300 km), where pressures can reach beyond 20,000 atmospheres....

Impact melt breccia (grey) and upthrust rocks (brown). The breccia is interesting because the melt was a carbonate. So it’s sort of like a carbonatite lava.

Australia and Arizona rock layers
Does Arizona and Australia share the same rock formation layers? I was watching a TV show and a lot of the Australian landscaped looked very red and similar to Sedona Arizona. Do they share the same layers?
