A study of diamonds has shed new light on the history of the supercontinent Gondwana, believed to have formed between 800 million and 550 million years ago.
Diamonds that formed deep below the Earth's surface are revealing the secrets of an ancient supercontinent that existed hundreds of millions of years ago.A study of these 'super-deep' diamonds has found that they contain evidence of the rocks that helped buoy and grow the supercontinent known as Gondwana.
But the records of these formation events are poorly preserved.In part, this is because the oceanic crust is young and continually sinks beneath the planet's surface in a process known as subduction. In addition, the continental crust provides only a limited view of what is going on deep beneath the Earth.In the latest study, the researchers examined diamonds found in Brazil and West Africa's Guinea that formed between 300 and 700 kilometers below Earth's surface.
