Credit: TED MEAD / Getty Images Earth is an amazing planet. As far as we know, it’s the only planet in the universe where life exists. It’s also the only planet known to have continents: the land masses on which we live and which host the minerals needed to support our complex lives.

Date Time WA scientists shed light on continent formation Research from Western Australian scientists has shed new light on how the Earth’s first continental crust was formed. The team of scientists, which included Dr Laure Martin and Mr Matvei Aleshin from The University of Western Australia and was led by the Geological Survey of Western Australia and Curtin University, measured compositions of oxygen in ancient granites in the Pilbara using the ion microprobe Cameca IMS1280 at UWA.
