'Australian volcanoes threw debris over 2300 km'
A study has revealed volcanic eruptions in eastern Australia around 100 million years ago, were so powerful they blasted sand-sized zircon crystals from one side of Australia to the other, almost 2,300 km away. It was found that the crystals didn't match any rock composition​ in Western Australia, but reflected eastern Australia's volcanic rock in terms of age and geochemicals.
