Scientists in Australia find ‘smoking gun’ evidence of world’s oldest meteorite strike
Curtin University researchers use innovative techniques to date three-billion-year-old impact crater in Western Australia’s Pilbara region
A meteorite that struck Earth three billion years ago left behind a “smoking gun” – evidence of the world’s oldest impact crater in a remote part of Australia.
Ancient rocks in Western Australia’s Pilbara region record the event, which occurred during the Archean eon, a period 4 to 2.5 billion years ago, when tectonic plates were beginning to form and early life emerging.
