Earth's oldest impact crater was just found in Australia—exactly where geologists hoped it would be
We have discovered the oldest meteorite impact crater on Earth, in the very heart of the Pilbara region of Western Australia. The crater formed more than 3.5 billion years ago, making it the oldest known by more than a billion years.
The discovery of a 3.47-billion-year-old crater in WA's Pilbara region pushes back the age of the earliest-known impact site on Earth by more than one billion years.
The crater, located near the Pilbara town of Marble Bar, is thought to have been created 3.47 billion years ago.
