Australia’s North Pole Dome Crater is Earth’s Oldest and Only Known Archean Impact Structure
Geologists have identified a 3-billion-year-old asteroid impact site at the North Pole Dome in Western Australia. Using advanced mineral dating on zircon and apatite, researchers confirmed this as Earth's oldest known impact structure.
Why it matters
This discovery provides critical data on the early Earth's bombardment history, which has been difficult to study due to the planet's active geological processes.
Zircon crystals and impact-altered minerals show that a massive asteroid slammed into what is now the Pilbara region of Western Australia about 3 billion years ago.
