A crater-like impact structure in outback Western Australia, known as North Pole Dome, is described as Earth’s oldest confirmed impact site. The Conversation reports that a new study confirms the structure’s age as more than 3 billion years old, placing it among the earliest impact records preserved on the planet. The finding focuses on the crater’s origin and timing, arguing it results from an asteroid impact rather than another geological process.
New Scientist discusses the same overall claim and notes that while some research supports an age of roughly 3 billion years, there has been dispute among researchers about the proposed timing. The differing views reflect challenges in dating very ancient geological formations and interpreting the evidence preserved in the region.
Taken together, the reporting indicates that North Pole Dome is widely considered an ancient candidate for Earth’s oldest impact structure, and that recent work strengthens the case for an age exceeding 3 billion years, even as some scientists continue to question or refine the interpretation and dating.
