United KingdomResearchers from Curtin University and the Geological Survey of Western Australia have determined the most precise age for the oldest known asteroid impact crater on Earth. The North Pole Dome in the Pilbara region of Western Australia was found to have been created approximately 3 billion years ago, making it the oldest confirmed impact structure on the planet. Using advanced mineral dating techniques, scientists examined zircon and apatite minerals in the area, finding that both indicated the same age for the impact event. This discovery provides important insights into how meteorite impacts influenced Earth's early development, particularly during the Archean eon when the planet's first continents were forming.
