World's Oldest Known Impact Crater Discovered in Western Australia
The 3.47-billion-year-old crater provides new insights into Earth's early history and the conditions that may have fostered the origins of life.
- Geologists identified the 3.47-billion-year-old crater, named North Pole Crater, near Marble Bar in the Pilbara region of Western Australia.
- The discovery surpasses the previous oldest known crater, Yarrabubba, by more than 1 billion years, providing a rare glimpse into Earth's ancient impact history.
- The crater's formation was confirmed by the presence of shatter cones, unique geological features formed under extreme pressure from meteorite impacts.
- Scientists suggest the impact may have influenced early Earth's crust formation and created environments conducive to microbial life, such as hot water pools.
- The findings highlight the potential for uncovering more ancient craters, which could reshape our understanding of Earth's evolution and early life.
