Researchers from Curtin University have uncovered evidence of the world’s oldest known meteorite impact crater, located in the Pilbara region of Western Australia.
The discovery was made while studying the rock layers of the North Pole Dome, a geological formation in the area. According to the team, the impact occurred approximately 3.5 billion years ago, making it the earliest known evidence of a meteorite collision on Earth.
The findings provide crucial insights into the planet’s early history, shedding light on the conditions that prevailed when Earth was still in its formative stages. This ancient impact could also offer valuable clues about the early environment of Earth, including its atmosphere and the potential for life during that period.
The North Pole Dome area, known for its unique geological features, is now regarded as one of the most significant locations for studying Earth’s early impacts and its geological evolution. The research, which adds to the growing body of knowledge about Earth’s early history, is expected to help scientists better understand the role of meteorite impacts in shaping the planet’s surface and possibly influencing the emergence of life.
This extraordinary discovery is a reminder of the powerful forces that have shaped Earth over billions of years and highlights Australia’s critical role in the study of ancient impacts.
