High up in the Himalayas, researchers from the Indian Institute of Science (IISc) and Niigata University in Japan have found water droplets trapped in mineral deposits, likely remnants from an ancient ocean that existed approximately 600 million years ago. Through an examination of the deposits, containing both calcium and magnesium carbonates, the team was able to propose a potential explanation for occurrences that might have led to a major oxygenation event in Earth’s history.
