India hosts remarkably well-preserved volcanic and sedimentary rocks as old as 3.5 billion years, and has similar geologic history to parts of South Africa and Australia, a study has found.
Researchers from the Wits University, the University of Johannesburg (UJ), both in South Africa, and the Chinese Academy of Sciences, examined volcanic and sedimentary rocks from the Daitari greenstone belt in the Singhbhum Craton in east India that were formed approximately 3.5 billion years ago.
Cratons are pieces of ancient continents that formed several billions of years ago. Their study provides a window into how processes within and on the surface of Earth operated in the past.
