India has Similar Geologic History to Parts of South Africa & Australia

A study has found that India has a similar geologic history to parts of South Africa and Australia. In this article, you can learn more about the study, its findings and also about the Daitari Greenstone Belt for the IAS exam.

Study on India’s Geological History Findings

Indian volcanic and sedimentary rocks, some of which are 3.5 billion years old, are remarkably well preserved.

• Researchers looked at volcanic and sedimentary rocks from the 3.5 billion-year-old Daitari Greenstone Band in the east Indian Singhbhum Craton.
• Cratons are fragments of former continents that broke off from the Earth many billions of years ago.
• Their research provides a window into the historical operation of processes within and on the surface of Earth.
• The study provided significant geological timelines that show the Daitari greenstones’ tectonic development.

Daitari Greenstone Belt

The Daitari Greenstone Belt (DGB) is located in the south of the Singhbhum Craton. 

• The belt shares a similar geologic makeup when compared to the greenstones exposed in the Barberton and Nondweni areas of South Africa and Australia.

Significance of the Study

• It’s crucial to study ancient greenstones because they preserve minor sedimentary rocks that originated in sub-marine environments and help us comprehend the various volcanic processes.
• These volcanic-sedimentary rocks serve as time capsules for the evolution of the planet in its early stages and reveal information about habitable habitats on the primordial Earth.
• The study suggests that geologically similar techniques may have been applied to these ancient continents 3.5 billion years ago.
