Scientists from Hyderabad's National Geophysical Research Institute (NGRI) discovered a historic collision between India and East Antarctica over a billion years ago, revealing a hidden ridge in Andhra Pradesh’s Darsi and Addanki regions.
By reprocessing seismic data along a 325-kilometer profile, the team identified a thin layer of alluvium underlain by Gondwana sediments and Proterozoic sedimentary layers, indicating significant geological shifts.
The findings, published in the Journal of Pure and Applied Geophysics, provide new insights into the evolution of India's eastern coast and its ancient ties to Antarctica, enhancing the understanding of the region's geological history.
