By reprocessing seismic data along a 325-kilometer profile from Alampur to Ganapeswaram, the team investigated the subsurface crustal seismic structure of the north Cuddapah basin. Their findings revealed a thin layer of alluvium underlain by Gondwana sediments and Proterozoic sedimentary layers. Gondwana, a supercontinent encompassing present-day South America, Africa, Arabia, Madagascar, India, Australia, and Antarctica, played a crucial role in the geological evolution of these regions.
“Our research has uncovered extensive Proterozoic sedimentation in the study region,” shared the NGRI scientists with TOI. “We have identified both upper and lower Proterozoic Cuddapah sediments directly overlying the crystalline basement. This provides new insights into India’s eastern coast’s geological history during the Proterozoic era.”
Published in the ‘Journal of Pure and Applied Geophysics,’ this study marks a significant contribution to understanding the ancient geological events shaping the Indian subcontinent and its connections with Antarctica.
