Study Reveals Ancient Tropical Sea Covered Parts of Assam During Eocene Epoch
Researchers from Nagaland University have revealed that parts of present-day Assam, specifically the Karbi Anglong district, were once covered by a warm, shallow tropical sea around 50 million years ago during the Eocene Epoch. Their study of the Sylhet Limestone formations at Dillai Parbat used fieldwork and laboratory analyses to reconstruct this ancient marine environment, identifying diverse microscopic marine life, fluctuating sea levels, and tectonic influences. The findings, published in the Journal of Geosciences Research, provide new insights into Northeast India's geological history.
