Scientists from the Geological Survey of India have discovered millions of tonnes of precious minerals and metals deep under the waters surrounding the Indian peninsula, The Times of India reported on Monday. The GSI complied the data after surveying 1,81,025 square kilometres of seabed.
Indian research vessels Samudra Ratnakar, Samudra Kaustabh and Samudra Saudikama carried out the exploration named “High Resolution Seabed Mapping and Natural Resource Evaluation”.
“The main objectives were to identify potential zones of favourable mineralisation and evaluate marine mineral resources,” Ashish Nath, superintendent geologist at GSI, told The Times of India.
The huge presence of marine resources was first identified off Mangaluru, Chennai, Mannar Basin, Andaman and Nicobar Islands and around Lakshadweep in early 2014. The amount of lime mud, phosphate-rich and calcareous sediments, hydrocarbons, metalliferous deposits and micronodules that geologists came across was a clear indication that deeper and more extensive exploration could lead to a larger treasure trove.
After three years of exploration, GSI has generated 181,025 square kilometres of high-resolution seabed morphological data and established the occurrence of more than 10,000 million tonnes of lime mud within the Exclusive Economic Zone of India. Exploration by GSI has confirmed the presence of phosphate sediment off Karwar, Mangaluru and Chennai coasts, gas hydrate in the Mannar Basin off the Tamil Nadu coast, ferro-manganese crust from the Andaman Sea and micro-manganese around Lakshwadweep Sea.
