In news– Hyderabad-based National Geophysical Research Institute has found large deposits of 15 rare earth elements(REE) in Andhra Pradesh’s Anantapur district recently.
Key updates-
- NGRI scientists conducted a survey looking for non-traditional rocks like syenites in Anantapur and successfully identified the host minerals.
- The major REE identified were allanite, ceriate, thorite, columbite, tantalite, apatite, zircon, monazite, pyrochlore euxenite and fluorite.
- Scientists also said that several alkaline syenite deposits earlier, which were reported by the Geological Survey of India were looked at afresh for REE-bearing minerals.
- Some of the potential hubs for these REE-bearing minerals include Dancherla, Peddavaduguru, Danduvaripalle, Reddypalle Chintalchervuand the Pulikonda complex in Anantapur and Chittoor districts.
- An estimated 5.9-million tonne reserve of lithium, a crucial mineral for the manufacturing of electric vehicles and solar panels, had been discovered in Reasi district by the Geological Survey of India (GSI).
- REE of the lanthanide series are critical components in many electronic devices like cellphones, televisions, computers, automobiles used daily and in various industrial applications.
- Lithium falls in the critical resource category, which was not earlier available in India and India was dependent for its 100 per cent import.
- The G3 (advanced) study of the GSI shows the presence of best quality lithium in abundant quantity in the foothills of Mata Vaishno Devi shrine at Salal village (Reasi).
