Large deposits of 15 rare earth elements found in Andhra Pradesh

Current Affairs

  • Hyderabad-based National Geophysical Research Institute has found large deposits of 15 Rare Earth Elements (REE) in Andhra Pradesh’s Anantapur district.
  • REEs (aka rare earth oxides) are a group of 17 silvery-white soft heavy metals that occur together in periodic table.
  • NGRI scientists conducted a survey looking for non-traditional rocks like syenites and successfully identified the host minerals.
  • The major REE identified included ceriate, allanite, thorite, tantalite, columbite, apatite, monazite, zircon, pyrochlore, euxenite, and fluorite.
  • A subfield of geology known as “metallogeny” studies the genetic connection between a region’s geological past and its mineral deposits.
  • In the Anantapur district, west and southwest of the Paleoproterozoic Cuddapah basin, are the alkaline complexes.
  • Earlier this year, the Geological Survey of India (GSI) had found an estimated 5.9-million tonne lithium reserve in the Reasi district of Jammu and Kashmir for the first time in the country.
  • Lithium is an essential mineral for the production of solar panels and electric vehicles .
  • REEs are used in high end technology, defence applications, electronic devices like cell-phones, computers, electric vehicle etc. because of their luminescent and catalytic properties.
