  • A new study by the Indian Institute of Technology Kharagpur and Physical Research Laboratory explained how titanium-rich rocks formed on the Moon.
  • Lunar basalts have very high titanium dioxide (TiO), up to 18%, compared to less than 2% on Earth.
  • Scientists conducted high-pressure and high-temperature experiments to study conditions inside the Moon.
  • The study found a two-stage process of melting and mixing inside the Moon’s mantle.
  • A dense ilmenite-bearing layer (a titanium-rich mineral layer) sank and melted to form titanium-rich magma.
  • This magma later rose and formed titanium-rich volcanic rocks on the Moon’s surface.
