Davidite is a rare earth oxide mineral with chemical end members La and Ce. It exists in two forms:

  • Davidite-(La) (La,Ce,Ca)(Y,U)(Ti,Fe3+)20O38 discovered at Radium Hill mine, South Australia in 1906 and named by Douglas Mawson for Australian geologist Tannatt William Edgeworth David (1858-1934).
  • Davidite-(Ce) (Ce,La)(Y,U)(Ti,Fe3+)20O38 first described in 1960 from Vemork, Iveland, Norway.
