**Davidite** is a [rare earth](/source/Rare_earth_mineral) [oxide](/source/Oxide) mineral with chemical [end members](/source/End_member) [Lanthanum](/source/Lanthanum) (La) and [Cerium](/source/Cerium) (Ce). It exists in two forms:

- Davidite-(La) (La,Ce,Ca)(Y,U)(Ti,Fe3+ ) 20O 38 discovered at [Radium Hill](/source/Radium_Hill) mine, [South Australia](/source/South_Australia) in 1906 and named by [Douglas Mawson](/source/Douglas_Mawson) for Australian geologist [Tannatt William Edgeworth David](/source/Edgeworth_David) (1858-1934).[7][8]

- Davidite-(Ce) (Ce,La)(Y,U)(Ti,Fe3+ ) 20O 38 first described in 1960 from Vemork, [Iveland](/source/Iveland), [Norway](/source/Norway).
