Thorianite is a rare thorium oxide mineral, ThO 2. [5] It was originally described by Ananda Coomaraswamy in 1904 as uraninite, [6] but recognized as a new species by Wyndham R. Dunstan. [7] It was so named by Dunstan on account of its high percentage of thorium; it also contains the oxides of uranium, lanthanum, cerium, praseodymium and neodymium.
Thorium occurs in several minerals including thorite (ThSiO 4), thorianite (ThO 2 + UO 2) and monazite. Thorianite is a rare mineral and may contain up to about 12% thorium oxide. Monazite contains 2.5% thorium, allanite has 0.1 to 2% thorium and zircon can have up to 0.4% thorium. [2] Thorium-containing minerals occur on all continents.
