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 ...
Thorium resources are the estimated mineral reserves of thorium on Earth. Thorium is a future potential source of low-carbon energy. [1] Thorium has been demonstrated to perform as a nuclear fuel in several reactor designs. [2] [3] It is present with a higher abundance than uranium in the crust of the earth. Thorium resources have not been ...
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.

Here, with Dunstan, thorianite [1] from Ceylon was described as a new mineral and he published papers on baddeleyite and zirkelite [2] from Ceylon [3] and carnotite from South Australia. [4] After this, he spent time in Matto Grosso , Brazil exploring for minerals, looking for gold at Timmins around Porcupine Lake, Ontario, and prospecting for ...
The mineral was discovered in Rakwana, Ceylon (now Sri Lanka). Baddeley was a superintendent of a railroad project in Rakwana. Baddeley was a superintendent of a railroad project in Rakwana. As recounted by J.J.H. Teall – director of the British Geological Survey in the early 1900s – baddeleyite was discovered consequent to the discovery of ...
Ekanite is an uncommon silicate mineral with chemical formula Ca 2 ThSi 8 O 20 or (Ca,Fe,Pb) 2 (Th,U)Si 8 O 20. It is a member of the steacyite group. It is among the few gemstones that are naturally radioactive. Most ekanite is mined in Sri Lanka, although deposits also occur in Russia and North America.
Muthurajawela is a marsh in Sri Lanka in the southern region of the Negombo lagoon, 30 km (19 mi) north of Colombo.The Muthurajawela Marshes are 3,068 ha (7,580 acres) in area and the country's largest saline coastal peat bog. [1]
