Uranium and Thorium Distribution NeoStencil

Thorium. Natural thorium is usually almost pure 232Th, which is the longest-lived and most stable isotope of thorium; Thorium is more abundant in nature than uranium. Thorium only occurs as a minor constituent of most minerals and was for this reason previously thought to be rare.

The Future of Thorium as Nuclear Fuel Gold Geologist

Thorium is a silvery-white metal that was discovered in 1828 in the mineral monazite, a rare earth-thorium phosphate. It is one of the heaviest elements at number 90 on the periodic table, two spots below uranium. Thorium is a relatively common element at 15 ppm in the Earth's crust, which is three times the abundance of uranium.

The thorium content of minerals contained in these placers is considerably greater than the uranium content; therefore the deposits are classified primarily as thorium-bearing placers. In India monazite is found in the coastal tracts of Cuttak and Ganjam districts of Orissa where the thickness of the placer is about 30 cm with a monazite content of 2.5 percent.

Nature, Sources, Resources, and Production of Thorium

The most common thorium mineral is monazite. In uranium ore deposits, thorium is concentrated in thorite and thorianite. In magmatic carbonate-enriched rocks (carbonatites), thorium is associated with rare earth elements (REE) in bastnaesite. However, the most important reserves of thorium occur in placer deposits, which contain monazite.
