FAQ
Frequently Asked Questions
Yes, like many radioactive minerals, raw thorite specimens should be handled with care, using gloves and avoiding inhalation of dust, due to their radioactivity and potential to release radon gas.
It is found in accessory amounts in granite pegmatites and certain types of veins. Detrital grains can also be found in some placer deposits (sands). Notable locations include Norway, Madagascar, and the United States.
Thorite is thorium silicate (ThSiO₄). Thorianite is thorium oxide (ThO₂). They are two distinct mineral species, both ores of thorium.
Yes, due to its radioactive thorium content, thorite can be used in uranium-thorium dating methods to determine the age of geological formations where it crystallized.
