  • Misspelling as 'thoride' (which is a chemical compound, e.g., ThO₂ is thorium oxide/thoride).
  • Incorrect pronunciation placing stress on the second syllable (/θəˈraɪt/).

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.

Thorite is usually technical/scientific in register.

Thorite: in British English it is pronounced /ˈθɔːraɪt/, and in American English it is pronounced /ˈθɔraɪt/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Think of THOR (the Norse god associated with strength) + ITE (a common ending for minerals/rocks). A 'strong' (radioactive) mineral named after the element thorium, which itself is named after Thor.

Conceptual Metaphor

A CONTAINER OF VALUE (for the element thorium). A TIME CAPSULE (due to its use in radiometric dating).
