Record 3 2012-04-25

English

Subject field(s)
  • Mineralogy
  • Radioactive Ores (Mining)
Universal entry(ies)
(Th,U)SiO4
formula, see observation
(Th,Fe,Y,P,Ca)SiO4
formula, see observation
DEF

A radioactive mineral consisting of thorium silicate.

CONT

The radioactivity of thorite often brings it to a state of metamiction, in which its crystal structure becomes unstable thereby causing the crystal edges to become smooth and rounded. When this happens, the thorite may gain hydroxyl(OH) molecules in place of the silica(SiO4) molecules and transform into a different mineral, thorogummite.

OBS

Thorite is currently an important ore of uranium. A variety of thorite often called "uranothorite" is particularly rich in uranium... Other varieties of thorite include "orangite, "an orange variety; "calciothorite" an impure variety with trace amounts of calcium and "freyalite" actually a discredited variety containing cerium([which] turned out to be an altered form of the mineral melanocerite).
