niocaliten.

Brit.

/ˌnʌɪəʊˈkalʌɪt/, U.S.

/ˌnaɪoʊˈkæˌlaɪt/

Origin: Formed within English, by derivation. Etymons: niobium n., calcium n., -ite suffix¹.

Etymology: < nio- (in niobium n.) + cal- (in calcium n.) + -ite suffix¹; apparently coined by E. H. Nickel (see quot. 1956).

Mineralogy.

A basic orthorhombic silicate and fluoride of niobium and calcium, (Ca,Nb)₄Si(O,OH,F)₉, which occurs as yellow crystals.

1958 Canad. Mineralogist 6 264 The niocalite occurs as randomly oriented, coarse, prismatic crystals up to one centimetre in length, and occasionally even longer, embedded in the calcite.

1966 Soviet Physics: Doklady 11 197/2 The Patterson projections show that niocalite does not have a screw axis.

1995 Mineral. Mag. 59 561 Niocalite and wöhlerite occur in calcite-silicate rocks of varying mineralogical composition.
