neptuniten.

Brit.

/ˈnɛptjuːnʌɪt/,

/ˈnɛptʃuːnʌɪt/, U.S.

/ˈnɛpˌt(j)uˌnaɪt/

Origin: Formed within English, by derivation; modelled on a Swedish lexical item. Etymons: Neptune n., -ite suffix¹.

Etymology: < Neptune n. + -ite suffix¹, after Swedish neptunit (G. Flink (at the suggestion of N. O. Holst) 1893, in Geol. Föreningens i Stockholm Förhandl. 15 196), so called because of its occurrence with aegirine (see aegirite n.), Ægir being the name of the sea-god in Scandinavian mythology.

Mineralogy.

A monoclinic silicate of sodium, potassium, lithium, ferrous iron, manganese, and titanium, usually occurring as black prismatic crystals.

1895 Mineral. Mag. 11 100 Owing to the close similarity of the crystal angles to those of sphene, neptunite is placed in the titanite group.

1926 Mineral. Abstr. 3 102 Neptunite has been found at eight spots in the Kola peninsula.

1950 Mineral. Mag. 29 27 The main point of interest in the new material is the presence here and there of the rare mineral neptunite in the syenite, a mineral previously unknown in the British Isles.

1966 Doklady Earth Sci. 166 121/2 The pyroxenic structure of neptunite is typically apparent from the endless zigzag baroque columns, in which Ti and Mn octahedra connected by common edges alternate in pairs.

1990 C. Pellant Rocks, Minerals & Fossils 87 Neptunite...Formation: in undersaturated plutonic rocks such as nepheline syenites, as an accessory mineral.
