rankiniten.

Brit.

/ˈraŋkᵻnʌɪt/, U.S.

/ˈræŋkəˌnaɪt/

Origin: From a proper name, combined with an English element. Etymons: proper name Rankin , -ite suffix¹.

Etymology: < the name of G. A. Rankin (1884–1963), U.S. physical chemist + -ite suffix¹ (see quot. 1942).

Mineralogy.

A colourless or white mineral occurring as prisms or, more commonly, in massive form, esp. as a constituent of skarns and in blast-furnace slag.Rankinite is a silicate of calcium, Ca₃Si₂O₇, that is dimorphous with kilchoanite. Crystal system: monoclinic.

1942 C. E. Tilley in Mineral. Mag. 26 194 For the new mineral the name rankinite is now proposed in honour of Mr. G. A. Rankin, who has contributed so much to our knowledge of the binary and ternary systems in which it was first discovered as a constituent phase.

1966 W. A. Deer et al. Introd. Rock-forming Minerals i. 77 Rankinite occurs at contacts between limestone and basic igneous rocks, as at Scawt Hill, Northern Ireland, and Ardnamurchan.

1974 Mineral. Abstr. 25 322/1 Rankinite occurs in the metasomatic formations of the Anakitsk trap massif, in the Lower Tunguska area [of the U.S.S.R.], where it is associated with other high-temperature phases.

2006 Jrnl. Non-crystalline Solids 352 182/1 At 1082 K the observed calcium silicate is hatrurite (Ca₃SiO₅), changing with increasing temperature to larnite (Ca₂SiO₄), then to rankinite (Ca₃Si₂O₇), and eventually to wollastonite (CaSiO₃).
