meioniten.

Brit.

/ˈmʌɪənʌɪt/, U.S.

/ˈmaɪəˌnaɪt/

Forms: 1800s meïonite, 1800s– meionite, 1800s– mionite.

Origin: A borrowing from French. Etymon: French meïonite.

Etymology: < French meïonite ( R. J. Haüy Traité de minéral. (1801) II. 586) < ancient Greek μείων lesser, less (see meio- comb. form) + French -ite -ite suffix¹.So called because the primitive form of its crystals is smaller than that of crystals of vesuvianite.

Mineralogy.

A tetragonal aluminosilicate mineral that is the calcium- and carbonate-rich endmember of the scapolite series and occurs as transparent, translucent, or pearly crystals of various colours. Cf. marialite n. 2.

1808 Jrnl. Nat. Philos. Nov. 191 Does the mineral mentioned by the name of meïonite in the Tableau méthodique of Mr. Haüy constitute a distinct species?

1808 Jrnl. Nat. Philos. Nov. 199 I have yet compared the meïonite with the feldspar only in respect to form.

1879 F. Rutley Study of Rocks x. 112 The species meionite and marialite are closely related to scapolite.

1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) XII. 51/2 The end members of the series are mirialite [sic]..and meionite, Ca₄Al₆Si₆O₂₄CO₃, whose compositions are suggestive of the plagioclase feldspars.
