Forms: 1800s offrétite, 1800s– offretite.

Origin: A borrowing from French. Etymons: French offrétite, -ite.

Etymology: < French offrétite (F. Gonnard 1890, in Comptes rendus de l'Acad. des Sci. 111 1002) < the name of Albert J. J. Offret , French mineralogist (1857–1933) + -ite -ite suffix¹.

Mineralogy.

A mineral of the zeolite group which is a hydrated aluminosilicate of potassium and calcium and crystallizes in the trigonal system as colourless prisms.

1891 Jrnl. Chem. Soc. 60 407 Offrétite is a zeolite which occurs in very small quantity, associated with christianite and chabasite, in the basalt of Mount Simionse [sic], near Montbrison.

1970 Trans. Faraday Soc. 66 1616 Synthetic unfaulted offretite can provide a wide pore molecular sieve which can sorb molecules up to ∼7·1 Å in critical dimension... This zeolite appears to have possibilities as a versatile molecular sieve.

1992 W. A. Deer et al. Introd. Rock-forming Minerals (ed. 2) 523 The chabazite group [of zeolites] contains single (levyne, erionite, offretite) or double (chabazite, gmelinite, faujasite) six-fold rings of tetrahedra..which lie perpendicular to a triad or hexad axis.
