radioliten.

Brit.

/ˈreɪdɪə(ʊ)lʌɪt/, U.S.

/ˈreɪdiəˌlaɪt/

Origin: Formed within English, by compounding. Etymons: radius n., -o- connective, -lite comb. form¹.

Etymology: < radius n. + -o- connective + -lite comb. form¹. In sense 1 after either French radiolite or scientific Latin Radiolites, genus name (both in Lamarck Système des animaux sans vertèbres (1801) 130). In sense 2 after German Radiolith (J. Esmark, cited in Jrnl. f. Chemie u. Physik (1828) 52 361); compare Swedish radiolit (1846).

Now rare.

1. Palaeontology. A rudist bivalve mollusc of the Cretaceous genus Radiolites or family Radiolitidae; = radiolitid n. N.E.D. (1903) gives another sense, for a kind of cephalopod, citing G. B. Sowerby Man. Conchol. (1839) 91, but this arises from a misreading of Radiolites for Radiolata.

1859 D. Page Handbk. Geol. Terms 310 The Radiolite has an inversely conical under-valve, with a deep straight cavity.

1878 Jrnl. Anthropol. Inst. 7 358 Below the nummulites, hippurites, and radiolites (Rudisten-Kalk), lies on both sides of the valley, with a sharp dip, a band of limestone..which polishes like marble.

1967 Philos. Trans. (Royal Soc.) B. 252 94 Chubb..draws attention to three specimens of the gregarious radiolite Thyrastylon adherens.

2. Mineralogy. A variety of natrolite occurring in masses with a radiated structure. Chiefly historical.

1868 J. D. Dana Syst. Mineral. (ed. 5) 427 The radiolite is in radiated masses, and compact fibrous nodules, of a grayish color.

1911 Encycl. Brit. XIX. 273/2 The mineral also often occurs in compact fibrous aggregates, the fibres having a divergent or radial arrangement (hence the name radiolite for one variety).

1993 A. M. Clark Hey's Mineral Index (ed. 3) 583/2 Radiolite,..a provisional name for the material later recognised as natrolite (of Klaproth). Named from its radiating habit.
