datoliten.

Brit.

/ˈdatəlʌɪt/, U.S.

/ˈdædəˌlaɪt/

Forms: 1800s– datholite, 1800s– datolite.

Origin: A borrowing from German. Etymon: German Datolith.

Etymology: < German Datolith (J. Esmark, reported in Neues allgemeines Jrnl. der Chem. (1806) 16 108) (formerly also written Datholit , Datholith ); < dat- (in ancient Greek δατεῖσθαι to divide; < an ablaut variant (zero grade) of the same base as δῆμος deme n.²) + -lith -lith comb. form), with remodelling of the ending after -lite comb. form¹.Forms with -th- in the first element (both in German and English) are probably hypercorrect spellings (there is no difference in pronunciation between t and th in German).

Mineralogy.

A boron-containing mineral typically occurring as colourless glassy crystals or fine-grained masses, esp. as a secondary mineral on basic igneous rocks.Datolite is a basic calcium borosilicate, CaBSiO₄(OH). Crystal system: monoclinic.

1807 Retrospect of Discov. 2 364 Mr. Esmark has discovered at Arandahl, in Norway, a new mineral, to which he gives the name of datolite.

1868 J. D. Dana Syst. Mineral. (ed. 5) 382 Datolite is found in trappean rocks.

1898 Amer. Naturalist 32 816 The crystals assume three types of habit, one of which closely simulates that of datolite from Bergen Hill.
