Brit.

/ˈmaɡnᵻsʌɪt/, U.S.

/ˈmæɡnəˌsaɪt/

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

Etymology: < German Magnesit ( D. L. G. Karsten Mineralogische Tabellen (1808) 48) < Magnesia magnesia n. + -it -ite suffix¹. French magnésite ( J. C. Delamétherie Théorie de la terre (ed. 2, 1797) II. 93) had earlier been used for magnesium minerals in general.

Mineralogy.

1. Magnesium carbonate, usually occurring as compact white granular masses and crystallizing in the trigonal system.
