 (smĭth′sə-nīt′)
n.
A mineral, ZnCO3, sometimes used as a source of zinc.

[After James Smithson.]

smithsonite

(ˈsmɪθsəˌnaɪt)
n
(Minerals) a white mineral consisting of zinc carbonate in hexagonal crystalline form: occurs chiefly in dry limestone regions and is a source of zinc. Formula: ZnCO3. Also called (US): calamine
[C19: named after James Smithson]

smith•son•ite

(ˈsmɪθ səˌnaɪt)

n.
a mineral, zinc carbonate, ZnCO3, found in crusts and masses: an ore of zinc.
[1825–35; after J. Smithson, who distinguished it from calamine; see -ite1]
