roweiten.

Brit.

/ˈrəʊʌɪt/, U.S.

/ˈroʊˌaɪt/

Origin: From a proper name, combined with an English element. Etymons: proper name Rowe , -ite suffix¹.

Etymology: < the name of George Rowe (1868–1947), Cornish-born U.S. mine official of Franklin, New Jersey, also a collector of local minerals and owner of one of very few specimens of roweite + -ite suffix¹.

Mineralogy.

A very rare mineral formed by the hydrothermal alteration of manganese ore and occurring as pinkish-brown nodular masses.Roweite is a basic borate of calcium and manganese (with traces of other metals), Ca₂Mn₂B₄O₇(OH)₆. Crystal system: orthorhombic.
