roscheriten.

Brit.

/ˈrɒʃərʌɪt/, U.S.

/ˈrɑʃəˌraɪt/

Origin: From a proper name, combined with an English element; modelled on a German lexical item. Etymons: proper name Roscher , -ite suffix¹.

Etymology: < the name of Woldemar Roscher (1866–1934), German pharmacist and mineral collector + -ite suffix¹, after German Roscherit (F. Slavík 1914, in Bull. internat. de l'Acad. Tchèque des Sciences, Prague 19 109).

Mineralogy.

A phosphate mineral occurring chiefly as reddish or brownish crystals in cavities in granite and pegmatite. Roscherite is a hydrated phosphate and hydroxide of beryllium, calcium, iron, and manganese, Ca(Mn,Fe)₂Be₃(PO₄)₃(OH)₃·2H₂O. Crystal system: monoclinic. The presence of beryllium was not discovered until 1958, the mineral previously having been believed to contain aluminium.
