Brit.

/ˈrɪktərʌɪt/, U.S.

/ˈrɪktəˌraɪt/

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

Etymology: < the name of H. Theodor Richter (1824–98), German metallurgical chemist + -ite suffix¹, after German Richterit (A. Breithaupt 1865, in Berg- u. Hüttenmännische Zeitung 24 364).

Mineralogy.

A ferromagnesian mineral of the amphibole group, occurring as elongated brown, yellow, red, or green crystals.Richterite is a silicate of sodium, calcium, magnesium, and (usually) iron( ii), Na₂Ca(Mg,Fe)₅Si₈O₂₂(OH)₂; it was formerly thought to contain manganese. Crystal system: monoclinic.
