pitticiten.

Brit.

/ˈpɪtᵻsʌɪt/, U.S.

/ˈpɪdəˌsaɪt/

Forms: 1800s pittizite, 1800s– pitticite.

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

Etymology: < German Pittizit ( J. F. L. Hausmann Handbuch der Mineralogie (1813) I. 285), apparently < ancient Greek πίττα pitch (see pissasphalt n.) + German -it -ite suffix¹, with insertion of -iz- probably after Cubizit cubicite n., the mineral apparently being so called on account of the pitch-black colour of its dark variety.In form pittizite after the German form.

Mineralogy.

A secondary iron mineral of variable composition based on amorphous hydrous ferric arsenate, occurring as pale grey, yellowish, or reddish to dark brown crusts or rounded masses, often with a vitreous or greasy lustre; any of the varieties of this.
