römeriten.

Brit.

/ˈrəːmərʌɪt/, U.S.

/ˈroʊməraɪt/

Forms: 1800s– roemerite, 1900s– römerite.

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

Etymology: < the name of Friedrich Adolph Römer (1809–69), German geologist + -ite suffix¹, after German Römerit (J. Grailich 1858, in Sitzungsber. der Kaiserlichen Akad. der Wissensch. in Wien 28 272).

Mineralogy.

An iron-containing mineral which occurs as rust-brown to yellow crystals, typically as an oxidation product of pyrite.Römerite is a hydrated sulphate of iron( ii) and iron( iii), Fe²⁺Fe₂³⁺(SO₄)₄·14H₂0. Crystal system: triclinic.
