/ˈbɑtriədʒən/,

/ˈbɑtriəˌdʒɛn/

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

Etymology: < German Botryogen (W. Haidinger 1828, in Ann. der Physik u. Chem. 12 491) < ancient Greek βοτρυο- , combining form (in e.g. βοτρυόδωρος grape-producing) of βότρυς bunch of grapes (see botryoid adj.; compare -o- connective) + -γενής (see -gen comb. form), so called in allusion to the botryoidal form of the mineral.

Mineralogy.

A magnesium-containing mineral that is an alteration product of pyrite typically occurring as reddish crystalline masses, often botryoidal or reniform. Cf. neoplase n., quetenite n.Botryogen is a basic hydrated sulphate of magnesium and ferric iron, MgFe³⁺(SO₄)₂(OH)·7H₂O. Crystal system: monoclinic.

1887 Amer. Naturalist 21 765 The botryogen of commerce was also analyzed, and found not to have the composition of the genuine mineral.

1910 Science 21 Oct. 559/1 The remaining sulphates described are copiapite,..botryogen and cyanotrichite.

1983 Mineral. Rec. 356 The zoning is not always the same but commonly copiapite occurs in the center and botryogen, var. quetnite, occurs as an outside rim.
