Botryogen is a hydrous magnesium sulfate mineral with formula: MgFe 3+ (SO 4) 2 (OH)·7H 2 O. It is also known as quetenite. [3] It crystallizes in the monoclinic prismatic system and typically occurs as vitreous bright yellow to red botryoidal to reniform masses and radiating crystal prisms.

From the Greek βότρυς = "bunch of grapes" and γεννάν = "to bear", in allusion to the appearance of the original botryoidal and stalactitic masses found at Falun, Sweden. ⓘ Falun mine, Falun, Dalarna County, Sweden. Chemically similar to magnesiocopiapite, mountkeithite, and slavíkite.

Botryogen Comments: Bright orange botryogen on white calcite showing it's characteristic botryoidal "grape-like" morphology. Location: Cerro Pintados, Poza Almonte, Pampa del Tamarugal, Chile.

Botryogen is a hydrous magnesium sulfate mineral with formula: MgFe(SO4)2(OH)·7H2O. It is also known as quetenite. It crystallizes in the monoclinic prismatic system and typically occurs as vitreous bright yellow to red botryoidal to reniform masses and radiating crystal prisms.

Botryogen is a hydrous magnesium sulfate mineral with formula: MgFe 3+ (SO 4) 2 (OH)·7H 2 O. It is also known as quetenite. It was first described in 1828 for an occurrence in the Falu mine of Falun, Dalarna, Sweden. It was named for its grape-like appearance from Greek botrys for a bunch of grapes and genos to bear.

The meaning of BOTRYOGEN is a mineral MgFe(SO4)2(OH).7H2O consisting of a hydrous sulfate of iron and magnesium that is deep red or deep yellow and usually botryoid.
