Шаблон:Short description Шаблон:Infobox mineral Hureaulite is a manganese phosphate with the formula Шаблон:Chem2. It was discovered in 1825 and named in 1826 for the type locality, Les Hureaux, Saint-Sylvestre, Haute-Vienne, Limousin, France. It is sometimes written as huréaulite, but the IMA does not recommend this for English language text.[1]

A complete series exists from lithiophilite, Шаблон:Chem2 to triphylite, Шаблон:Chem2, including hureaulite, strengite, Шаблон:Chem2, stewartite, Шаблон:Chem2, and sicklerite, Шаблон:Chem2.[2]

Environment

Hureaulite is a secondary mineral occurring in granite pegmatites.[3] At the type locality it occurs in a zone of altered triphylite, Шаблон:Chem2, in pegmatite. Typically occurs very late in the sequence of formation of secondary phosphate minerals.[4] Associated at the type locality with vivianite, Шаблон:Chem2; rockbridgeite, Шаблон:Chem2; heterosite, Шаблон:Chem2 and cacoxenite, Шаблон:Chem2. It can be synthesised;[5] most natural hureaulites are Mn-rich compounds but extensive (Шаблон:Chem2) solution is known for synthetic material.[4]

Localities

The type locality is Les Hureaux, Saint-Sylvestre, Haute-Vienne, Limousin, France. Hureaulite is also found in a granite pegmatite known for its phosphates in the Aimorés pegmatite district, at the Cigana claim in Galiléia, Doce valley, Minas Gerais, Brazil, formerly known as the Jocão Mine.[6]
