Limonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxidehydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and
Abstract. The Bou Jaber BaFPbZn deposit is loed at the edge of the Bou Jaber Triassic salt diapir in the Tunisia Salt Diapir Province. The ores are unconformity and faultcontrolled and occur as subvertical columnshaped bodies developed in dissolutioncollapse breccias and in cavities within the Late Aptian platform carbonate rocks, which are covered unconformably by impermeable shales
