MINERALOGY: It is a mixture of various iron oxides may consist of varying proportions of goethite, magnetite, lepidocrocite, hematite, pitticita, jarosite, hisingerita, usually occurs in different forms, usually yellowish earthy masses, easily disintegrating, appears as training secondary alteration of iron ore, limonite also has organic origin: iron oxides in marine basins located precipitated by the action of certain bacteria, also formed by dissolution of carbonate and silicate rocks in subtropical and tropical climates.

MYTHOLOGY: The name of the Limonite was first used in 1832, is also usually true fossil material and can form stalactites. Synonymous with estilpnosiderita limonite is derived from a word meaning "splendor and brilliance".
