Quartz is by far the most common iron ore gangue mineral overall, whereas clays (kaolinite and gibbsite) predominate in weathered supergene altered and near-surface exposures of ore deposits, while minnesotaite and stilpnomelane are the most common silicate minerals in unweathered iron formation deposits. There are many other major to minor gangue minerals associated with iron ore deposits

Limonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides 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.

iron ores were developed in quartzose, ferruginous sedimentary rocks by a concentrating action of magmatic solutions during a period of metamorphism (2, p. 364). Also Zuloaga believed that magmatic solutions concentrated the iron, but he did not stress the metamorphic aspects of the ore (22, p. 332).

The ore is a weathered ilmenite deposit in which iron oxide has been partially removed by time, and therefore a portion of ilmenite has naturally altered to pseudorutile (Fe 2 Ti 3 O 9). In this phenomenon, pseudorutile is eventually altered to TiO 2 through the leaching removal of iron as hematite.
