Limonite l a m n a t is an iron ore consisting of a mixture of hydrated ironIII oxidehydroxides in varying composition. The generic formula is frequently written as FeOOH 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
In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements.

Limonite is a matrix base of many other minerals, and the term gossan is used as a reference to Limonite when it is used as a a matrix for another mineral or has formed an undesirable staining on top of it. Limonite is extremely common and forms the coloring matter in many soils.
Many chemically formed ore shoots yield good ore deposits. During vein formation, hot silica quartzrich, hydrothermal acidic fluids react with rocks with favorable chemistry particularly rocks with calcium carbonate limestone, dolomite. Thus, following a vein that cuts through limestone could lead prospectors to find skarns, replacement deposits, etc for gold and other valuable minerals.
Geologic Occurrence. Limonite usually occurs as a secondary material, formed from the weathering of hematite, magnetite, pyrite, and other ironbearing is often stalactitic, reniform, botryoidal, or mammillary in habit, rather than also occurs as pseudomorphs and coatings on the walls of fractures and cavities.
