Gossan (eiserner hut or eisenhut ) is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein. In the classic gossan or iron cap all that remains is iron oxides and quartz often in the form of boxworks, quartz lined cavities retaining the shape of the dissolved ore minerals.In other cases quartz and iron oxides, limonite, goethite .

Goethite - Wikipedia

Goethite - Wikipedia

Goethite often forms through the weathering of other iron-rich minerals, and thus is a common component of soils, concentrated in laterite soils. nanoparticulate authigenic goethite is a common diagenetic iron oxyhydroxide in both marine and lake sediments. The formation of goethite is marked by the oxidation state change of Fe 2+ (ferrous) to Fe 3+ (ferric), which allows for goethite to exist .
