Gossan - Wikipedia
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 (which are
Gossan | Oxide Minerals, Iron Ore & Sulfide Minerals | Britannica
Gossan, rust-coloured oxide and hydroxide minerals of iron and manganese that cap an ore deposit. Gossans form by the oxidation of the sulfide minerals in an ore deposit and they thus may be used as clues to the existence of subsurface ore deposits, especially if …
Gossan - an overview | ScienceDirect Topics
Gossans are the signposts that point to what lies beneath the surface. Gossans are exceedingly ferruginous rock, which is the product of oxidation by weathering and leaching of sulfide mineralization.
Gossan - SpringerLink
Gossans are the normal end products of oxidation and leaching of iron-bearing sulfide deposits exposed to the surface environment by erosion. The principal oxidizing agent is atmospheric oxygen and the leaching is accomplished by descending ground waters of meteoric origin.
Gossan - Mining Fundamentals
Gossan is an intensely oxidized, weathered, or decomposed rock that is found on the upper and exposed part of an ore deposit or mineral vein. When gossan is exposed to water and air at the surface, the minerals tend to oxidize and liberate their contents.

2018年6月15日 · Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein (Figure 5). 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.
Gossan: Mineral information, data and localities. - mindat.org
An iron and manganese-bearing weathered product overlying a sulphide deposit. It is formed by the oxidation and leaching-out of sulphides and carbonates, with the loss of the sulphur and most metals, leaving hydrated iron oxides (limonite, hematite etc.) and manganese oxides, quartz and relatively insoluble minerals. Also spelled gozzan.

What Is Gossan | Gossan Features - Compare Nature
Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein. Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure. What is Gossan?
