This specimen of pinkish garnet crystals comes from the huge open-pit Asbestos quarry in Quebec, Canada, known in English as the "Jeffrey Mine". It was mined for asbestos. It's one of the largest man-made "holes" on Earth. This locality has produced the world-famous garnets and vesuvianite and many other beautiful mineral species.
Limonite is a general term for a mixture of fine-grained iron oxides, generally dominated by goethite, but also possibly containing hematite, lepidochrocite and other minerals. It forms from the weathering of other iron minerals, and may …
Limonite: Limonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)·nH 2 O). It was originally considered one of a series of such oxides. The name limonite properly should be restricted to impure hydrated iron oxide (with variable water content) that is colloidal, or amorphous, in character.
What is the chemistry of limonite? The chemical formula of Limonite is FeO(OH)·nH₂O. In other words, the oxygen and hydrogen of the air and moisture have replaced the atoms of sulfur in the outer layer. The limonite remains bonded to the pyrite at their interface. It's rather like a skin has formed over the pyrite.

Limonite: The mineral Limonite information and pictures. 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.
In addition, it can be formed from weathering processes on other minerals rich in iron. When found in a deposit, limonite is an amorphous solid, appearing in shades of yellow or brown, with a moderate hardness level of 4 - 5.5 on the Mohs scale(1). When mined, it can be broken into shards, or ground to a powder for use. Yellow ochre is non-toxic.

Limonite was mined for its ancillary gold content. The oxidation of sulfide deposits which contained gold, often resulted in the concentration of gold in the iron oxide and quartz of the gossans. The gold of the primary veins was concentrated into the limonites of the deeply weathered rocks.
The metal is formed when minerals are eroded from their original spot and then carried by water somewhere else (this is called stream bed mining or alluvial mining). …
