How did the sedimentary pyrite form?
Pyrite belt is not stable in oxidation, decomposition of ferric hydroxide form such as goethite, lepidocrocite, after dehydration, which can form a stable limonite, and often in pyrite into illusion.
Pyrite is one of the most widely distributed of sulfide minerals in the earth, is the main component of two iron sulfide (FeS2), pure pyrite containing 46.67% iron and 53.33% sulfur industry called pyrite. Often crystalline or massive aggregates of cubes, five angles, twelve faces, found in a variety of ore and rock origin. The pyrite in the coal seam tends to be a nodule. Because of its pale brass color and bright metallic luster, it is often mistaken for gold, so it is also called "fool's gold"".
This effect is often part of the outcrop in metal oxide deposit with the formation of limonite or goethite, lepidocrocite covered in ore body, so called gossan. Jarosite can be formed under the condition of strong acidity of oxidation zone, and its distribution is only inferior to limonite.
