Pyrite is not an excellent jewelry stone because it easily tarnishes.)ADVERTISEMENT Pyrite as an Ore of Gold The most important use of pyrite is as an ore of gold. Gold and pyrite form under similar conditions and occur together in the same rocks. In some deposits small amounts of gold ...

nothing is a fool’s X by virtue of looking as though it has the easily observable properties of an X but really not having such easily observable properties.) No object could have the easily observable properties of being a plane figure with four equal sides and four equal angles and not...
Pyrite is an iron sulfide with the formula FeS2. It has a metallic luster and a pale yellow color (hence the name “fool’s gold”). It is relatively hard and commonly forms cubic crystals. It is the most common sulfide mineral and forms under a wide variety of conditions: in relatively...
The cradle chemistry of life: On the origin of natural products in a pyrite-pulled chemoautotrophic origin of life It is argued that life originated in an autocatalytic carbon dioxide fixation cycle. Specifically, an archaic version of the reductive citrate cycle is dis... Wachtershauser,G. - ...
It is also a common mineral in many types of sulfide ore and is present in most gold deposits. It grows or recrystallizes during the diagenesis of sediments, commonly through the action of bacteria: framboidal pyrite in sediments is commonly biogenic. Oxidation of pyrite provides an energy ...
Sulfur Dioxide Production:The thermal decomposition of pyrite generates sulfur dioxide, which is used in the paper industry for bleaching wood pulp. Geological Exploration:Pyrite serves as an indicator mineral for the presence of hydrothermal ore deposits, including those containing gold, copper, zinc,...
