The mineral pyrite (/ ˈ p aɪ r aɪ t / PY-ryte), [6] or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S 2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral .
The density of pyrite also means the fool's gold material thoroughly filled in tiny areas where the arthropod's body once lay in sediment − including internal body parts, scientists said. "These ...
Sulfide ores exposed to air and water undergo chemical reactions that create sulfuric acid that harms water quality and is toxic to fish and smaller aquatic organisms. The river is one of the most important rivers in Michigan as a part of a system that drains more than 4,000 square miles (10,000 km 2) of the Upper Peninsula and northern ...
They fish in it and they live off the tourists drawn to their turquoise waters, but now the Cook Islands wants to dig deeper, up to 6,000m (19,685 ft), where the nodules lie.

A creature that scuttled along the seafloor 450 million years ago has been preserved in a rare and striking fossil that formed in fool’s gold.
Previously it was discharged into the river, but it is now diverted to limit additional pollution of the river mouth area. The power plant's peak use of 3,000 cu ft/s (85 m 3 /s) of water exceeds the river's average flow of 741 cu ft/s (21.0 m 3 /s), so on some occasions, water is drawn upstream from Lake Erie into the plant.
