Most notable of the gemstones to form in this system are diamonds, garnets, fluorite, pyrite, and spinel. Pyrite occurs in brassy crystals or sometimes as nodules in Devonian and Pennsylvanian shales. This newly produced mineral then accumulates at the bottom of the ocean, creating abundant pyrite mineral surfaces. Summary Pyrite formation results from the reaction of H;S, from bacterial sulfate reduction, with reactive detrital iron minerals. The topography of Virginia was formed through a series of continental collisions that created vast mountain ranges in Virginia. A common form is the pyritohedron , a 12-sided. Iron-bearing minerals likely to occur in coal include siderite, hematite, marcasite, and goethite (Elliot, 1981). Some economic chalcopyrite deposits form as hydrothermal fluids dissolve copper from igneous rocks and then precipitate it in surrounding contact-metamorphosed sedimentary rocks.
