Flint chemical formula
Apr 23, 2023 · Chert is a fine-grained sedimentary rock composed of quartz (SiO2) that is microcrystalline or cryptocrystalline quartz. It is usually organic rock but also occur inorganically as a chemical precipitate or a diagenetic replacement. It occurs as nodules, concretionary masses, and as layered deposits. Name origin: Term is used to refer generally ... The quartz is thought to have originated from skeletons of marine organisms, and in fact flint sometimes contains fossilized remains. Flint nodules were often dug out of chalk deposits—an old (5000 years) flint mine can be visited at Grimes Graves, Lynford, Thetford, Norfolk, UK—52 28 34.00 N 0 40 30.60 E.
