Clay Mineral - an overview ScienceDirect Topics

WebMinerals form under an enormous range of geologic conditions. There are probably more ways to form minerals than there are types of minerals themselves. Minerals can form from volcanic gases, sediment formation, oxidation, crystallization from magma, or deposition from a saline fluid, to list a few. Some of these methods of mineral formation ... WebHydrolysis: This reaction is responsible for the formation of clays, the most important mineral in soils. A typical hydrolytic reaction occurs when orthoclase feldspar reacts with slightly acidic water to form clay minerals, potassium ions, and silica in solution: 2KAlSi 3 O 8 + 2H + + 9H 2 O -> Al2Si 2 O 5 (OH) 4 + 2K + + 4H 4 SiO 4 open source bacnet for linux
