Basics of Clay Minerals and Their Characteristic Properties

Clay minerals most commonly form by prolonged chemical weathering of silicate-bearing rocks. They can also form locally from hydrothermal activity. Chemical weathering takes place largely by acid hydrolysis due to low concentrations of carbonic acid, dissolved in rainwater or released by plant roots. The acid breaks bonds between aluminium and oxygen, releasing other metal ions and silica (… Webbond clay: [noun] a plastic ceramic clay that gives strength to dry but unfired ware. error listing directory root winscp
