Minerals silicates
Web1 jan. 2016 · Hydrous clay minerals are layer‐lattice silicates that comprise tetrahedrally (Si, Al, Fe 3+) and octahedrally (Al, Fe 3+, Fe 2+, Mg) coordinated cations that form either sheets or chains (Brown, 1961).The basic structural units in layer silicates are silica sheets and brucite (MgOH 2) or gibbsite (AlOH 3) sheets.Silica sheets consist of SiO 4 2− …
