WebClay minerals Group. This is a complex group of clay minerals with interlayering of different atomic structures, usually including some smectite layers. The layering can be irregular or regular; the regular ones include: corrensite, rectorite, tosudite and Aliettite. They need careful XRD and electron microscopy to properly characterise them. WebClay minerals have a sheet-like structure and are composed of mainly tetrahedrally arranged silicate and octahedrally arranged aluminate groups. Kaolinite is the principal mineral in kaolin clays. It is a 1:1 clay mineral – the basic unit is composed of a 2-dimensional (2D) layer of silicate groups tightly bonded to a 2D layer of aluminate ...
