Clay is a type of fine-grained natural soil material containing clay minerals [ 1 ] (hydrous aluminium phyllosilicates, e.g. kaolinite, Al 2 Si 2 O 5 (OH) 4). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities ...
Clay cannot be resolved by optical microscopes as its particles are 0.002 mm (7.9 × 10 −5 in) or less in diameter and a thickness of only 10 angstroms (10 −10 m). [16] [17] In medium-textured soils, clay is often washed downward through the soil profile (a process called eluviation) and accumulates in the subsoil (a process called ...

Claypan is a dense, compact, slowly permeable layer in the subsoil. [1] It has a much higher clay content than the overlying material, from which it is separated by a sharply defined boundary. The dense structure restricts root growth and water infiltration. Therefore, a perched water table might form on top of the claypan. [2]
