rock in this sense includes soils, ceramic clays, clay shales, mudstones, glacial these are all characterized by the presence of one or more clay minerals,
the surface properties of clay minerals are a function of the chemical composition and nature of the surface atoms, extent and type of defect sites, layer charge,
most of these are thermally stable and hold as pillars to allow a porous structure in the interlayer space. the resulting complexes, often called pillared clays, exhibit

the types and characteristics of clay minerals depends on their origin of occurrences. commonly clay minerals are formed over a long period of time by gradual
surface charges play a major role in determining the interactions of contaminants with soils. the most important sources of soil charges are clay mineral colloids,
clay minerals are layer silicates that are formed usually as products of chemical sodium smectite will retain its water-tight properties so long as the slurry is

one of the basic characteristics of heavy soils is their capacity to change their volume, which is induced by swelling and shrinking processes. these processes
the small size of the particles and their unique crystal structures give clay materials special properties, including cation exchange capabilities, plastic behavior when wet, catalytic abilities, swelling behavior, and low permeabilities.
using a global soil map, a global dataset of soil clay-size mineral clay lends the properties of viscosity and plasticity to wet soils and causes
