Clay Minerals: Of the naturally occurring inorganic crystalline minerals found in the clay fraction (< 2µ) of soils, the most common are layer silicates (illite, montmorillonite, chlorite, vermiculite, kaolinite). Most of the physico-chemical and morphological properties of soil are influenced by these clay minerals.

A large number of silicates can be classified differently depending on whether we consider all tetrahedra of the structure, or only the silicon and aluminum tetrahedra. This problem is not treated consistently in the literature. In some cases aluminum tetrahedra are disregarded or other tetrahedra, like boron, are accepted.

The conventional geometric classification of the silicates is no longer sufficient to classify the ever-increasing number of determined ionic tetrahedral structures. More detail is desirable in the classification, and consequently, new classification criteria are necessary to provide a larger number of subdivisions.
