C chemistry performs a central role in the study of mineral colloids of soils, somewhat analagous to molecular structure in the study of organic compounds. Previous to derivation of structures, the determination of various reaction mechanisms in both fields is more or less of an empirical character. With a knowledge of structure, reaction mechanism (potassium release or methylation, for example,) is interpreted in terms of its seat within the unit cell or molecule, respectively, in the two fields. Crystal chemistry of the silicates of soils has the following chief aspects: (a) structural arrangement of ions as dictated by ionic size, (b) binding forces and mechanism, and (c) isomorphism. The present article is concerned with aspect (a), particularly the classification of natural silicates on the basis of their atomic structural groups and families. It is not concerned with presentation of detailed structures; references to literature are provided in which detailed structure may be obtained.
