Only EE and EF types of particle association produce agglomerates which he terms "; The FF association is termed "aggre- gation" that refers not only to several FF multilayer par- ticles but also to the degree of unit-layer stacking in a single particle. The type of particle association actually produced will depend strongly on the physicochemistry of the suspension during sedimentation. Apparently all of the models described by van OljJien have not been found for natural sediments (Moon 1972). The models, however, do afford a means of reference for the study of fabric in natural clay-water systems. Prior to 1962, a few fabric studies of naturally consoli- dated clayey sediments had been published (Grim and others 1957; Kaarsberg 1959; White 1961; Meade 1961). In an excellent review of particle arrangement during com- paction (consolidation) of clayey sediment, Meade (1964)' contended that there was meager evidence showing that preferred and turbostratic fabrics are formed readily and generally during natural compaction (consolidation) al- though these fabrics could be reproduced in laboratory tests. Using X-ray diffraction techniques, Quigley and Thomp- son (1966) found that reorientation of clay platelets oc- curred during anisotropic consolidation of Leda marine cl
