. Collected reprints / Atlantic Oceanographic and Meteorological Laboratories [and] Pacific Oceanographic Laboratories. Oceanography Richard H. Bennett, William R. Bryant, and George H. Keller 15 Kirkpatrick and Rennie (1972) reported on the fabric of laboratory consolidated kaolin as observed by electron microscopy. Although the samples were air dried, the fabric was assumed to be representative of the wet samples. With these reservations in mind, the results indicated that kaolins consolidated under isotropic conditions had an isotropic structure with the clay particles oriented at random. Kaolin samples consolidated anisotropically were found to have a strongly oriented structure with the clay particles oriented at right angles to the direction of the principal stress. The increasing observational evidence suggests that single clay particle fabric of sediment is not wholly tenable and that sediment fabric is more accurately represented by domain, aggregate and linking chain particle arrangements. Models of clay fabric are beginning to emerge with these more recent observations and concepts in mind (Moon 1972; Yong and Sheeran 1973; Collins and McGown 1974). A model of clay particle arrangement for unconsolidated versus consolidated sediment representing flocculated and dis- persed conditions has been proposed by Moon (1972). Con- ceptually the model accounts for the basic domain particle interaction during consolidation with particle alignment of flocculated fresh clay. domains toward preferred orientation (fig. 23). As consoli- dation proceeds, more particles are incorporated into each domain. Domains are of the "book" and "stepped face-to- face" type. Fabric unit interaction and classification were recently dis- cussed for the purpose of predicting response soil behavior and for the development of fabric models which more closely approach a physical description of real sedimentary mate- rial (Yong and Sheeran 1973).
