Web• Laminated – thin layers of clay between sand units. • Structural – clay particles constitute part of the rock matrix, and are distributed within it. An example of this is coprolites. • Dispersed – clay in the open spaces between the grains of the clastic matrix. These are depicted schematically in Fig. 20.1. WebPorosity is the pore space in soil between mineral particles (and solid organic matter) filled with either air or water. The pore space both contains and controls most of the functions of soil. It is not just the total amount of pore space that is important, but the size distribution of the pores, and the continuity between them which determines function and behaviour of …
