GEOMETRY AND TOPOLOGY OF POROUS MATERIALS.

Porous materials are heterogeneous two-phase systems. One phase is solid and one phase fluid or empty. Both phases must be at least part macroscopically continuous. The skeletization procedure of Lin and Cohen elucidates simply but precisely the principal topological and geometric features of porous materials, providing rigorous definition of the familiar concepts of chambers, channels, and throats in the pore space. The power and utility of their method is well illustrated through an analysis of the morphologies of sedimentary rocks.
