摘要：

A new method is described, which gives quantitative information on levels and spatial distributions of porosity in the matrix of rock in the sub-mm- to cm-scale. Migration pathways can be identified and visualized. The method employs impregnation of dried rock samples by C-14-labelled methylmethacrylate (MMA), radiation polymerization, autoradiography and digital image processing. Infiltration and diffusion processes can be quenched by polymerization and the resulting profiles studied easily.
