Figure 10.
The scatter plot shows diffusion values plotted against volume percent of features above 0.5 cubic millimetres for boom clay and eigenbilzen sands, eigenbilzen sands, and synthetic material. Data points include E S 1 B, B C 5, B C 2, B C 4, and B C 3 A, with diffusion ranging from about 2.0 into 10 power minus 10 to about 1.0 into 10 power minus 9. A linear trend line decreases from higher diffusion at lower volume percent to lower diffusion at higher volume percent, with equation y minus 4 into 10 power minus 8 x plus 9 into 10 power minus 10, and R squared 0.6603.Cross-plot of diffusion coefficient against the volume of features above 0.5 mm3 taken from Tables 6 and 7. Solid red circles show BC samples cut perpendicular to bedding while light red circles are for BC samples cut parallel to bedding. The dark blue diamond is for the Eigenbilzen Sands sample
