Estimates of REV and its corresponding porosity as calculated using the linear regression models. Estimates are presented in original units.

Rock	Estimated REV (mm^3)	Porosity (%) estimate at estimated REV
Glass beads	6.2	35.3
Sand pack	6.1	35.0
Bentheimer	14.9	18.6
St. Bees	6.9	15.3
Mt. Gambier	19.1	42.3
