Unformatted text preview: Kaolinite and Smectite. The ratio of Si:Al = 1:1 in Kaolinite and 2:1 in Smectite. 7. What is effective porosity? Porosity that is connected to outside (not isolated). 8. For sandstones, what does porosity depend mostly on? Grain size distribution, clay content, extent of compaction 9. What is a common method to measure porosity? Boyles law (or pressure chamber) method (give partial credit for: fluid summation, solvent extraction, mercury inj, picnometer, immersion) 10. What is the difference between “accuracy” and “precision”? Accuracy: measure of closeness to true value. Precision: Measure of variation between several measurements (without reference to true value)...
