Porosity ranges from 20% to 70% for most unconsolidated materials (i.e. for soils). However, it is not common to have a large range of porosities in one situation. As noted above, porosity is the primary property related to resistivity, hence the difficulty in distinguishing between sand and gravel with the same porosity.

Jan 03, 2021· Sandstone can have up to 30% porosity, while limestone can have up to 20% porosity. The high level of porosity means that the molecules inside are less tightly packed, which makes these types of stones easier to work with and shape. It also means that sandstone and limestone are more vulnerable to water damage and staining.

Most sandstones feel gritty, and some are easily crushed (friable) and break up to form sand. Sandstones have pore spaces between each grain of sand; this property, called porosity, makes them good reservoirs for oil and natural gas. Sandstones are very resistant to erosion and form bluffs, cliffs, ridges, rapids, arches, and waterfalls.
