Porosity is a measure of void spaces in the rock. This void fraction can be either between particles or inside cavities or cracks of the soil or rock. Porosity defined as a unit fraction between 0 and 1 or as a percentage between 0 and 100%. For most rocks, porosity is normally varying from less than 1 to 40%.
