Porosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage. For most rocks, porosity varies from less than 1% to 40%. See more The porosities of the rocks measured vary from 2% to more than 30%. Much of this variation is due to lithology (rock type).
