Ask me anything! A common example of a permeable rock is a limestone rock. Permeable rocks are defined rocks that have large enough interconnected spaces between particles to allow the movement of gas or liquid through them.
Permeability is as high as 1 md in unconsolidated sediment with 70% porosity and as low as 0.01 nanodarcy (nd) in argillite with 5% porosity. With few exceptions, permeability ranges over 3 factors of 10 at a given porosity and decreases progressively as porosity decreases.
