WebFeb 18, 2024 · Primary porosity is the result of processes which occurred during deposition, while secondary porosity happens due to processes which occur after rock is formed. For example, deposits of a more soluble mineral inside a hard mineral may be gradually dissolved over time, making the rock more porous. Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam). There are many ways to test porosity in a substance or part, such as industrial CT scanning.
