Gravel and … WebThe crystalline rock such as granite has a very low porosity (<1%) since the only pore spaces are the tiny, long, thin cracks between the individual mineral grains. Sandstones, typically, have much higher porosities (10–35%) because the individual sand or mineral grains don’t fit together closely, allowing larger pore spaces. 2 More answers below
