Sandstone is a clastic sedimentary rock composed primarily of sand-size grains.The sand-size grains of sandstone can be composed of minerals such as quartz or feldspar, rock or organic material. Rock formations which are mainly composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum resevoirs. Fine aquifers, such as sandstones, are better able to filter pollutants from the surface than rocks with cracks, such as limestone or other cracked rocks due to seismic activity.
