Sandstone is a sedimentary rock formed of sand grains typically (1/16 to 2 mm in diameter) that are cemented together. Sand-sized particles are generally composed of other rocks and minerals, such as feldspar, quartz, rock fragments, and clay. The material cementing the sand grains can be silica, calcium carbonate, or iron oxides. Depending on the composition of the sands and cement, the hardness of sandstone can vary. Sandstone can be a variety of colours, but are typically grey, brown, yellow, and sometimes red, green, or white.
