What is sandystone?

Sandstone is a sedimentary rock composed mainly of sand-sized minerals or rock grains, mostly quartz or feldspar. It is formed by the deposition of grains of sand on top of each other in layers and then being lithified or cemented together over time. Sandstones often have a distinctive color or texture, depending on the composition of the minerals they contain. They can range in color from white, beige, gray, and red to brown, tan, and even purple. Sandstone is used in a variety of construction applications, including building facades, retaining walls, and paving stones. It is also a popular building material for sculptures and monuments. Sandstone is abundant and found throughout the world, with notable examples including Petra in Jordan, the Grand Canyon in the United States, and Uluru in Australia.
