sandstones
Gritty sedimentary formations
Sandstones is the plural of sandstone, a sedite sedimentary rock composed of sand-sized grains, typically quartz, cemented together.
Different sandstones vary in color, hardness, and composition depending on their mineral content and formation conditions: The canyon walls revealed layers of red and tan sandstones.
Sandstone is widely used in construction and paving.
