Sandstone is a sedimentary rock composed of sand-size grains of mineral, rock, or organic material. It also contains a cementing material that binds the sand grains together and may contain a matrix of silt- or clay-size particles that occupy the spaces between the sand grains. When a depositional environment has sand in it and water or air moves the sand grains around, those grains can build up into piles of sediment. When the sediment piles reach a height where they are unstable - called the angle of repose - the grains will avalanche down the side of the pile and make a thin depositional layer of the grains that moved.Sedimentary structures are visible textures or arrangements of sediments within a rock. Geologists use these structures to interpret the processes that made the rock and the environment in which it formed.
