Siltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate. Sedimentary structures include all kinds of features in sediments and sedimentary rocks, formed at the time of deposition . Sediments and sedimentary rocks are characterized by bedding, which occurs when layers of sediment, with different particle sizes are deposited on top of each other. [1] These beds range from millimeters to centimeters ...Sandstone is a sedimentary rock made of grains of sand (defined as 1/16 mm to 2 mm sized particles) that have been naturally cemented together. Grains in sandstones are unfused, and some of these grains can be dislodged by rubbing across the rock. Sandstone represents ancient stream, deltaic, or beach deposits. Uses for sandstone include ...
