    Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris

    Streams are able to transport sediment very long distances. There are different types of material carried by a stream depending on the size and chemical properties. 1) Dissolved load - transport of ions and chemicals in solution - responsible for the saltiness of the sea. 2) Suspended Load - typically the largest load - clays, silt and fine sand

    The suspended load is the smallest size class of the total sediment load of a fluvial system. It is held in the water column as suspended material for extended periods of time. The conditions when this material is deposited are usually slow-moving water, intrusion when a higher part of the bed is encountered, or deposition in bars and on
