Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic ( sandstone and shale are common siliciclastic rocks) sedimentary rock. Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. It can also form by chemical sedimentary processes, such as the precipitation of calcium carbonate from lake or ocean water.crystalline limestone Continental Environments Desert (Eolian) Eolian environments are arid and typically have winds that transport and sort medium- and fine-grained sediment (sand to silt). Eolian sediments are often well-sorted and show well-developed cross-bedding. Sandstone, siltstone Deltas Deltas form where rivers and streams enter larger
