Deposition of limestone.

Limestone is a sedimentary rock that is primarily composed of Calcium carbonate in the form of calcite mineral.

They form through deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions. Limestone is the chief form of calcium carbonate rock which is dissolved by water that contains carbon dioxide, forming a calcium bicarbonate solution in caverns. The chemical formula for this reaction is: CaCO (s) 3 + H 2 OOrganic rocks that are classified as clastic, involve the deposition of plant material and formation of peat and coal deposits. The physical, chemical, or biological changes that occur during the lithification of sedimentary rocks are described by process collectively referred to as diagenesis. Sedimentary Rocks 6 Table of Contents Limestone is one familiar form of calcium carbonate. Acids in acid rain promote the dissolution of calcium carbonate by reacting with the carbonate anion. This produces a solution of bicarbonate.

Sediment transport is the movement of organic and inorganic particles by water 10. In general, the greater the flow, the more sediment that will be conveyed. Water flow can be strong enough to suspend particles in the water column as they move downstream, or simply push them along the bottom of a waterway 11.

Limestone is made up of calcium carbonate and is considered a major source of calcium for groundwater. When limestone dissolves, it releases calcium and bicarbonate ions into the groundwater, which can then be used by plants and animals. This increases the alkalinity of the water, making it better suited to supporting aquatic life.Clasts of quartzite, sandstone, limestone, granite, basalt, and gneiss are especially common. The matrix that binds the clasts together can be a mixture of sand, mud, and chemical cement. ... The environment of deposition might be along a swiftly flowing stream or a beach with strong waves.
