The limestone is mostly made up of one of two types of mineral – calcite or aragonite. Both of these are different crystal arrangements of calcium carbonate (CaCO3). All limestones contain at least 50% calcium carbonate by weight. Limestones also contain a considerable amount of magnesium carbonate (MgCO3), also known as dolomite. Mar 13, 2018 · Composition. Limestone is defined as being primarily composed of calcium carbonate, which often comes from plant and animal material such as the shells of mollusks. Sandstone is not defined by any one substance. It consists of sand sized particles, which range from 0.0063 to 2mm in size. It often contains quartz,, though it does not have to. The rock comprises primarily calcium carbonate (CaCO3) in the form of calcite which is yet again a type of mineral. It also contains other materials like quartz ...

Crushed stone #411 #411 is a mixture of larger, fine, and dust particles.Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere. Burning fossil fuels also contributes to this.
