It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz. Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.Siltstone. A siltstone is a lithified, nonfissile mudrock. In order for a rock to be named a siltstone, it must contain over 50% silt-sized material. Silt is any particle smaller than sand, 1/16 of a millimeter, and larger than clay, 1/256 of millimeter. Silt is believed to be the product of physical weathering, which can involve freezing and ...Limestone is a sedimentary rock that is primarily composed of calcium carbonate.

What Is Limestone? In order to properly understand limestone’s many locations across the globe, you have to first understand how it’s made. There are considered two methods by which limestone is created: marine creation and evaporative creation. No matter its creation process, limestone is defined by the presence of particular minerals. 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.Limestone caves. Author(s): Ross Pogson. Updated: 13/11/18. Read time: 2 minutes. Share ...
