Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being limesecreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil
Two carbonate classification systems are in common use today, one by Folk and the second by Dunham . The Dunham system is based on depositional texture (that is, the amount of matrix surrounding the grains at the time of deposition).
Limestone is a sedimentary rock formed mostly of calcium carbonate. The stone can be formed by a hydrological process, dissolving calcium carbonate in carbon dioxide, or by a biological process, accumulating calcium carbonate through fossil sediments. The result of both processes gives rise to a large number of types of limestone, as shown in

According to the limestone classification established by Folk (1962), the limestones range from fossiliferous micrite to sparse biomicrite, packed biomicrite and poorly washed biosparite. /limestone_ . Limestone: Facts, Discussion Forum, and Encyclopedia Article.
History Original classification. Robert J. Dunham published his classification system for limestone in 1962. The original Dunham classification system was developed in order to provide convenient depositionaltexture based class names that focus attention on the textural properties that are most significant for interpreting the depositional environment of the rocks.

Limestone Classification Limestone is a sedimentary stone with 50% by weight calcite or calcium carbonate (CaCO3) content. However, commercial limestone usually has more than 50% calcium carbonate. Limestone is a clastic sedimentary stone. Almost all limestone is composed of grains or fragments of biologic origin, ranging from fossils or organically derived grains that weigh []

Natural wash patterns are often seen on older buildings. In limestone construction, the lighter colors will usually be closer to the stones original hues. And those natural colors can quite often be revealed by thoughtful cleaning methods, even after the passage of many years.

Limestone can occur in many colors but is usually white, gray, or black. It forms either through the accumulation and compaction of fossil shells or other calciumcarbonate based marine organisms, such as coral, or through the chemical precipitation of calcium carbonate out of sea water: used as a building stone and in the manufacture of cement

Wash limestone clean with your hose. You can also use a pressure washer, but start on the lowest setting and stand several feet back before increasing the power or moving closer, especially on limestone that is already damaged. Step 3 Spread kitty litter over oil stains, if applicable. You can also use hot soapy water, using a dish detergent
