Limestone is best recognized in architecture, due to the many landmarks around the world created primarily of limestone, particularly in North America and Europe. Limestone started gaining popularity during early 19th and 20th centuries. Train stations, banks and other structures from that era are usually created from limestone. It is a non-clastic sedimentary rock basically produced from the mineral calcite and sediment. The main source of limestone is the "limy ooze" shaped in oceans.
Pure limestone could be almost white. Due to its impurities, such as clay, organic remains, sand, and other materials, many limestones come in various colors, particularly on weathered surfaces. Limestone might be crystalline, clastic, granular, or huge, depending on the system of formation. Folk and Dunham classifications are described more precisely when it comes to limestones.
Travertine is a compact variety of limestone created along streams, particularly near waterfalls and around hot and cold springs. Calcium carbonate is mixed where evaporated water leaves a solution, which is supersaturated with other chemical constituents of calcite. Tufa, an absorbent or cellular form of limestone, can also be found near waterfalls. In nature, limestone is found to occur in unbalanced purity, usually as a part of the calcium molecules being restored by magnesium.
The rock holding more than 95% of calcium carbonate is known high-calcium limestone. Re-crystallized limestone takes high-quality polish and is used as a building stone. It is then known as 'marble'.
A variety of other names are related to limestone depending upon the texture, stays of foraminifera, mollusks and other shell-forming creatures. For example, oolitic, pisolitic, reostone, crinoidal, foraminiferal, calcareous ooze, bryozoa, argillaceous and hydraulic are all variations of the material known as limestone.
The colors represented here are a sampling of available materials. Additional colors are available.
