Limestone formation

A special sight in any cave are the strange and one-of-a-kind formations known as speleothems! Some places within the Mammoth Cave abound in wonderful formations not to be missed. In wetter areas these may be calcite formations like stalactites and stalagmites. In drier areas the cave formations may display as gypsum flowers and “snowballs”..

Fossils from Mississippian time are visible in the cave today. As the limestone was forming, bodies of gypsum (calcium sulfate) crystallized from the seawater during periods of high evaporation. The gypsum formed irregular masses within the limestone.

Chalk is a very fine grained, porous marine limestone composed almost entirely of microscopic fossils. Travertine is a freshwater sedimentary limestone that has very thin, crenu-lated layers and is commonly formed at springs. Marble is a carbonate rock, usually a marine limestone, that has beenOolite. Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite ). Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.In the most dramatic instances, karst mountains are created when acidic waterflow wears down limestone bedrock, creating cracks in the bedrock surface. Once cracks are formed, water is then able to flow more quickly and with greater force, creating underground drainage paths, which, in turn, lead to greater erosion.

Limestone formed in these environments because its main composition is calcium carbonate, which was deposited when shells and pieces of shells from small shallow water invertebrates settled down to the sea floor. Over time these calcium carbonate shell fragments lithified into a solid rock, which can be limestone or dolomite.calcareous nannoplankton. marginal marine sequence of siltstones (reddish layers at the cliff base) and (brown rocks above), , southwestern , U.S. Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation.
