Limestone formed.

Limestone. Limey shale overlaid by limestone, in Cumberland Plateau, Tennessee. Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate, CaCO 3 ). It makes up about ten percent of the total volume of all sedimentary rocks. A unique feature of this rock is that its main constituent, calcite, is produced chiefly ...Limestone is a type of rock that is made up of bits of animal shells. Over millions of years these shells collected on the ocean floor. As layers of shells and mud built up, the lower layers slowly hardened into limestone.Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. It can also form by chemical sedimentary processes, such as the precipitation of calcium carbonate from lake or ocean water.Using this information, explain what the environment of deposition was like at the time of limestone formation and how the mineral in the limestone formed? ( ...During the formation of Rodinia, the Grenville Series sediments were squeezed and pushed up onto the continental margin, forming the Grenville Mountains. The intensity of compression metamorphosed the sedimentary rocks; sandstone became quartzite , gneiss, or schist, limestone became marble , and shale became gneiss and …

The pre-Cambrian dolomite formation of the Baraboo' syn- clinal is singularly fine grained. The Niagara limestone of Wis- consin, a dolomitic formation, is generally a very even-textured, fine-grained, and compact rock. The generalization may be deduced from the facts cited that many undisturbed or only slightly disturbed dolomites are exceed-Metalimestone Blair Athol Formation. Psammite, pellite.

The Fencepost Limestone Member lies above the Pfeifer Shale Member in the upper part of the Greenhorn Limestone Formation and below the Fairport Chalk Member in the lower part of the Carlile Shale. The Fencepost Limestone has several unique features. It occurs over a large area in a relatively uniform thickness of approximately …Limestone forms in a deep marine environment from precipitation of calcium carbonate. Shale is made of fine clay particles, and therefore indicates deposition in relatively still water. In contrast, sandstone is made of slightly larger grains and therefore deposition of sand can happen in water that is moving slowly.Limestone is precipitated calcium carbonate (CaCO 3). Limestone is the primary component of much of the central United States. One problem with chemical sedimentary rocks is that it is very easy for water to re-dissolve them. Sink holes form where water has dissolved limestone in the ground, forming a cave which then collapses.Limestone is forming in the Caribbean Sea, Indian Ocean, Persian Gulf, Gulf of Mexico, around Pacific Ocean islands, and within the Indonesian archipelago. There are many different names used for limestone. These names are based upon how the rock formed, its appearance or its composition, and other factors.

Limestone is found all over the world. Dover, England, is famous for its white cliffs made of chalk, a soft form of limestone. Not all limestone is soft, however. Marble is a type of hard limestone that was formed by great pressure and heat in Earth’s crust. Limestone is used to make cement, roads, and fertilizer.
