AnagramsFrom Wiktionary under the GNU Free Documentation License. Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3). Like most other sedimentary rocks, limestones are composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts. Some limestones do not consist of grains at all and are formed completely by the chemical precipitation of calcite or aragonite. i.e. travertine. The solubility of limestone in water and weak acid solutions leads to karst landscapes. Regions overlying limestone bedrock tend to have fewer visible groundwater sources (ponds and streams), as surface water easily drains downward through joints in the limestone. While draining, water and organic acid from the soil slowly (over thousands or millions of years) enlarges these cracks; dissolving the calcium-carbonate and carrying it away in solution. Most cave systems are through limestone bedrock. From Wikipedia under the

Asked by dez - Wed Nov 12 09:21:15 2008 - - 3 Answers - 0 Comments A. Limestones indicate shallow warm seas at the time of deposition. Lime, CaCO3 is one of the odd substances that has its maximum solubility at low temperatures. As the water temperature goes up the solubility goes down and so the lime is precipitated- dropped out of solution. Shallow seas are more easily warmed by sun light and do not have much mixing from cold water at depth. (ANother note. Limestones also usually form a some distance from the coast. Near the coast the denser sediments drop out, the soluble lime is carried farther away from shore. This tends to show the original was shallow to a considerable distance from shore.)

Answered by zanekevin13 - Thu Mar 13 03:32:52 2008 What are the advantages and disadvantages of having a limestone quarry in your area?
Q. I need to write a letter for my homework either for or against the council building a limestone quarry in my area and I would be against it. Thanks for the help! :) Asked by Alex:) - Mon Jan 12 11:47:10 2009 - - 1 Answers - 0 Comments A. Advantages: You'll be able to purchase limestone scraps, on a cash only basis, at a very reasonable price. Limestone is great for carving gargoyles and other fine sculptures. Disadvantages: Increased traffic, pollution, and noise due to mining vehicles. Occasional blasting to shear off a ledge or get rid of a gumby poker. Damage to the ecosystem because of plant removal needed to access the seam. Mine trailing, pits, and disruption of aquifers.
