	Metasomatism - LoveToKnow 1911 (Site not responding. Last check: 2007-10-16)
		For example a limestone may be converted into a siliceous chert, a dolomite, an ironstone, or a mass of metalliferous ores by metasomatic alteration.
		The Cleveland iron ores of Yorkshire are limestones replaced by siderite and limonite; the Whitehaven iron ores are metasomatic replacements of limestone by haematite.
		When beds of shale or sandstone are intercalated among the limestones they usually show little change, a fact which indicates that the ready solubility of the calcareous rocks was a dominating factor in determining the metasomatic deposits.

	Stone Type
		Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite).
		Limestones may vary greatly in texture and porosity from coquina, which is a matrix of oyster shells loosely cemented by calcite, to oolitic limestones and microcrystalline limestones whose structures are so fine that they can be seen only under magnification.
		Oolitic limestone consists of substantial amounts of "oolites" or "ooliths." Oolites are small spherical or sub-spherical grains of concentric calcite.

	Oolitic Limestone at Bowling Green
		The region producing the greater amount of oolitic limestone is that of Lawrence County and adjacent localities in Indiana, where the familiar Bedford oolitic limestone is extensively quarried.
		The light-gray permanent color of oolitic limestone, its massive and uniform character, and the ease with which it may be dressed, together with its resistance to weathering and pressure, place it first among all American limestones as a building material and second to none for carved and ornamental designs.
		The oolitic limestone in the vicinity of Bowling Green is in the form of a massive, homogeneous stratum 22 feet thick, overlain by a varying thickness of hard bluish limestone.

	Oolite - LoveToKnow 1911 (Site not responding. Last check: 2007-10-16)
		The Inferior Oolite of Yorkshire differs from that of the Cotteswold district; in place of the marine limestones of the latter area there is a thick series of sands and sandstones with shales and beds of coal; these deposits are mainly estuarine with occasional marine beds.
		The principal subdivisions, in descending order, are: the Scarborough or Grey Limestone series, the Middle Estuarine series with their coal seams; the Millepore series and Whitwell or Cave Oolite; the Lower Estuarine series with the Eller Beck bed and Hydraulic Limestone; the Dogger and Blea Wyke beds.
		The " slates " are brown calcareous sandstone, grey and slightly oolitic calcareous sandstone, and blue and grey oolitic limestone.

	ESKANDARI STONE - Limestone Tiles & Slabs
		Limestone is a chemical sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3).
		Limestones often contain variable amounts of silica in the form of chert or flint, as well as amounts of clay, silt and sand as disseminations, nodules, or layers within the rock unit.
		Limestone is therefore usually associated with hills and downland and occurs in regions with other sedimentary rocks, typically clays.

		Oolitic is a calcite-cemented calcareous rock, formed of shells and shell fragments from small aquatic creatures, and is noncrystailine in nature.
		Some of the better known limestones are: Carthage and Miami Valley limestone, which are crystalline limestones; Kasota, Mankota, Winona and Niagara stone, which are dolomitic limestones; and Indiana limestone, Tyndallstone, Cordova limestone, shadowvein, cottonwood and goldenshell lime stones, which are oolitic limestones.

		This unique limestone was deposited during the Eocene Epoch (55 to 38 million years ago) in a large freshwater lake and is composed of tiny oolites.
		Sanpete oolitic limestone was also used for the Kearns Mansion at 603 East South Temple (also known as the Governor's Mansion) and for the intricately carved facade of Hearst Castle at San Simeon, California.

		One only has to mention that oolitic limestone is made up of oolites and someone will pipe up "Well, what's an oolite then?" Oolites are specs of matter (often organic) that have been coated in limestone to form a small limestone grain.
		Oolitic limestone is a finely granular sedimentary rock made from billions of oolites.
		Oolitic limestone does not appear to form the caverns and sinkholes common in many limestone areas, but it does make fine building stone.

	Jurassic Coast - Open Coast
		This Kimmeridge Clay fronts an oolitic limestone crag, and as the landslip progresses, more of the crag is exposed so that there is now a prominent backscar.
		The results of the investigation indicated that joints are present within the oolitic sequence and that, as the backscar increases in height, the possibility of a major failure of the crag increases.
		This results in the toppling of limestone blocks from the exposed face which are than transported to beach level by mudslides.

	Oolitic Limestone (Site not responding. Last check: 2007-10-16)
		Limestones may be of biological origin or may result from the direct chemical precipitation of calcite from fresh water or, more often, from seawater.
		Ooids: Spherical grains resembling fish roe and found in limestones, they are formed today mostly by chemical precipitation of aragonite (a metast\able polymorph of calcium carbonate) in agitated water in shallow marine areas.
		Sediments containing ooids are said to be oolitic; on compaction and burial they may form an oolitic limestone.

		Fresh from his visits to the Bahamas and Bermuda, Agassiz thought that the oolitic limestone, evident near Key West and near Miami, was formed as eolian dunes, capping the elevated reef throughout the higher keys.
		The Key Largo Limestone and Miami Limestone have experienced a variety of alteration processes that are typical during early freshwater diagenesis of shallow-water marine carbonate sediments.
		C ages of the limestone generally fall between 20,000 and 30,000 y B.P. This indicates exchange or addition of some modern carbon with the original matrix of this rock.
