It is everywhere present below ground in West Virginia and neighboring Kentucky and extends somewhat into western Maryland and southwestern Virginia . The name derives from the Greenbrier River and Valley in West Virginia. Greenbrier Limestone is in some places more than 400 feet 122 meters thick. This great thickness allows the trapping of large quantities of oil and gas. Greenbrier Limestone is subdivided into six stratigraphic units. In ascending order, they are Denmar Limestone , Taggard Shale , Pickaway Limestone , Union Limestone , Greenville Shale , and Alderson Limestone . The limestones in this interval are predominantly skeletal grainstone s or packstone s. The Pickaway and the Union contain Oolite oolitic grainstones, although they are most prevalent in the Union.

The Geomorphology mountain and hill profiles of the Limestone Alps are very varied and range from jagged peaks and rock faces to high plateau s and extensive areas of karst . They are of economic importance, not least because they are sources of drinking water and have many accessible dripstone cave dripstone and ice cave s.

Limestone is slightly soluble in water and especially in acid rain, so corrosive drainage along joints and cracks in the limestone can produce slabs called clints isolated by deep fissures called grikes or grykes , ref http www.limestone pavements.org.uk geology.html Geology and geomorphology Limestone Pavement Conservation Retrieved on 2008 06 29 ref terms derived from the North of England dialect . If the grikes are fairly straight and the clints are uniform in size, the resemblance to man made paving stones is striking, but often they are less regular. Limestone pavements that develop beneath a mantle of topsoil usually exhibit more rounded forms. Limestone pavements can be found in many previously glaciated limestone environments around the world.

Tamala Limestone is the geological name given to the widely occurring eolianite limestone deposits on the western coastline of Western Australia , between Shark Bay in the north and nearly to Albany, Western Australia Albany in the south. The rock consists of calcarenite wind blown shell fragments and quartz sand which accumulated as coastal sand dunes during the middle and late Pleistocene and early Holocene eras. As a result of a process of sedimentation and water percolating through the shelly sands, the mixture later lithification lithified when the lime content dissolved to cement the grains together. Exposed limestone formations at The Pinnacles Desert near Cervantes, Western Australia Cervantes clearly show the limestone formation through the sedimentary process. At its thickest, the Tamala Limestone comprises the massive Zuytdorp Cliffs , up to 250 m high, extending for 150 km between Kalbarri, Western Australia and south of Steep Point, Western Australia Steep Point . Commercial uses Because of its ready availability, Tamala Limestone is used extensively for landscaping and building in Western Australia and particularly for the main population centre of Perth, Western Australia Perth . The two main sub types quarried commercially are Carabooda Limestone and Moore River Limestone . The Carabooda type is from the Wanneroo, Western Australia Wanneroo Yanchep, Western Australia Yanchep region close to Perth. It has a creamier colour and is slightly denser than Moore River limestone which comes from the area around Guilderton, Western Australia Guilderton and which is darker and more textured.

The Magnesian Limestone is a suite of rocks in north east England dating from the Permian period. The outcrop stretches from Nottingham northwards through Yorkshire and into County Durham where it is exposed along the coast between Hartlepool and South Shields . ref British Geological Survey 1 625,000 scale geological maps North and South sheets 3rd edition 1979 ref The term has now been discontinued in formal use though it appears widely in popular and scientific literature on the geology of northern England. The Magnesian Limestone is now incorporated within the Zechstein Group . In the southern part of its outcrop, the former Lower Magnesian Limestone is now referred to as the Cadeby Formation . Overlying this it is the Edlington Formation formerly the Middle Permian Marl and above this the Brotherton Formation formerly the Upper Magnesian Limestone . In the north, the Lower Magnesian Limestone is now referred to as the Raisby Formation and the Middle Magnesian Limestone as the Ford Formation. The Upper Magnesian Limestone is replaced by the Roker Formation in its lower part and the Seaham Formation in its upper part with the Edlington formation between them, though in the Durham area this last is replaced by the Fordham Evaporite Formation and the Seaham Residue. Much of the Magnesian Limestone is dolomite , i.e. calcium magnesium carbonate, and has been for many years the main source of dolomite rock in Britain. It is used in connection with the production of refractory bricks but also for aggregate for road building and other construction purposes. It is also used in the production of agricultural lime. ref Aitkenhead, N. et al 2002.
