Limestone is a sedimentary rock composed of calcium carbonate CaCO3. Most is formed by the accumulation and subsequent solidification of marine fossil debris but freshwater limestone deposits are also known. Marble formed by the metamorphism of limestone is an important source of calcium carbonate in South Australia as is shellgrit an unconsolidated accumulation of sea shell debris found in beach ridge deposits along the coastline. Metamorphism of the limestone will recrystallize it as marble but generally this does not effect its capacity as an industrial material.
Limestone is one of the most useful and versatile of all industrial minerals. One of its oldest uses is the manufacture of lime calcium oxide CaO. Mixtures of lime and sand have been used as mortar since the ancient Greek and Roman civilisations. When limestone is heated in a kiln to approximately 1000ordmC carbon dioxide is driven off to form quicklime which is mixed with water to create the less aggressive slaked lime or builders lime CaOH2. Slaked lime when wet and exposed to the atmosphere will absorb carbon dioxide to reform calcium carbonate which has a cementing action.

Cambrian limestone is widespread in South Australia in thick formations of the Normanville and Kanmantoo Groups on Fleurieu Peninsula and in the Mount Lofty Ranges on Yorke Peninsula and in the Hawker Group of the Flinders Ranges and Stuart Shelf. Many of these Cambrian units have undergone dolomitisation. See Dolomite commodity review.
The most important Cambrian calcium carbonate deposit in South Australia is at Penrice. In 1939 ICI Aust. Ltd commenced quarrying operations to supply calcium carbonate to its soda ash plant at Osborne. Operations were shifted to Penrice in 1950. In 1989 the soda ash plant along with the Penrice quarry and solar evaporation saltfields at Dry Creek were sold to Penrice Soda Products Pty Ltd. The quarry has recently purchased by Adelaide Brighton Cement Ltd.
Almost all calcium carbonate requirements for the Angaston cement works are met from the Penrice Quarry but Adelaide Brighton Cement Ltd retains reserves in other marble deposits in the same formation elsewhere in the region.
Extensive deposits of limestone occur on Yorke Peninsula in the Gambier Embayment of the Otway Basin the Murray Basin and in the Eucla Basin.
Sibelco Ltd has been working the Caroline limestone deposit 25 km southeast of Mount Gambier since 1979. The deposit is in the Gambier Limestone an Oligo-Miocene marine formation consisting almost wholly of bryozoal and shell remains. At Caroline the limestone is exceptionally white contains a significant silt-sized and finer carbonate fraction and is low in deleterious non-carbonate materials such as sand silt clay dolomite flint iron and manganese. The depth to water table is 8 m and overburden comprises approximately 1 m of soil and discoloured limestone.
The deposit is mined by elevating scrapers and crushed and milled on site before dispatch by road to Australian Glass Manufacturers Co. in Melbourne. About 35 000 t of glass-grade limestone are produced annually and small quantities are also sold for agricultural uses.
At Parham 65 km north of Adelaide up to 3 m thick unconsolidated Holocene shellgrit beach deposits of St Kilda Formation have been mined by scraper and screened dried and crushed on site using a hammer mill and roll crusher. Product is trucked to Adelaide for glass manufacture at Australian Glass Manufacturers Croydon plant. About 40 000 tyear of glass-grade material are produced.

Limestone is composed of material derived by both chemical and biological activities. The particles of sediment that make up a typical limestone are frequently recognizable as fossil fragments. By contrast most dolostone is crystalline. Dolostone forms when magnesium in pore water is substituted for some of the calcium in the original limestone or by direct precipitation. Most limestones of commercial importance accumulated in relatively shallow marine environments and are widely available for utilization. Carbonate rocks form about 15 percent of the earth39s sedimentary strata.
All of the dolostone and most of the limestone in Arkansas are Paleozoic in age and are present in the Ozark region. A small amount of Paleozoic limestone in the Ouachita Mountains has been quarried. A Tertiary-age limestone in the Midway Group is present in the Gulf Coastal Plain between Little Rock in Pulaski County and Benton in Saline County.
No records of annual production of limestone and dolostone are readily available from Arkansas because they are grouped with other types of rock aggregate production but yearly production tonnage is significant.
