Limestone - Wikipedia
Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Dolomite, CaMg(CO 3) 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium.Calcite in limestone is divided into low-magnesium and high-magnesium ...

In view of these behaviors, the dominant clay mineral of the limestone rocks and soil samples is kaolinite. The d (001) values for kaolinite in the clay fraction varied from 0.718 to 0.728 nm with a median value of 0.721 nm. The range for the (002) d-values was narrow (0.358-0.359 nm) compared with (001) d-values.

Limestone: Rock Uses, Formation, Composition, Pictures
What is Limestone? Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3.It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.

Limestone is converted to quicklime through calcining in rotary or vertical kilns. In the lime process, for every ton of saleable quicklime produced, about 2 tons of 'pure' limestone or up to 6 tons of impure limestone is consumed. Limestone consumption depends on the type of product, limestone purity,

Stone Testing
Exact identification of the minerals by thin section is a subjective, experience-based skill and is largely being replaced by exact methods of chemical analysis. Having both the thin section and chemical analysis is the preferred procedure, as the physical features can be seen documented on known mineral crystals or grains.
