n: a chemical combination of calcium, magnesium, carbon, and oxygen, CaMgCO3. It is the main constituent of dolomite. Compare calcium carbonate.

n: 1. a salt of carbonic acid. 2. a compound containing the carbonate radical (CO3) 3. a carbonate rock.

n: The different carbonate of alkaline earth element.

any of the many rocks composed of calcium carbonate (limestone) or magnesium carbonate (dolomite) or other acid soluble rocks with a common CO3-2 ionic charge. The pores may be poorly connected and matrix permeability (non fractures) are often much lower

n: a sedimentary rock composed primarily of calcium carbonate (calcite) or calcium magnesium carbonate (dolomite).

n: A kind of sedimentary rock whose content of carbonate is over 50%. Mainly consisted of calcite, dolomite and ankerite.

abbr: dolomite;used in drilling reports.

n: a type of sedimentary rock similar to limestone but containing more than 50 percent magnesium carbonate;sometimes a reservoir rock for petroleum.

n: A kind of natural compound whose can be expressed by CaCO3.MgCO3


calcium/magnesium carbonate rock. Dolomite is formed by chemical modification of a limestone.

crystals of dolomite in the pore space. May turn loose when acidized and become migrating fines.

n: the shrinking of the solid volume of rock as limestone turns to dolomite, i.e., the conversion of limestone to dolomite rock by replacement of a portion of the calcium carbonate with magnesium carbonate.

n: rock composed of dolomite.

n: classify formation by ingredients and characters,such as
sandstone,shale, limestone and dolomite rock and so on.

n: A carbonate sedimentary rock predominantly composed of calcite of organic, chemical or detrital origin. Minor amounts of dolomite, chert and clay are common in limestones. Chalk is a form of fine-grained limestone.
