That said, there may be a higher proportion of one cation than the other, are shown in the general chemical composition of the above chart.The higher the temperature, the greater the leniency to this rule.At higher temperatures, the molecules and the structure of dolomite excited and can expand to accept different amounts of cations.Iron (Fe ² +) can also be for both cations to an extent replaced.Generally Dolomites as a magnesium-iron ratio of at least 4:1 is defined. Sedimentology studies all types of dolomites.

Higher amounts of iron in the solution may appoint another intermediate form called ankerite solid solution, a complete solution with fixed forms dolomite.Occurrence USES Dolomite is a relatively common mineral and is a major component of sedimentary dolomite.Nesse (2000) writes, is that known as dolomite dolomite.

It will be generally formed as a limestone as a result of diagenetic alteration of calcite, but other theories of its origin in the last few centuries have been created.Nesse (2000) claims that increasing the replacement of calcite to dolomite pore space in the original limestone, dolomite beds allow serve as a reservoir rock for oil deposits can.Dolomite can also occur in hypothermal, mesothermal and epithermal veins, nuclear medicine, massive and widespread hydrothermal deposits replacement, carbonatite, marble, lime-silicate gneisses, skarn and associated regional contact and metamorphic rocks of limestone, won dolomite and other carbonate -rich sediments (Nesse, 2000; Chesterman, 1978).

Some places where is dolomite occurrence are known, the Dolomites in northern Italy, under the Abu Dhabi sabkhas, United Arab Emirates, in the ephermeral lakes of the South Australian Coorong Lagoon in the Ontario peninsula between Lakes Erie, Ontario, Huron and the Mississippi Valley.
