What's the difference between calcite and dolomite??
The main component is calcium carbonate calcite, the sedimentary rock solid, porosity, low permeability, permeability of underground fluid are often not very good in them. And although the dolomite containing calcium carbonate is also large, but it contains a considerable amount of magnesium carbonate
Dolomite and calcite are carbonate rocks, but they are more common minerals in the strata, but their composition and sedimentary factors are very different
The original calcium carbonate in the geological structure changes of sedimentary process, have eroded ancient seawater, contains large amounts of magnesium ions in seawater, calcium ion and magnesium ion in calcium carbonate was carried out in part exchange, this process is called dolomitization, more fractured dolomite than calcium carbonate rocks. So the permeability is better. The difference in finding underground minerals especially helpful oil.
