Give an example of carbonate rock? what primary rock classification does this type of rock belong ? briefly explain how rock is formed

Limestones and dolomites are examples of Carbonate rocks.

Carbonate rocks belong to the sedimentary rock.

Explanation:

Carbonate rocks are comprised of many calcite mineral. This calcite may be present either due to the dissolution by groundwater or it could be present due to the groundwater precipitation, depending upon various factors such as the pH of water, temperature of water, and the amount of dissolved ions present in the solution. The carbonate rocks are formed due to the deposition and compaction of these calcite minerals. These rocks have a composition of more than 50% of carbonate minerals.

Carbonate rocks are often characterized by the presence of karst topography, sinkholes, and caves. These limestone and dolomite are two of the major carbonate rocks commonly found on earth.
