Answer:
Carbonate sedimentary rocks
Explanation:
Carbonate sedimentary rocks are the rocks that are primarily comprised of carbonate minerals such as calcite or aragonite. They are formed chemically. These rocks are formed when Carbon is initially trapped with the accumulation of sediments over it in association with fossil shells. They are also formed due to the dissolution or precipitation by groundwater, depending upon the temperature, pH and dissolved ions present in the solution.
They are often marked by the presence of karst topography and caves.
Some examples of these rocks are limestone and dolomite.
