I think you have it confused, dolomite and limestones are not the same thing:
Limestone is composed of calcite or calcium carbonate, CaCO3, and dolostone is composed of dolomite or calcium magnesium carbonate, Ca,Mg(CO3).
Okla gave the chemical formula for ankerite, which is in the dolomite group.
In the field dolostone and limestone are difficult to tell apart (but there crystals are fairly diagnostic)...one way is to drop some HCl on them. Limestone will fizz (effervesce) and dolostone will not...UNLESS it is powdered...then it will fizz.
Source(s):
Manual of Mineralogy (after J.D. Dana), 19th ed., 1977, Hurlbut and Klein.Now it can happen and find them both combined in what it's called Dolomitic limestone, which is more or less 50/50 mixture of calcite and dolomite minerals.
as for carboniferous limestone, limestone is a very abundant formation, it's not exclusive to one era or one location and it can be very variant from one place to another, you have to be more specific about where this carboniferous limestone is located!
What else can I help you with?
What is the mineral in limestone?
Calcite: a common mineral consisting of crystallized calcium carbonate.
What kind of rock contains calcite?
Limestone is a common type of rock that contains calcite. Calcite is a mineral commonly found in sedimentary rocks like limestone, which is composed mainly of calcite minerals. It can also be found in marble, another rock type that consists mostly of calcite.
Is a limestone a rock or mineral?
Limestone is a rock, composed mainly of the mineral calcite.
What mineral is found in both limestone and marble?
Calcite is the mineral commonly found in both limestone and marble. Both rocks are formed primarily from calcite crystals.
Is limestone made from precipitated calcite a chemical rock?
Yes, limestone made from precipitated calcite is a chemical rock because it forms through the chemical precipitation of calcite and other minerals from water. This process typically occurs in marine environments where calcium carbonate minerals accumulate over time to form limestone rock.
What forms calcite.?
Calcite can form limestone

Which mineral-calcite ir quartz- is found in limestone rock?
Limestone is a sedimentary rock that is composed largely of the minerals calcite.
Is a limestone a rock or mineral?
Limestone is a rock, composed mainly of the mineral calcite.
Limestone is made from?
It is mostly calcite.
What is limestone to marble?
calcite and dolomite.
What rocks have calcite in them?
Limestone and Marble have calcite in them.
What mineral is found in both limestone and marble?
Calcite is the mineral commonly found in both limestone and marble. Both rocks are formed primarily from calcite crystals.
What is chemical limestone made of?
Chemical limestone can form when calcite is dissolved.
What are the sources of calcite?
For industrial uses, limestone. For collector specimens, vugs in limestone.
What are some industrial uses for calcite?
Calcite is used primarily in the forms of limestone and marble. Limestone and Marble are used for counter tops, dimension stones, and mortar. Calcite can be used to create concrete.
