Calcite, dolomite and rhodochrosite are polymorphs of each other. Meaning a calcite can become a dolomite and so on. They are all also examples of calcium bearing minerals.

Is limestone a silicate mineral?

No. Dolomite is formed by the replacement of Calcium in the mineral calcite by Magnesium, giving the chemical formula (Ca,Mg)CaCO3. Rocks formed largely of calcite are called limestones, and those which show extensive Magnesium substitution in calcite are called Dolomitic limestones.


What statement best describe the hardness of the mineral dolomite?

Dolomite has a Mohs hardness of 3.5 to 4, making it relatively soft compared to many other minerals. It can be scratched easily with a knife or nail, but can scratch materials like calcite.


What is the difference between calcite and limestone?

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 rocks have carbonate in them?

Limestone and dolomite are common rocks that contain carbonate minerals. These rocks form primarily from the accumulation of calcite or aragonite for limestone, and dolomite for dolomite, often from the remains of marine organisms.

What are some related minerals to dolomite?

The mineral dolomite is classified as a carbonate mineral. Other carbonate minerals include calcite, smithsomite, rhodochrosite, cerussite, ankerite, azurite, and malachite.

What are carbonate minerals?

Examples of carbonate minerals would be calcite, dolomite, and aragonite. These are widely distributed in the Earth's crust. Less common carbonate minerals include siderite, rhodochrosite, strontianite, smithsonite, witherite, and cerussite. Minerals that are considered to be carbonates contain the carbonate ion, CO32−

What simple test can be used to distinguish between calcite and dolomite in granular form?

One simple test to distinguish between calcite and dolomite in granular form is the acid test. Calcite will react with dilute hydrochloric acid by producing bubbles of carbon dioxide gas, while dolomite will only react if powdered first. This is due to the presence of magnesium in dolomite which slows down the reaction with acid.


What element is present in dolomite that is not present in calcite?

Magnesium


What elements is present in dolomite that is not present in calcite?

Magnesium


Are chalk and coal examples of dolomite rock?

No, they are not. Dolomite ( Ca,Mg(CO3)2 ) is a carbonate mineral similar to Calcite ( CaCO3 ) Chalk consists of biogenic Calcite deposited from shells and skeletons of microorganisms in water (mostly marine), and Dolomite occurs where Magnesium (Mg) has substituted Calcium (Ca) in the crystalline lattice of Calcite. Coal on the other hand is the product of compressed organic compounds (Hydro- carbons), primarily from buried plants.


Are both calcite and dolomite carbonate minerals?

Yes, both calcite and dolomite are carbonate minerals. Calcite is primarily composed of calcium carbonate (CaCO3), while dolomite is a carbonate mineral that contains calcium magnesium carbonate (CaMg(CO3)2).


How do you differentiate between calcite and dolomite powder?

An easy test is to try to dissolve it with hydrochloric acid. Dolomite shows a much weaker reaction with acids than calcite. If this test is not conclusive one can add quinalizarin to the acid. In the case of dolomite the solution will then become blue because of a complex forming with the magnesium from the dolomite. In the case of calcite this blue colour should be either absent or very weak because calcite commonly contains only little magnesium.
