Granoblastic refers to a texture in metamorphic rocks where the mineral grains are interlocking and generally of similar size. When composed mainly of calcite, dolomite, or a combination of both, these rocks are classified as carbonate metamorphic rocks. The presence of calcite and dolomite indicates a formation under conditions of pressure and temperature that facilitate recrystallization of carbonate minerals. Such rocks are commonly found in regions affected by geological processes like mountain building.
What else can I help you with?
What element is present in dolomite but is not in calcite?
Dolomite contains magnesium in addition to calcium carbonate, while calcite is composed solely of calcium carbonate. The presence of magnesium in dolomite is what distinguishes it from calcite. This difference in composition contributes to the unique properties and uses of dolomite compared to calcite.
What type of metamorphic rock is composed mainly of calcite and dolomite?
Marble is a metamorphic rock that is composed mainly of calcite and dolomite. These minerals are typically formed from the metamorphism of limestone or dolostone. Marble is known for its distinctive veining and high polish.
Are Calcite and dolomite carbonate minerals?
Yes, both calcite and dolomite are carbonates.
What mineral group are calcite dolomite and rhodochrosite in?
Calcite belongs to the carbonates.
What elements is present in dolomite that is not present in calcite?
Magnesium

Calcite and dolomite and rhodochrosite are examples of what?
These minerals are examples of carbonates. Carbonates are minerals composed of carbonate ions (CO3^2-) combined with metal cations, such as calcium, magnesium, and manganese in the case of calcite, dolomite, and rhodochrosite, respectively.
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).
Are Calcite and dolomite carbonate minerals?
Yes, both calcite and dolomite are carbonates.
Is marble a metal?
No, marble is not a metal. Marble is a type of metamorphic rock that is composed primarily of calcite or dolomite minerals. Metals, on the other hand, are elements that have properties such as luster, conductivity, and malleability.
What is limestone to marble?
calcite and dolomite.
Are marble transparent?
No, marble is not transparent. It is a metamorphic rock composed primarily of minerals like calcite or dolomite, which give it a characteristic opaque appearance.
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 mineral group are calcite dolomite and rhodochrosite in?
Calcite belongs to the carbonates.
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
