What else can I help you with?
Is calcite a silicate?
No, because in order to be a silicate a mineral needs to have both silicon and oxygen. The composition for calcite is CaCO3. Calcite is a carbonate mineral.
Is there carbon in rocks?
Yes, rocks can contain carbon in the form of minerals like calcite and dolomite, which are both carbonates. However, the amount of carbon in rocks may vary depending on the composition and type of rock.
How is mica and calcite be alike and how can they be different?
Mica and calcite are both minerals commonly found in Earth's crust. They both have distinct cleavage patterns, with mica typically having perfect basal cleavage and calcite having rhombohedral cleavage. However, they differ in chemical composition, as mica is a silicate mineral while calcite is a carbonate mineral. Additionally, mica displays a pearly luster and tends to be softer than calcite, which has a vitreous luster and can scratch glass.
What is the differences between calcite and quartz?
Calcite is the opaque compound calcium carbonate (CaCO3). It will dissolve in carbonic acid and will fizz in stronger acids. Quartz is the usually transparent compound silicon dioxide (SiO2). It will not dissolve in acid.
Is it true that both carbonates and oxides are minerals that contain the element oxygen?
Yes, that is true. Carbonates, such as calcite and dolomite, and oxides, such as hematite and magnetite, are mineral groups that contain the element oxygen as part of their chemical structure. Oxygen commonly combines with other elements to form minerals in Earth's crust.
Are Calcite and dolomite carbonate minerals?
Yes, both calcite and dolomite are carbonates.
Is calcite a silicate?
No, because in order to be a silicate a mineral needs to have both silicon and oxygen. The composition for calcite is CaCO3. Calcite is a carbonate mineral.
What two ores contain the same element?
Many minerals have these properties. Calcium for example is contained in both Limestone and in Dolomite. Indeed, calcium carbonate occurs in two forms - as Aragonite, and as Calcite. Iron is contained in both Hematite and in Iron Pyrites.
Is dolomite limestone?
Dolomite is a mixture of calcium and magnesium carbonates. The ratio of Ca:Mg can vary. If the Ca percentage is very high (above 90%), it is generally considered as calcite and if Mg is very high, it is considered as magnesite (not magnetite). Theoretically, dolomite should have 50:50 Ca:Mg ratio. Usually, dolomite is slightly resistive against weathering and diluted acids compared to calcite.
Minerals found in marble and limestone?
Marble is a sedimentary rock, which consist of limestone that has undergone heat and pressure metamorphosis under temperatures in excess of 1800ºF. The texture of marble depends on the form, size and uniformity of grains. The element components of marble determine the color of the stone.
How are halite and calcite alike?
Both calcite and halite are evaporate minerals.
What is the difference between calcite and aragonite?
Calcite and aragonite are both forms of calcium carbonate, but they have different crystal structures. Calcite has a trigonal crystal structure, while aragonite has an orthorhombic crystal structure. Aragonite is also slightly denser and usually forms in more unstable environments compared to 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!
Is there carbon in rocks?
Yes, rocks can contain carbon in the form of minerals like calcite and dolomite, which are both carbonates. However, the amount of carbon in rocks may vary depending on the composition and type of rock.
What type of crystal is formed by calcium carbonate?
In laboratory only one form; in the nature many minerals has the formula CaCO3. See also: http://en.wikipedia.org/wiki/Calcium_carbonate and http://www.webmineral.com/cgi-bin/search/search.pl.
How is calcite different from aragonite?
Chemically the same, calcite and aragonite have different crystal latticeworks, thus their crystals have a different appearance and have different crystal classifications, making them both independently recognized minerals.
How is mica and calcite be alike and how can they be different?
Mica and calcite are both minerals commonly found in Earth's crust. They both have distinct cleavage patterns, with mica typically having perfect basal cleavage and calcite having rhombohedral cleavage. However, they differ in chemical composition, as mica is a silicate mineral while calcite is a carbonate mineral.
