Calcite reacts to acid. The best thing to do to determine if a mineral is calcite is to place a drop of dilute hydrochloric acid on a sample. If the mineral fizzes and carbon dioxide bubbles are produced, the mineral is calcite. Place a drop of dilute hydrochloric acid on the mineral. If it fizzes and carbon dioxide bubbles are produced, the mineral is calcite.

∙ 14y agoThe mineral calcite will fizz when a drop of strong vinegar is placed on it. The hardness, streak, and crystal formation would also be characteristics that could be examined to verify the identification as calcite.

∙ 14y ago1) Pour HCl acid on it. If your rock fizzes then it is calcite (This is due to the reaction of carbonate and acid). If your rock does not fizz then it is quartz.
2) Scratch your rock with a penny. If the penny scratches the rock then it is calcite. It has a much lower hardness than quartz. If the rock does not scratch then you have quartz.
3) Look at the crystal structure. I suggest you try 1) and 2). Crystal structure can vary a lot among minerals and may be hard to see to the untrained eye.

∙ 12y agoCalcite is a calcium carbonate mineral while quartz is a silicon dioxide crystal. Visually, you cannot tell the difference in the mineral composition, but you can perform a test to determine if the crystal you have is calcite. Calcium carbonate reacts with an acid to produce bubbles on the surface of the crystal. To test your sample, drop dilute hydrochloric acid, lemon juice or vinegar onto the sample and watch for bubbles. Quartz does not react to a dilute acid.

∙ 11y agoCalcite is difference from Quartz because one is harder than other the other on dissolves when in contact with acid. this is my answer

What kind of rock contains calcite?
Limestone is composed primarily of calcite.
Which mineral-calcite or quartz- is found in granite 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.
Sedimentary rock composed of the mineral calcite?
lime stone
How does calcite form?
Calcite is a common constituent of sedimentary rocks, limestone in particular, much of which is formed from the shells of dead marine organisms. Approximately 10% of sedimentary rock is limestone.
How do you test for mineral calcite?
you cut them open and check inside of the rock with a machin.
Is calcite a sedimentary?
Calcite is a mineral, not a rock. It can occur as part of rocks in any category. For instance, the sedimentary rock chalk consists almost entirely of calcite, the metamorphic rock marble consists mostly of calcite, and the igneous rock carbonatite consists mostly of calcite.
How can calcite be detected in rocks?
A rock can be tested for calcite by placing a drop on vinegar on its surface. If there is calcite present the rock will effervesce.
How do you test rocks for mineral calcite?
you cut them open and check inside of the rock with a machin.
What metamorphic rock is comprised entirely of calcite?
The metamorphic rock comprising of entirely calcite is limestone.
Is orange calcite a rock?
No, orange calcite is a kind of mineral
What kind of rock contains calcite?
Limestone is composed primarily of calcite.
Is a calcite a rock or mineral?
Calcite is a mineral, composed of calcium carbonate.
Which mineral-calcite or quartz- is found in granite rock?
Limestone is a sedimentary rock that is composed largely of the minerals calcite.
Is calcite an igneous rock?
Calcite (CaCO3) is a mineral, not a rock, which can be a constituent in rocks of all three types.
Does pumice have calcite?
No. Pumice is a volcanic rock. Volcanic rocks do not contain calcite.
How can you tell if one of the minerals in a rock is calcite?
Hydrochloric Acid- Calcite will fizz.
