Calcite is a natural calcium carbonate - an example of birefringence.
compound
Yes i Believe it is.
an example of one is.... ACID adding dilute HCl (hydrochloric acid) to a rock will determine if it contains calcite- a good indicator of Limestone and other rocks made from the bodies of fossilised creatures
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.
marble is a metamorphic rock and was formed by regional or contact metamorphism it is a metamorphism of limestone and dolostone. the composition is calcite and/or limestone(sedimentry rock made od calcite)
Yes, they do (unless they are really really tiny crystals of less than a few micrometer size or so, where in a few cases they might not contain a single atom of a long-lived radioactive element). None of the naturally occuring minerals is completely pure. For example calcite (CaCO3) always contains traces of magnesium, strontium, barium (and most other elements in the periodic table but at very very low concentrations). As there are about 8 * 10^22 atoms in a calcite crystal with a volume of 1 cm³, it is hardly surprising that a few of these atoms are long-lived radionuclides; in the case of calcite mostly Uranium.
Calcite is an example of a carbonate mineral.
A mineral based on calcium carbonate.
Compound elements. For example, calcite has the combination of calcium, oxygen, and carbon.

It is hardness. Calcite is harder than gypsum.

We use Mohs scale of mineral hardness to access the hardness of minerals, which calcite is one example.
