calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. they are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series.all members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong double refraction in
calcite group. calcite-rhodochrosite series. a very common and widespread mineral with highly variable forms and colours. calcite is best recognized by its relatively low mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent rhombohedral cleavage in most varieties.
named for an important industrial use of the mineral after the latin word calx, or calce, for “lime.”calcite is extremely common and widespread, and it is an important rock forming mineral and is common in limestone, marble, chalk, as a cement, hydrothermal veins, igneous rocks, and caves.
calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco 3). the mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". other polymorphs of calcium carbonate are the minerals aragonite and vaterite.

calcite as limestone and marble. limestone is a sedimentary rock that is composed primarily of calcite. it forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis.
