Calcite - Wikipedia

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.

Carbonate Minerals - ThoughtCo

It is harder than calcite (3.5 to 4, rather than 3, on the Mohs scale) and somewhat denser, but like calcite it responds to weak acid by vigorous bubbling. You may pronounce it a-RAG-onite or AR-agonite, though the majority of American geologists use the first pronunciation.

Calcite breaks in smooth flat surface because?

Many minerals have "cleavage" that causes them to split on flat cleavage planes. Such minerals include micas (muscovite, biotite. phlogopite), calcite, gypsum, and feldspars.

University of Minnesota’s Mineral Pages: Fluorite

Fluorite cleaves in four directions to form octahedrons, while calcite cleaves in three directions to form rhombohedra. The two share a similar hardness, but calcite will readily bubble, or effervesce, in dilute acid, while fluorite does not react to dilute acid.

Identifying Minerals: Everything You Need To Know About It

If you have a bucket of calcite, it would only weigh about 2 1/2 times as much as a bucket of water. That is why we think of metals as being “heavy”. ... Cleavage is when a mineral breaks with smooth flat surfaces. Cleavage can be described as perfect, good, imperfect, poor.

Calcite and quartz are minerals. What properties do they ...

Calcite and quartz are minerals associated with many rock types. Calcite dissolves in the presence of acids, but the same does not occur with quartz. Although calcite is widely available around the world, quartz is the second most abundant mineral in the planet, after feldspar.

Calcite is another good example, breaking along three different planes that yield blocky fragments that look like a rectangular box that has been warped – called a "rhombohedron" or, simply, "rhomb." Galena breaks along three planes at right angles to one another, producing true cubes as fragments.
