Calcite Meaning Properties and PowersThe Complete Guide

2 days ago · Calcite is a rock-forming mineral with a chemical formula of CaCO3. It is widespread and found throughout the world in sedimentary metamorphic and igneous rocks. Some geologists consider it to be a "ubiquitous mineral"one that is found everywhere. Calcite is classed as a carbonate and has a vitreous or glassy luster.

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.

The chemical composition of calcite is responsible for the test that is widely used to identify it especially in the field. This test is based on the fact that calcite reacts with dilute hydrochloric acid (HCl) and the reaction is manifested by vigorous effervescence. (The dilution of the HCl usually used is about 90 10 water concentrated HCl .)
