MINERALOGICAL CHARACTERISTICS

The smithsonite or zinc spar is a zinc carbonate that is usually found in the form of a stalactite or botryoidal mass. It can be colorless, white, yellow, green, pink or blue. It forms scalenohedrons and rhombohedrons, often with curves, in the shape of a grain of rice, and renicular, stalactitic, crusty or compact aggregates.

Smithsonite appears in oxidation zones of most zinc ore deposits and in adjacent calcareous rocks.

Its name comes from the founder of the Smithsonian Institution in the United States, James Smithson.
