Metacinnabarite meaning

Metacinnabarite definitions

Metacinnabarite is a rare mineral that is a polymorph of cinnabar. It has a cubic crystal structure and is typically found in hydrothermal veins. This mineral is identified by its deep red color, which is similar to cinnabar but slightly darker. Metacinnabarite is often associated with other sulfide minerals such as pyrite, marcasite, and sphalerite. It is considered an important ore of mercury and is mined for this purpose in some locations around the world.

Metacinnabarite is formed under specific geological conditions, typically in areas with high temperatures and pressures. It can also occur as a result of the alteration of cinnabar over time. The mineral is named after its composition, which is essentially a metacrystalline form of cinnabar.

Properties of Metacinnabarite

Metacinnabarite has a Mohs hardness of 3.5 to 4, making it relatively soft compared to other minerals. It has a specific gravity of around 7.2 and a bright red streak. When powdered, metacinnabarite exhibits a reddish-brown color. The mineral is not particularly lustrous and typically appears dull to earthy in its natural state.

Occurrence of Metacinnabarite

Metacinnabarite is found in locations where mercury deposits are present, often in association with cinnabar and other mercury ores. It is most commonly found in hydrothermal veins and areas of volcanic activity. Notable occurrences of metacinnabarite include mines in Italy, China, Spain, and the United States.

In conclusion, metacinnabarite is a fascinating mineral with unique properties and a crucial role in the mining industry. Its striking red color, association with mercury ores, and specific geological formation make it a valuable and sought-after mineral for collectors and researchers alike.
