Akvititet

Akvititet, also spelled "akvitit", is a rare, dark green to black mineral belonging to the amphibole group. It was first discovered in 1982 in the Akvitit mine in the Kola Peninsula, Russia, and is named after this locality. The mineral is characterized by its complex chemical composition, which includes sodium, calcium, magnesium, iron, and silicon, among others. Akvititet is typically found in metamorphic rocks, often associated with other amphibole minerals such as tremolite and actinolite.

The crystal structure of akvititet is monoclinic, and it exhibits a prismatic or acicular habit, often forming slender, needle-like crystals. The mineral's hardness is around 5.5 to 6 on the Mohs scale, and its specific gravity ranges from 3.1 to 3.3. Akvititet is often found in association with other minerals such as epidote, calcite, and quartz.

Due to its rarity and the specific conditions required for its formation, akvititet is not commonly used in industry or jewelry. However, it is of interest to mineralogists and collectors who appreciate its unique composition and appearance. The mineral's dark color and prismatic habit make it a distinctive addition to any mineral collection.
