CHLORARTINITE Meaning and
Definition
-
Chlorartinite is a mineral that belongs to the carbonate group and is considered a rare secondary mineral. It is recognized for its distinct bright green color and can be found in some geological environments, such as hydrothermal veins and limestone caves.
Chemically, chlorartinite is a hydrous magnesium iron carbonate with the chemical formula (Mg,Fe^2+)(CO_3)(OH)_2·4H_2O. This formula indicates that it consists mainly of magnesium and iron ions bonded with carbonate ions and hydroxyl groups, with the addition of four water molecules.
Chlorartinite typically crystallizes in the orthorhombic crystal system, forming platy or prismatic crystals. These crystals often exhibit a pearly or vitreous luster when observed in reflected light. The mineral is transparent to translucent, and its cleavage is perfect in one direction.
In terms of its physical properties, chlorartinite has a relatively low hardness on the Mohs scale, usually around 2.5 to 3. Its specific gravity is relatively light, typically ranging from 2.2 to 2.4.
Due to its rarity and striking green color, chlorartinite is often sought after by mineral collectors and enthusiasts. It is also of interest to researchers studying hydrothermal mineralization and analyzing mineral assemblages of specific geological formations. However, it should be noted that chlorartinite's occurrence is relatively limited, and it is not considered a commercially significant mineral.
