CYANOCHROITE Meaning and
Definition
-
Cyanochroite is a mineral that belongs to the sulfate mineral group. The term "cyanochroite" is derived from the Greek words "kyanos," meaning blue, and "chroma," meaning color, reflecting its intense blue coloration. It is a relatively rare mineral that occurs in oxidized ore deposits, often associated with other sulfide minerals.
Chemically, cyanochroite is known as a hydrated iron sulfate mineral, with the chemical formula Fe3(SO4)2(OH)6. It typically crystallizes in the monoclinic crystal system, forming tabular or prismatic crystals. However, it can also occur in granular or fibrous aggregates.
The exquisite blue color of cyanochroite is a result of the presence of iron in its crystal lattice, which imparts a strong absorption of certain wavelengths of visible light. Its distinctive color and crystal habit make it an attractive mineral for collectors, although it is not widely available.
In terms of physical properties, cyanochroite has a hardness ranging between 2.5 and 3.5 on the Mohs scale, indicating a relatively soft mineral. It has a vitreous to silky luster, and its streak color is pale blue. Cyanochroite is also non-radioactive and exhibits a relatively brittle tenacity.
Overall, cyanochroite is a unique and visually captivating mineral, prized for its striking blue color and occurrence in select mineral deposits worldwide.
Etymology of CYANOCHROITE
The word "cyanochroite" is derived from the combination of two Greek roots: "kyanos" meaning "blue" and "chroma" meaning "color". These roots refer to the blue color exhibited by the mineral cyanochroite.
