IWAKIITE Meaning and
Definition
-
Iwakiite is a relatively rare mineral that belongs to the sulfate mineral group. It is named after the locality it was first discovered in, the Iwaki mine in Fukushima Prefecture, Japan. Iwakiite has a unique chemical composition, mainly consisting of copper, aluminum, and sulfur. Its chemical formula is expressed as CuAl(SO4)2(OH)4·6H2O.
Iwakiite typically occurs as small, light blue to greenish-blue crystal aggregates or crusts in hydrothermal vein deposits. It is often associated with other copper minerals such as chalcocite, malachite, and chalcopyrite. The mineral forms in low-temperature environments where copper-rich solutions interact with rocks and undergo chemical reactions, resulting in the precipitation of iwakiite.
Physically, iwakiite has a vitreous to pearly luster and a pale blue to greenish-blue color. It has a Mohs hardness of 2.5, making it a relatively soft mineral. Its crystal structure belongs to the monoclinic system.
Iwakiite has limited applications beyond its scientific interest and aesthetic value. It is primarily sought after by mineral collectors for its rarity and distinctive crystal habits. Due to its limited occurrence and relative obscurity, iwakiite is not extensively studied or utilized in industrial applications.
In summary, iwakiite is a rare sulfate mineral composed of copper, aluminum, sulfur, and water. It forms in hydrothermal vein deposits and exhibits a pale blue to greenish-blue color. Despite its limited practical applications, iwakiite is highly regarded by mineral enthusiasts for its unique crystal structure and scarcity.
Etymology of IWAKIITE
The word "iwakiite" is derived from the name of a specific location in Japan, Iwaki City, in the Fukushima Prefecture. It is named after Mount Iwaki, a well-known landmark in the region. "Iwakiite" is used to refer to a mineral species that was discovered in this area. The suffix "-ite" is commonly used in mineralogy to denote a mineral species.
