CUPROCOPIAPITE Meaning and
Definition
-
Cuprocopiapite is a mineral that falls into the category of sulfates. Its name is derived from its elemental composition, which includes copper (Cu), cobalt (Co), iron (Fe), and sulfur (S). It is recognized for its vibrant and striking blue to green coloration, making it visually appealing to collectors and mineral enthusiasts.
The crystal structure of cuprocopiapite is monoclinic, and it typically occurs in the form of fine fibers or radial aggregates. It is commonly found as an efflorescence or encrustation in oxidized copper and cobalt deposits, often associated with other secondary minerals, such as malachite, azurite, chrysocolla, and various iron oxides.
Cuprocopiapite has a moderate hardness of approximately 3.5 to 4 on the Mohs scale, which means it can be scratched by a knife but not by harder minerals. It also has a vitreous to silky luster, giving it a characteristic shine.
In terms of chemical composition, cuprocopiapite consists of hydrated copper and iron sulfates, with the general formula CuFe4(SO4)6(OH)2·20H2O. This indicates the presence of water molecules, which contribute to its relatively low density and make it prone to losing water and deteriorating when exposed to dry conditions.
Given its distinctive hue and occurrence in specific geological settings, cuprocopiapite is primarily valued as a collectible mineral. It has limited industrial applications due to its relatively low abundance and vulnerability to dehydration.
Etymology of CUPROCOPIAPITE
The word "cuprocopiapite" is derived from two main components: "cupro-" and "copiapite".
1. "Cupro-" originates from the Latin word "cuprum", which means "copper". It is commonly used as a prefix in chemical compounds to indicate the presence of copper.
2. "Copiapite" refers to a mineral found in arid regions and is named after the city of Copiapó in Chile. It was first discovered there and has been identified in other areas as well. The name Copiapó, in turn, finds its roots in the indigenous Quechuan language, where "Copayapu" translates to "place of small water". This name was later transformed into "Copiapó" during the Spanish colonization.
