CUPROTUNGSTITE Meaning and
Definition
-
Cuprotungstite is a mineral compound that belongs to the tungstate mineral group. It is composed of copper (Cu), tungsten (W), and oxygen (O). The chemical formula of cuprotungstite is Cu2WO4(OH)2.
Cuprotungstite typically forms as a secondary mineral in oxidized hydrothermal veins, often occurring alongside other minerals such as cuprite, azurite, malachite, and native copper. It is commonly found in copper mining areas and has been discovered in various locations worldwide, including the United States, Germany, Chile, Peru, and Australia.
Physically, cuprotungstite appears as small, bluish-green to dark green crystals, which can sometimes exhibit a vitreous luster. The crystals often occur as thin tabular or prismatic shapes. Cuprotungstite has a Mohs hardness of 3.5 to 4, which means it is relatively soft.
In terms of its properties, cuprotungstite is known for its unique deep green color, which is attributed to the presence of copper. It is also distinguishable by its distinct crystal habits and relatively low hardness. Additionally, this mineral can be identified through various analytical techniques, including X-ray diffraction and electron microprobe analysis.
Due to its limited occurrence and lack of commercial significance, cuprotungstite does not have significant industrial uses or economic value. However, it is highly sought after by mineral collectors and enthusiasts who appreciate its vibrant color and rarity.
Etymology of CUPROTUNGSTITE
The word "cuprotungstite" consists of two main components: "cupro-" and "tungstite".
1. "Cupro-" is derived from the Latin word "cuprum", meaning copper. This prefix is commonly used in scientific terminology to refer to copper-related compounds.
2. "Tungstite" is derived from the element "tungsten", which comes from the Swedish words "tung" (heavy) and "sten" (stone). Tungsten is a metallic chemical element with the symbol "W" on the periodic table.
Therefore, "cuprotungstite" is a compound name that refers to a mineral containing both copper and tungsten. Its etymology is based on the key elements present in the mineral.
