METAZEUNERITE Meaning and
Definition
-
Metazeunerite is a mineral that belongs to the arsenate mineral group. It is a rare secondary mineral formed from the oxidation of primary arsenide minerals in oxidized copper-arsenic deposits. It crystallizes in the orthorhombic crystal system, typically occurring as transparent to translucent prismatic crystals or as fibrous masses. Metazeunerite commonly exhibits a bright emerald-green color, which contributes to its aesthetic value and desirability among mineral collectors.
The chemical formula of metazeunerite is Cu(UO2)(AsO4)(OH)•8H2O. It contains copper (Cu), uranium (U), oxygen (O), arsenic (As), and hydroxyl (OH) ions, along with water molecules (H2O). This mineral is characterized by its monoclinic prismatic form with a vitreous luster on the crystal surfaces. The hardness of metazeunerite ranges from 2.5 to 3 on the Mohs scale, indicating its relatively low resistance to scratching.
Metazeunerite is primarily found in the oxidized zones of uranium-copper deposits, often associated with other secondary copper and uranium minerals. Its green color is attributed to the presence of copper ions, while the uranium and arsenic elements contribute to its chemical composition and crystal structure. Due to its scarcity and limited occurrence, metazeunerite holds significant value as a collector's mineral and is used for scientific research to better understand the geological processes that lead to its formation.
Etymology of METAZEUNERITE
The term "metazeunerite" is derived from a combination of two parts: "meta-" and "zeunerite".
The prefix "meta-" comes from the Greek word "meta", meaning "beyond" or "after". In scientific terminology, the prefix "meta-" is commonly used to indicate a transformation or alteration of a substance.
The second part, "zeunerite", references a mineral known as "Zeunerite". Zeunerite is a secondary mineral and a member of the uranyl phosphate group. It was named after Carl Wilhelm Correns Zeuner, a German mineralogist.
So, "metazeunerite" implies a transformation or alteration of zeunerite, suggesting a related but distinct mineral or a modification of its properties.
