ZINCOLIBETHENITE Meaning and
Definition
-
Zincolibethenite is a mineral that occurs in hydrothermal veins and copper deposits. It is classified as a rare secondary mineral belonging to the mineral class of phosphates, arsenates, and vanadates. Zincolibethenite is known for its unique chemical composition, which primarily consists of zinc, copper, phosphorus, oxygen, and hydrogen. Its chemical formula is often represented as Zn6Cu3(PO4)4(OH)6·3H2O.
In terms of its physical characteristics, zincolibethenite typically forms as thin tabular crystals or massive aggregates of fibrous or stellate habit. It usually exhibits a vibrant blue to greenish-blue color, with a vitreous to silky luster. Furthermore, zincolibethenite has a perfect cleavage in one direction and a Mohs hardness of around 3.5, making it relatively soft.
The name "zincolibethenite" is a combination of the elements present in the mineral's composition, specifically zinc and copper, along with "libethenite," another mineral that zincolibethenite is often associated with. Its crystal structure closely resembles that of libethenite, with the only significant difference being the substitution of copper by zinc.
Due to its limited occurrence and distinctive features, zincolibethenite is highly valued among mineral collectors. Its unique color, crystal habit, and association with other minerals make it an attractive and sought-after specimen. The mineral's rarity and scientific importance also contribute to its significance in the field of mineralogy and geology.
Etymology of ZINCOLIBETHENITE
The word "zincolibethenite" is a scientific term used to name a specific mineral species. Its etymology can be broken down as follows:
1. Zinc: The first part of the word, "zinco-", is derived from the chemical element zinc. This term comes from the German word "Zink", which itself originates from the Middle High German "zinke", meaning "prong" or "tooth-like projection". The element zinc was named after the German word due to its spiky crystalline form.
2. Libethenite: The second part of the word, "libethenite", refers to the specific mineral species that zincolibethenite belongs to. Libethenite is a copper phosphate mineral that was first discovered in the town of Libethen (now Ľubietová) in Slovakia.
