SHUBNIKOVITE Meaning and
Definition
-
Shubnikovite is a rare and unique mineral that belongs to the group of sulfates. Its chemical formula is a hydrated copper sulfate, Cu(Fe3+ ,Al)(SO4)2(OH)6·2H2O. The name "shubnikovite" is derived from its discoverer, Yakov Fyodorovich Shubnikov, a prominent Russian mineralogist and crystallographer.
Shubnikovite typically occurs as small, prismatic or needle-like crystals, often forming dense aggregates or radiating clusters. It commonly exhibits a bluish-green or greenish-blue color, occasionally with a translucent to transparent appearance. This mineral is classified as rare and is rarely used in commercial applications due to its limited availability and relatively low economic significance.
In terms of its physical properties, shubnikovite has a vitreous luster and a relatively low hardness. It is soluble in water and exhibits a weak, pale blue streak. Its specific gravity is typically around 2.5, indicating a moderate density. Shubnikovite is primarily known for its striking crystal habits and its presence in mineral assemblages associated with ore deposits containing copper and iron.
Given its rarity and limited occurrence, shubnikovite has limited applications. However, its unique crystal structure and composition make it of interest to mineralogists, crystallographers, and collectors. The study of shubnikovite provides valuable insights into the formation processes and geochemical conditions involved in the development of copper and iron ore deposits.
Etymology of SHUBNIKOVITE
The word "shubnikovite" is named after Nikolay Vladimirovich Shubnikov, a prominent Russian crystallographer. He made significant contributions to the study of crystal structures and symmetry, particularly in the field of symmetry in twinned crystals. As a result of his work, a type of mineral was discovered and named "shubnikovite" in his honor.
