WERDINGITE Meaning and
Definition
-
Werdingite is a relatively rare mineral that belongs to the silicate mineral group. It is composed mainly of sodium, aluminum, and iron, with the chemical formula (Na,K)2(W,Fe,Al)4(Si7Al)O22(OH)2. This mineral was first discovered in the Polar Urals, Russia, and it is primarily found in pegmatites and contact metamorphic zones.
Werdingite forms as a result of hydrothermal alteration processes involving sodium-rich fluids that interact with pre-existing minerals. It typically occurs in association with other minerals such as feldspar, muscovite, and quartz. Werdingite commonly displays a dark green to black color, with a sub-metallic luster and a moderate hardness.
The crystal structure of werdingite consists of layers of tetrahedral and octahedral sheets. The tetrahedral sheet consists of silicon and aluminum atoms bonded to oxygen atoms, while the octahedral sheet contains primarily iron and aluminum atoms. These layers are connected through shared oxygen atoms.
In terms of its properties, werdingite is non-radioactive and does not possess any significant optical properties. It does not exhibit fluorescence under ultraviolet light. Due to its limited occurrence and relatively low industrial significance, werdingite is primarily sought after by mineral collectors who appreciate its unique crystal structure and rarity.
Overall, werdingite is a specialized mineral that is known for its distinctive composition and crystal structure, making it a fascinating addition to the mineral kingdom.
Etymology of WERDINGITE
The word "werdingite" is a specific mineral name in the field of geology. The etymology of this term can be traced back to its discovery and the individuals involved. Werdingite was named after Franz Werding, a German mineralogist, who first described the mineral in 1866. The suffix "-ite" is a common naming convention in mineralogy, indicating that the term refers to a mineral. Therefore, "werdingite" directly honors Franz Werding for his contribution to mineralogy and the identification of this particular mineral.
