WESTERVELDITE Meaning and
Definition
-
Westerveldite is a mineral that belongs to the garnet group, specifically the ugrandite series. Its chemical formula is Ca(Fe2+,Mg)Mn3+2(SiO4)3, and its crystal structure is classified as cubic. It typically occurs as small, dodecahedral crystals, which are often found embedded in metamorphic rocks.
The name "westerveldite" is derived from the location where it was first discovered, Westerveld, in the Netherlands. It was first described in 1902 by the Dutch mineralogist A. Wichmann. Westerveldite is typically black in color and has a sub-metallic to resinous luster. It possesses a relatively high density and hardness, making it a durable mineral.
This rare mineral is often found in association with other manganese-rich minerals such as rhodonite, rhodochrosite, and pyroxmangite. It is commonly observed in metamorphic manganese-rich rocks, particularly those formed in high-pressure environments. Westerveldite is also known to occur in skarn deposits and hydrothermal veins.
Due to its scarcity and limited commercial value, westerveldite is primarily sought after by mineral collectors and researchers. It is known for its distinct crystal structure, which can demonstrate interesting optical properties. While it may not hold significant economic importance, the mineral contributes to our understanding of geological processes and aids in identifying regional metamorphic conditions.
Etymology of WESTERVELDITE
The word "westerveldite" is derived from the name of the location where it was first discovered, which is Westerveld, a small village in the Netherlands. It follows the convention of mineralogical nomenclature where minerals are often named after the place of their discovery or after a prominent geologist or mineralogist associated with their identification.
