TURANITE Meaning and
Definition
-
Turanite is a noun that refers to a rare mineral, which is a type of chromian spinel. It is often found in ultramafic rocks, which are igneous rocks with a low silica content, and specifically in chromitite deposits associated with platinum-group elements. Turanite is named after the Turana area in the Ural Mountains of Russia, where it was first discovered.
This mineral has a chemical formula of (Fe2+,Mg)O·(Cr3+,Fe3+)2O3 and is usually dark green to brownish-black in color. It typically occurs as an octahedral crystal, but can also be found in granular or massive form. Turanite has a high hardness and a specific gravity around 4.5, making it a relatively dense mineral.
Due to its chromian spinel composition, turanite can be associated with other minerals such as chromite, magnetite, and ilmenite. It is primarily used as an ore of chromium, a crucial element in stainless steel production and other alloy compositions. However, turanite is considered a low-grade chromium ore and is not extensively mined.
The identification and study of turanite are important in geology and mineralogy, as it contributes to our understanding of ultramafic rock formation and the genesis of chromitite deposits. Its unique properties and occurrence in specific geological settings make it a valuable mineral for scientific research and industrial applications.
