vanadiiniilmeniitille

Vanadiiniilmeniitille is a mineral species that is a member of the ilmenite group. Its chemical formula is (Fe,V)2(Ti,V)2O6, indicating that it is a solid solution series where vanadium can substitute for both iron and titanium in the ilmenite structure. This means that vanadiiniilmeniitille is not a strictly defined end-member but rather represents compositions along a spectrum. It is primarily found in igneous rocks, particularly in mafic and ultramafic intrusions. Its occurrence is often associated with titanomagnetite and ilmenite.

The physical properties of vanadiiniilmeniitille are similar to those of ilmenite, typically appearing as black, opaque crystals or grains. It possesses a metallic to submetallic luster and has a hardness that is generally around 5 to 6 on the Mohs scale. Its density is also comparable to ilmenite, often ranging from 4.5 to 4.8 g/cm³.

Vanadiiniilmeniitille is of interest in mineralogy and economic geology due to the presence of vanadium. While vanadium is often extracted from other ore minerals, the vanadium content in vanadiiniilmeniitille can contribute to the overall vanadium economy in certain geological settings. The specific vanadium content can vary significantly, influencing its potential as a vanadium resource. Due to its solid solution nature, precise classification and naming conventions for compositions within this series can sometimes be complex, relying on detailed chemical analysis.
