iomikite

Iomikite is a mineral belonging to the oxide group. It is chemically defined as iron titanium oxide with the formula FeTiO3. Iomikite is a rare mineral that has been found in a limited number of locations worldwide. It typically occurs in igneous rocks, particularly those of alkaline and ultramafic composition.

The mineral was first described in 1959 and named after its chemical composition, highlighting the presence of iron (Fe), titanium (Ti), and oxygen (O). Iomikite crystals are generally small and often found as disseminated grains within their host rock. It has a metallic luster and is opaque, usually appearing black or dark brown. The hardness of iomikite is typically around 5.5 on the Mohs scale.

Notable occurrences of iomikite have been reported in regions such as Russia, Canada, and Greenland. Its geological context is often associated with titanomagnetite-bearing rocks and certain types of meteorites. Due to its rarity and often microscopic size, iomikite is not of significant commercial importance. However, its presence can provide valuable insights into the geological processes and conditions under which it formed. Research into iomikite contributes to the broader understanding of mineralogy and the Earth's crustal evolution.
