dipolimagneetit
Dipolimagneetit is a rare mineral belonging to the spinel group, with the chemical formula (Fe,Mg)2TiO4. It was first discovered in the Kola Peninsula, Russia, and is named for its dipolar magnetic properties and its composition, which includes iron, magnesium, and titanium. Dipolimagneetit is typically found in igneous rocks, such as gabbros and diorites, and is often associated with other minerals like magnetite, ilmenite, and pyroxenes. The mineral exhibits a black color with a metallic luster and has a hardness of approximately 5.5 on the Mohs scale. Its crystal system is cubic, and it often forms octahedral crystals, although it can also occur in massive or granular forms. Due to its magnetic properties, dipolimagneetit is sometimes used in the production of magnetic materials and in geophysical studies. Despite its rarity, dipolimagneetit is of interest to mineralogists and geologists for its unique composition and magnetic characteristics.
