spineliryhmän
Spineliryhmän refers to a group of minerals that share a common crystal structure and are chemically related, belonging to the spinel supergroup. The general chemical formula for minerals in this group is AB2O4, where A represents a divalent cation and B represents a trivalent cation. This specific structural arrangement, known as the spinel structure, is cubic and characterized by a close-packed array of oxygen ions with cations occupying specific interstitial sites.
The most well-known mineral in this group is spinel itself, with the formula MgAl2O4. However, the spinel
Minerals within the spineliryhmän are found in a variety of geological settings, often associated with mafic
