bastionide
Bastionide is a rare and distinctive mineral species, first discovered in the Bastnäs mine in Sweden. It is a complex oxide mineral, with the chemical formula (Ce,La)CO3F. The mineral is named after the Bastnäs mine, where it was found, and the suffix "-ide" indicating it is a compound of cerium and lanthanum with carbon, oxygen, and fluorine.
Bastionide crystallizes in the trigonal system, forming prismatic crystals that are typically colorless or white, but
Bastionide is of significant interest to the mining and materials science communities due to its content of
