gadoliniumia
Gadoliniumia is the name given to a hypothetical rare-earth mineral that would contain gadolinium in its crystal structure. The designation is used primarily in speculative mineralogy and in thought experiments about gadolinium-rich phases, and it has no verified natural occurrence in the scientific record.
The theoretical mineral would incorporate gadolinium in the +3 oxidation state, with its framework built from
Crystal structure in these models is not fixed; possible systems include monoclinic or orthorhombic arrangements. Local
Occurrence and formation: In hypothetical contexts, gadoliniumia would be expected in granitic pegmatites or other rare-earth-rich
Physical properties and potential uses: Predicted properties include a high density due to gadolinium, a vitreous
Status: Gadoliniumia remains a hypothetical construct without peer-reviewed confirmation; its discussion serves to illustrate the diversity
