1960 G. Switzer & H. E. Swanson in Amer. Mineralogist 45 1272 Orthorhombic TeO2 is found in nature as tellurite. The tetragonal form, well known as a chemical compound, has been found associated with tellurite and native tellurium at Cananea, Sonora, Mexico. The name paratellurite is proposed for the new mineral.
1984 N. N. Greenwood & A. Earnshaw Chem. of Elements (1986) xvi. 911 Synthetic α-TeO2 (‘paratellurite’) forms colourless tetragonal crystals.
