baddeleyite
/ˈbad(ə)lɪʌɪt
/noun [mass noun]

- Interestingly, their first choice of name was brazilite, but that name had already been applied to the mineral baddeleyite.
- The U content of these metamorphic baddeleyites is towards the low end of the range seen in igneous baddeleyite, but not sufficiently different to be diagnostic.
Origin
