Plumbobetafite (of Hogarth 1977)
October 07, 2011 06:10PM
Now that plumbobetafite was discredited in 2010, what do I have that contains 45%U, 45%Ti, 5%Pb, and very little Ca, Nb, and Ta?

Hi Raymond,
I should to say you, that mineral with such composition hadn't any chance to be plumbobetafite even according to Hogarth' nomenclature. It was betafite according to it. Of course if it is cubic, i.e. is member of pyrochlore supergroup at all. It may be some orthorhombic uranium titanate.
Do you have complete analysis of your mineral? What is it locality? How it looks?
