Look for Tantalum in that as it might be Coltan? Nb/Ta U. Yep
the low end is a mess when you get into a rock matrix. ?Fe, Ti, and Mn should
be ban from the XRF periodic table in my opinion

Dudley, I can start to see what you meant about the clutter
at the low end. Testing a nice (what I think is) Columbite, it has gobs of
niobium and uranium. The low end is a mess. Def. need the K's for those
heavies....
