Specimen data for Phosphuranylite

Tom Mortimer catalog number: U934

Identification method: This bright yellow mineral is only weakly fluorescent. Multiple polished grain EDS analyses (BC123, BC203) showed a Ca, U phosphate. All analyses had a strong response line at about 3.3 KeV, but, inexplicably, in only one EDS analysis was this potassium (K) line identified.
