Provenance analyses on the Harbin cranium and the fossil specimens analyzed for comparison
(A) XRF element spectra.
(B) REEs. Each XRF spectrum was normalized with the signal of the Rh-Lα peak, which is generated by a Rh X-ray source. The rhinoceros maxilla and mandible from different sites were taken as control samples. The concentration patterns of the REEs were normalized by Post Archean Australian Shale (PAAS).
