The material collected was therefore carefully investigated.

Ref. Research Gate - Analysis in EDS and microRaman spectroscopy and single crystal X-ray diffraction (SCXRD) have allowed the characterization of the rare dingdaohengite-(Ce) among samples collected at Monte Arci ( Masullas, Central-Western Sardinia).
