The first data set suggesting the precursor ultra-deep conditions are carbon phases, including a micro-diamond grain obtained by the mineral separation process and various graphitic carbons. Synchrotron X-ray fluorescence analysis indicates that this diamond contains Fe-Ni metal (taenite structure) and Cu-Zn-rich phases (possibly sulfide) as inclusion. In particular, the latter phase supports the natural origin of this diamond, although the aggregation state of nitrogen in the diamond is very similar to the synthetic one.
