Investigation of a carbonaceous material in an ureilite by using SIXM

We investigate the carbonaceous material in the DaG 999 ureilite by unsing scanning/imaging X-ray microscope. Sample contains nearly the same volume of diamond and graphite. Both phases have inclusions, and frequencies are 0.0743 N/um3 and 0.0048 N/um3, respectively. RID value ranges ~14.5-16.0 implying that inclusions are Fe-bearing phase. Those results indicate that Fe-bearing phase distributes concentratively in the diamond.
