Short summary
We determined the physical conditions at the time of its entrapment for an inclusion pair hosted in a Siberian diamond (Udachnaya kimberlite) and found that it equilibrated under relatively oxidized conditions, near the enstatite–magnesite–olivine–diamond (EMOD) buffer, similarly to Udachnaya xenoliths originating from comparable depths. These results can be reconciled with models suggesting relatively oxidized, water-rich CHO fluids as the most likely parents for lithospheric diamonds.
