Diamond, especially micro- and nanodiamond, is a widely occurring mineral and is probably one of the most abundant forms of carbon in the Galaxy (Alexander, 2001 Allamandola et al, 1993). As such, its geochemistry has implications...

In deeper samples, the trace-element geochemistry observed in garnet inclusions in diamonds has been attributed to carbon-bearing fluids (e.g., Stachel and Harris, 1997 Wang et al., 2000 Dobosi and Kurat, 2002), although the oxidation state of the fluid (CO2- versus CH4-rich) remains open to debate.
