Combustion and Pyrolysis EA-IRMS Techniques to Determine the δ<sup>2</sup>H of Diamonds. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.
