13C-depleted moissanites in subduction-related rocks: tracers of slab fluids in the Earth’s mantle and a new diamond exploration tool
A magnesian low-Ti shoshonite dike intruding Archean Norwegian Terrane includes numerous grains of black, blue and gray moissanite (SiC). Moissanite contains inclusions of native Si, Fe and Al, Fe-Cr carbides, Fe-Cr-Mn alloys and diamond. The range of observed δ13C values (-24.8 to -29.6‰) is simila...
