Figure 6

Illustration of the diffusion time – temperature – grain size relation for SiC in an olivine matrix with X Mg   = 0.9. For a given grain size, this graph illustrates the time of SiC decomposition through diffusive equilibration with the Fe-component in olivine, effectively delimiting the temperature at which SiC could reside in a mantle with X Mg  = 0.9. For details see text.
