摘要：

The activation volume of silicon diffusion (Vsi) in olivine is reported for the first time. Specimens of San Carlos olivine single crystal were annealed at 1763 K and at pressures to 9 GPa in an uniaxial split-sphere apparatus. Si-30 was used as tracer and the diffusion profiles were analyzed using the resonant nuclear reaction Si-30(p,gamma). We obtain V-Si = (-1.9 +/- 2.4) x 10(-6) m(3)/mol with a more probable value close to zero.
