- Grain growth-control of chemical equilibration in fluid-bearing rocks: implications from Ni incorporation into synthesized dunite
抄録
Mechanism of Ni incorporation into dunite has been studied in order to simulate the compatible elements behavior in fluid-bearing rocks. Fe-free dunites were synthesized from gel powders using a piston cylinder apparatus. The gel powders were put into Pt-lined Ni capsules with water. As the run proceeded, Ni penetrated Pt liner all the way through and infiltrated into dunite in which forsterite grains were continuously growing. The sweeping of the grain boundaries that are enriched in Ni by grain boundary diffusion and surface equilibration should be responsible for more effective Ni - Mg exchange flux between fluid and olivine than by inter-diffusion from the stationary grain boundaries.
