Transfer of melts in the sub-arc mantle: Insights from high-pressure experiments and from the New Caledonia ophiolite
- Description:
- High-pressure experiments were aimed to study the interaction between slab melts and the sub-arc mantle at depth of ~100km in a range of P-T condition which are representative of the mantle wedge above subducted slab. Experiments have shown that porous reactive flow induces the formation of micas and amphibole in the pressure range of 25 to 45 kbar for 800 to 1000 degrees. This leads to a strong depletion in LILE and LREE in the residual fluid. The wet solidus obtained in our experiments is 975 degrees at 35 kbar. The composition and the mel...
