- •
HC affects the thermal structure at depths > 20 km with respect to models with no HC.
- •
HC does not affect the depth of eclogitization in the CNS section.
- •
HC affects the depth of eclogitization by 15 km in the EPR section.
- •
Nothwest trend in wedge hydration is not explained by changes in HC effiency.
- •
Trend is likely related to along-strike changes in water stored in the Cocos plate.
