description The main aim of the present Ph.D. thesis is to improve our understanding of carbonation processes of serpentinized peridotite and the fate of serpentinite-hosted carbon during highpressure metamorphism, in order to better constrain their role in the deep carbon cycle of subduction zones. To advance in this overall research goal, this Ph.D. thesis presents the results of two natural case studies of key processes of carbon transfer during fluid-rock interaction in subduction zones: (i) listvenites from the Baie Verte ophiolite (Newfoundland, Canada), a natural analogue for carbon storage in the forearc mantle of subduction zones by carbonation of peridotites; and (ii) meta-ophicarbonates from the Nevado-Filábride Complex (Spain), which provide unprecedented insights into the stability of carbonates during antigorite-serpentinite dehydration in a paleo-subduction terrane. The combination of field, (micro) structural, petrological and geochemical data with thermodynamic modelling sheds new light on the interaction of fluids with the hydrated mantle, which regulates the carbon mobility at forearc and subarc depths of subduction zones. By means of thermodynamic models of prograde and high-pressure infiltration-driven devolatilization reactions in serpentinite-hosted meta-carbonate rocks, this thesis further investigates the effects of electrolytic fluids and the role of open-system flux by serpentinite dehydration fluids on the fluid-mediated release of carbon in subduction zones.

Para avanzar en este objetivo general de investigación, en esta tesis se presentan los resultados de estudios de afloramientos naturales fósiles en los que se registran dos procesos clave de transferencia de carbono durante la interacción fluido-roca en zonas de subducción: (i) las listvenitas de la ofiolita de Baie Verte (Terranova, Canadá), que constituye un análogo natural del almacenamiento de carbono por carbonatación de peridotitas del manto de antearco de una zona de subducción; y (ii) los meta-oficarbonatos del complejo Nevado-Filábride (Cordillera Bética, España), que proporcionan información unica sobre la estabilidad de los carbonatos durante la deshidratación de serpentinitas con antigorita en un terreno metamórfico de paleosubducción. La combinación de datos de campo, (micro) estructurales, petrológicos y geoquímicos con modelos termodinámicos ha proporcionado una mejor comprensión de la interacción de los fluidos con el manto hidratado, que regula la movilidad del carbono en las profundidades del antearco y arco volcánico de las zonas de subducción. Mediante modelos termodinámicos de las reacciones de devolatilización en sistema cerrado y abierto, esta tesis investiga los efectos de los fluidos electrolíticos y el papel de los fluidos de deshidratación de serpentinita en la liberación de carbono en rocas carbonatadas en serpentinitas de la placa que subduce de las zonas de subducción.Thesis has been funded by the People Programme (Marie Curie Actions) of the European Union's Seventh Framework Programme FP7/2007- 2013/ under REA grant agreement n°608001, in the frame of the Marie-Curie Initial Training Network ABYSS; Funding from the Spanish “Agencia Estatal de Investigación” (AEI) under grants no.
