    Abstract

    This thesis comprises a body of work that investigates volatile recycling of C02 coupled to large-scale tectonic processes at upper mantle conditions. Specifically, we explore subduction and rifting using thermody namic and geodynamic numerical modeling techniques. The objective is to improve our understanding of the role a dynamically evolving system has in decarbonation , carbonate recycling, and storing C02 in the mantle-lithosphere by variations in key modeling parameters. We found that sedimentary diapirism is an efficient means to deliver carbon to the subarc in both hot and cold subduction zones. We also show decarbonation during rifting of continental carbonated mantle lithosphere.
