Slab decarbonation in Tonga and Colombia subduction zones: data repository

This repository contains the datasets and model outputs. The deposit includes: (1) Datasets: thermodynamic lookup tables and carbonate solubility datasets used to compute mineral-bound H₂O/CO₂, mineral abundance and aqueous solubility of carbonate under local P-T-water conditions, and (2) ModelResults: steady-state thermo-petrological model results for the Tonga and Colombia subduction zones. These data support the analyses in the manuscript and enable independent reproduction of the main figures and quantitative results.
