Slab decarbonation in Tonga and Colombia subduction zones: data repository

This repository contains datasets, model outputs, and plotting scripts supporting the manuscript on water–carbon cycling in the Tonga and Colombia subduction zones. The deposit is organized into three components: (1) Datasets: geometric, thermal, and thermodynamic datasets used for modeling; (2) ModelResults: steady-state thermo-petrological model outputs for the Tonga and Colombia subduction zones; (3) PlottingScripts: GMT and MATLAB scripts for reproducing all main figures in the manuscript. These data support the analyses presented in the manuscript and enable independent reproduction of all main figures and quantitative results.
