This repository includes the output files (in Tecplot format) of the numerical models in the paper entitled "Understanding controls on hydrothermal dolomitisation: insights from 3D Reactive Transport Modelling of geothermal convection". A key to the output data provided here is summarised in Data_Benjakul_et_al_2020.xlsx. We used TOUGHREACT, a numerical simulation program developed by the Lawrence Berkeley National Laboratory (LBNL) which is available at: https://tough.lbl.gov/licensing-download/toughreact-licensing-download/ to numerically model the convection of seawater in a single fault within carbonate-hosted system. The parameters used in the numerical models are given in the paper. https://doi.org/10.5194/se-11-2439-2020 The output files from TOUGHREACT (in Tecplot format) are visualised using trexplot, a python script developed by Hamish Robertson which can be found at: https://github.com/hammytheham/trexplot (last access: 5 December 2020).
