Using environmental isotopes and dissolved methane concentrations to constrain hydrochemical processes and inter-aquifer mixing in the Galilee and Eromanga Basins, Great Artesian Basin, Australia

•Regional inter-aquifer mixing is unlikely based on isotopic evidence.•Local inter-aquifer mixing occurs through faults as evidenced by dissolved methane data.•Carbonate dissolution and silicate weathering are the main hydrochemical processes.•Faults influence gas migration in coal seam gas basins....
