We publish original studies relating to the geochemistry of natural waters and their interactions with rocks and minerals under near Earth-surface conditions. Coverage includes theoretical, experimental, and modeling papers dealing with this subject area, as well as papers presenting observations of natural systems that stress major processes. The journal also presents `letter'-type papers for rapid publication and a limited number of review-type papers on topics of particularly broad interest or current major controversy.
