文摘

The combination of hydrochemistry with other environmental tracers such as noble gases and uranium series dating of travertine deposits are providing new insights into the hydrogeology of the western margin of the GAB. Previous conceptual models of simple geology and geochemical evolution along flow paths have been re-examined. Our results show that a far more complex model is evolving involving complex hydrogeology, faulting and sub-basins as well as a significant vertical flow component.
