Stable isotope hydrology in fractured and detritic aquifers at both sides of the South Atlantic Ocean: Mar del Plata (Argentina) and the Rawsonville and Sandspruit river catchment areas (South Africa)
Relationships between different aquifers' types are studied by using isotopic tools. Hydrogeological behavior similarities exist at both sides of the South Atlantic Ocean. Rain infiltration is the only aquifers' recharge mechanism. The distinct detritic aquifers' grain sizes give the difference between environments.
