Abstract: | Although not well known, the eco-hydrological functions of deep aquifers (those having no contact with surface hydrological
events) play an important role in the hydrological regime because they can affect the type of habitats, the availability of
water and nutrients and the salinity of the medium, among other environmental features. This work aims at characterizing the
deep Tertiary hydrogeological units of the Salado sedimentary basin in the Province of Buenos Aires, Argentina, at a regional
scale, and to determine their environmental importance in the hydrological cycle. The geological characterization of the study
area is based on the drilling profiles from oil exploration wells bored by different oil companies between 1948 and 1994,
and also from the existing literature. The conclusion is that water exchange between quaternary surface aquifers in contact
with atmospheric events and deep tertiary aquifers is one of the main processes that keep the hydrologic balance of the region.
Not only is this crucial for the conservation of the numerous and well-developed ecosystems in the basin wetlands, but also
significant for the agricultural and cattle-raising activities of the region. |
