摘要

Geoelectrical measurements using a vertical electrical sounding method were conducted in the southern Amman district, central Jordan. The objectives of the study were to identify formations that may present freshwater aquifers, and to estimate the relationship between groundwater resources and geological structures. Data collected at 23 locations were first interpreted with curve-matching techniques, using theoretically calculated master curves. The initial earth models were double-checked and reinterpreted using a one-dimensional inversion program to obtain the final subsurface stratigraphic units, including the water-bearing aquifer. The geoelectrical cross section showed that the subsurface consists of five geoelectric units. The aquifer is underlain by the last unit comprised of limestone (of Campanian age) of the Balqa Group deposits. The depth of the top of the Campanian limestone (B2/A7 aquifer) ranges between 180 and 290 m. The resistivity of the aquifer varies between 50 and 200 ohm m, indicating the existence of good quality water.
