ResumoThe recent proposition for research projects over the Parana Basin area with the main purpose of evaluating the hydrogeological potential, flow patterns, chemical properties and environmental protection aspects of the Guarani Aquifer System (GAS) as conditioned by its structural framework has also led to the investigation of a highly structured area in Central-North Parana that corresponds to the overlying Serra Geral Aquifer System (SGAS) through integration of aerogeophysical, geological, hydrogeological and hydrochemical information of wells drilled in the SGAS. Processing and interpretation of data from analytical signal and horizontal gradient techniques, which are specially useful in delineating shallow sources, allowed the regional structural patterns at Ponta Grossa Arc to be refined and three new regional NW-SE lineaments are identified: Apucarana, Arapongas and Maringa. Others, NE-SW and E-W are also observed. The new magnetic-structural framework was confronted with the spatial distribution of hydrogeological (potentiometry, outflow and specific capacity) and hydrochemical parameters (Na + + K + , Ca ++ , Mg ++ ; Cl - , HCO3 - + CO3 - - , SO4 - - ; total dissolved solids and pH). The integrated interpretation allowed to recognize the regional hydrogeological and hydrochemical conditioning to the structural framework, and connection zones between SGAS and GAS as indicated by their differential water mixture rates. pH and total dissolved solids have proven to be useful indicators of water provenance.
