This work shows preliminary results of GPR survey in the Ribeirão da Onça Basin areas, located in outcrops zones of Guarani Aquifer System, in the Parana Sedimentary Basin, São Paulo state, Brazil. Studies had as objective to characterize the subsurface, aiming to obtain saturated and unsaturated layer thickness and other hydrogeological characteristics. Preliminary GPR results obtained with 200 MHz antenna shows strong reflections corresponding to the groundwater level and a subsoil horizon which can be associated with transition from Cenozoic to Mezosoic sediments of the Botucatu Formation. The results are important to improve the understanding about geological characteristics of unsaturated layer, aquifer saturated zone definition, besides of contribute to scientifical improvement in hydrology areas and hydrogeology of outcrops zones of Guarani Aquifer System.
