3D geological model of the Carrascal-Ferrer Aquifer

The 3D Geological Model of the Carrascal-Ferrer Aquifer is located in the northeast of Alicante Province (Spain). The aquifer spans an area of 119 km² and serves as one of the primary sources of potable and irrigation water for the La Marina Baja region. The aquifer is composed of limestones and dolomites dating from the Barremian to the Aquitanian of the Internal Prebetic of the External Zones of the Betic Cordillera. The 3D geological model was developed using the 3D Geomodeller and Gocad software. This model aims to determine the total volume of stored water reserves and to establish the geometric relationships between the differentiated aquifer units. The 3D geological model delineates seven geological units and five primary and secondary faults. Data used for constructing the 3D model include reflection seismic profiles, hydrogeological investigation boreholes, and structural geological mapping. The Carrascal-Ferrer aquifer exhibits a complex geological structure, affected by variably oriented folds, intersected by reverse faults and strike-slip faults.
