Deep TDEM Study for Structural and Mining Purposes: A Case Study of the Barbastro Saline-Evaporitic Formation, Spain

The objective of this study was to obtain the deep subsurface structure a saline-evaporitic formation affected by an anticlinal structure, defining position and thickness for its future exploitation (potassium salts). To improve knowledge, geophysical methods can be applied establish detailed information on geological structures at depth. This work analyzes results time domain electromagnetic (TDEM) survey acquired over southern flank Barbastro-Balaguer Anticline present in Ebro Basin vicinity Graus (Huesca, Spain), that controls geometry Barbastro formation, interest from mining point view. A system is used, providing penetration capability down 3.0 km parametric constrained inversion lithological known borehole (Monzón-1) used resistivity model then rest points. methodology contributes improving revealing new Anticline. shows presents with ramp hanging wall close flat footwall, generally dipping SW, decreasing 1103 m 601 m, concordance previous accepted structural model. provides essential data, allowing design drilling optimization exploitations.
