Integration of Potential Methods and Surface Data for the Construction of a Structural Section in Aitoloakarnania

Abstract

Summary A regional structural section of 120 km with NE-SW orientation has been constructed in the Dinaride-Hellenide fold and thrust belt. Due to the limited availability and low quality of the seismic sections, an integration of gravity and magnetotelluric datasets have allowed to reduce the uncertainty of the interpretation. The gravity model allowed to test different structural scenarios until a satisfactory fit between the observed field values and the calculated values from the model was achieved. This model has been sensitivity tested based on different densities obtained from well data and surface geology. The magnetotelluric method, which was especially valuable in this area due to the resistivity contrast between the different formations of the area, allowed to define the geometry of the area around an elongated evaporitic body. Both methods indicate the limited depth of this evaporates and the presence of carbonates or clastics underneath.
