Resumen
New gravity data contribute to determine the geometry of the sedimentary infill in the Almanzora Corridor.
Residual gravity anomalies was considered along 2D models to establish the deep structure of the basin, taking into account the main tectonic structures that outcrop in the area. The residual anomalies are up to -5,8 mGal in the basin center and increase to the basin boundaries where outcrops metamorphic rocks.
The interaction between north vergent folds and faults, with several orientations and kinematics, determine the position of the basin basement top. The maximum sedimentary thickness is located close to the south basin border, associated to the hinge zone of the Almanzora synform. Lateral variations may be linked to NW-SE oriented faults.
