| Zusammenfassung |
| In this paper we present the result of a magnetotelluric (MT) investigation
carried out across the High Agri Valley (HAV), southern Italy. Several MT
soundings were carried out in order to obtain a ~15 km long 2-D
resistivity model with an investigation depth of ~10 km. The main aim
was to provide valuable data on the geological and structural setting of the
HAV. The MT model was compared with pre-existing geological, geophysical and
seismic data. The MT model can be schematized as a superposition of three
stack lateral varying layers with different thickness and resistivity values:
a surficial low–medium resistivity layer associated with the Quaternary
deposits and to the allochthonous units; and a deeper high resistivity layer
related to the Apulia Platform, separated by a thin layer connected to the
mélange zone and to the Pliocene terrigenous marine deposits. Sharp
lateral resistivity variations are interpreted as faults that, on the basis
of accurate focal mechanism computations, display normal-faulting kinematics. |
