Geomagnetic depth sounding in the Northern Apennines (Italy).
Description
A Geomagnetic Depth Sounding (GDS) survey covering the Northern Apennines of Italy has been carried out
in the period 1992–94. Induction arrows maps and hypothetical event Fourier maps were constructed to obtain an
electromagnetic imaging of this area. Since the two dimensional (2-D) character comes out from those maps for
periods greater than 32 minutes, a 2-D inverse modeling was carried out. The model responses show that a deep
conductive layer (>5000 S) underlies the Apennine chain at about 20 km depth. The transition between the Adriatic
and the Tyrrhenian domains is marked by a rather sharp vertical offset in this conducting layer. In the northwest
sector of the studied area an anomalous high conductivity behavior is superimposed on the regional trend, which
corresponds to the geothermal field of Larderello-Travale.
