Abstract

Summary

A seismic line acquired near Gorizia (NE of Italy) and long about 3.3 km was reprocessed and interpreted with the aim to investigate the buried geological structures and the tectonic of the area.

The seismic profile well images the structures buried by the Quaternary alluvial deposits. In particular are well imaged the top of the flysch at about 100 m in depth and a dipping reflector from South to North that can be related to the limestone. The flysch outcrops in the south part of the seismic line in correspondence of the Farra hill., and is affected by compressional and transpressional tectonic deformation. Also tomographic inversion of refracted and diving waves was performed, allowing us to define the velocities of the alluvial deposits and of the flysh. Also the structural setting of the embricated thrusts are well imaged by the final velocity field obtained by tomographic inversion.
