Abstract
  • During the I phase of the project the following activities have been carried out. 1- The available data have been organized within a geographic information system (ArcGIS 9.1) made up by the following data. o Seismic reflection profiles available in the study area, i.e., public multi-channel seismic reflection profiles belonging to the so-called \"Zone B\", CROP profiles, other public profiles made available by the VI.D.E.P.I. project (http://www.videpi.com); o well data; o field data in the marchigiano-abruzzese sector; o published geological and geophysical data (maps, seismic profiles, and geological cross-sections). In the central Adriatic Sea zone the seismic reflection data, originally available as paper copies have been transformed in digital segy files: Both seismic and well data (formation tops and time-depth curves) have been also loaded in Kingdom software (developed by Seismic Micro-Technology, Inc.) which is an advanced software devoted to seismic and well data interpretation. 2 - Integrated interpretation of the available data o In the Po Plain, several seismogenic sources have been already identified (e.g., ITSA050 - Poggio Rusco-Migliarino, ITSA051 - Novi-Poggio Renatico, ITGG107 - Mirandola). An improved definition of the geometry at depth of some of these thrusts has been carried out (Fig. 1) o In the central Adriatic off-shore, the seismic profiles has been interpreted to map, in two-ways times, the main seismic horizons (e.g., Top Messiniano, Top Scaglia calcarea, Top Fucoidi) and to define the geometry and the phases of tectonic activity of the recognized thrusts (Fig. 2). o In the marchigiano-abruzzese on-shore area, the interpretation of the available seismic profiles has been integrated with the results of field surveys (Fig. 3). In this way, the geometry (two ways time maps) of the main horizons belonging to both the pre- and syn-orogenis successions (top Fucoidi, top lower Pliocene, and top upper Pliocene) has been reconstructed. o Beneath the Po Plain, all the accessible seismic profiles and geological cross-sections have collected. Based on the analysis of this dataset, the geometry of the basal detachment surface of the Northern Apennines accretionary prism will be reconstructed. (literal)
