GNGTS 2018 S essione 1.1 147 The adopted workflow has been designed to maximize the information and constraints from multidisciplinary datasets and the benefits deriving from the interaction among a great number of researchers from different disciplines. This approach, although time consuming, is expected to overcome the weaknesses that generally are observed in common 2D or 3D not multidisciplinary studies. The final 3D model will serve as a starting point for following geo-mechanical numerical simulations and will be able to give answers to many different geological and seismological issues. In this contribution, the first results of the research activities carried out within WP2 are presented together with a first discussion about some seismotectonic implications. These results derive from the integrated interpretation of deep borehole data, seismic reflection profiles, and surface geological information combined with the analysis of gravimetric and magnetic data. The interpretation step required a preliminary phase of data preparation where the ample set of data was quality-checked and homogenized to make it ready for further elaborations. As an example, the existing geological data have been harmonized and codified according to a defined regional stratigraphic and structural scheme, while a datum shift has been applied, where required, to the different seismic vintages to refer all the data to a chosen seismic reference datum. Furthermore, a careful review of the available velocity data, derived from well and seismic data, provided fundamental constraints to elaborate synthetic well logs and a 3D velocity model that will be used to depth-convert the model from the time domain. The preliminary 3D model, resulting fromWP2 team efforts, describes the overall structural architecture of the investigated area (Fig. 1). It also provides new hints on the structural style controlling the geological setting of the study area, which is still a matter of scientific debate within the scientific community (among many others, Ghisetti et al. , 1993; Bigi et al. , 2013; Scisciani et al. , 2014; Lavecchia et al. , 2017; Pizzi et al. , 2017; Buttinelli et al. , 2018; Porreca et al. , 2018) Moreover, the relationships between the geometry of the structural discontinuities Fig. 1 - 3D geological model in time domain based on integrated interpretation of deep borehole data, seismic reflection profiles, and surface geological information.
