The National Project for the creation of a three-dimensional geological model of Italy has been made possible by the collaboration of the Centre of Oceanography and Environmental Geology of Urbino University, the Geological Survey of Italy and Midland Valley Exploration. The purpose of this work is to show the methodology for building the 3D geological model of Italy as well as outlining types of analysis, which may be carried out on such a model. The geological model will be based on map Sheet 280 - Fossombrone, on the scale of 1:50,000, from the new national geological mapping program. The study sector is limited to the Monti della Cesana open anticline where Mesozoic to Paleogene passive margin carbonates and Neogene terrigenous foreland basin sediments outcrop. The data used included a 3D digital elevation model (DEM) from the topography, field data as well as a number of cross-sections. On completion of the 3D model, a geometric analysis of the drainage system and potential water/sediment flow pathways was carried out on the topography. The next stage of the project will be to integrate the geophysical data (well logs, seismic reflection profiles and gravimetric data) with the current model in order to create a more complete 3D geological model extended down to the basement.

Abstract
The National Project for the creation of a three-dimensional geological model of Italy has been made possible by the collaboration of the Centre of Oceanography and Environmental Geology of Urbino University, the Geological Survey of Italy and Midland Valley Exploration. The purpose of this work is to show the methodology for building the 3D geological model of Italy as well as outlining types of analysis, which may be carried out on such a model. The geological model will be based on map Sheet 280 - Fossombrone, on the scale of 1:50,000, from the new national geological mapping program. The study sector is limited to the Monti della Cesana open anticline where Mesozoic to Paleogene passive margin carbonates and Neogene terrigenous foreland basin sediments outcrop. The data used included a 3D digital elevation model (DEM) from the topography, field data as well as a number of cross-sections. On completion of the 3D model, a geometric analysis of the drainage system and potential water/sediment flow pathways was carried out on the topography. The next stage of the project will be to integrate the geophysical data (well logs, seismic reflection profiles and gravimetric data) with the current model in order to create a more complete 3D geological model extended down to the basement.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
