A high-resolution seismic reflection survey was recently carried out in the area of the Umbria valley located north of the city of Madrid in Spain. The aim of the survey was to outline the structural framework of the near surface deposits to support a railway tunnel construction project. The field records exhibit poor reflectivity and a meticulous processing was required to achieve an adequate stack of the primary signal. Geological information from a series of nearby vertical and inclined boreholes was utilized to aid and refine the initial seismic interpretation.

Abstract
A high-resolution seismic reflection survey was recently carried out in the area of the Umbria valley located north of the city of Madrid in Spain. The aim of the survey was to outline the structural framework of the near surface deposits to support a railway tunnel construction project. The field records exhibit poor reflectivity and a meticulous processing was required to achieve an adequate stack of the primary signal. Geological information from a series of nearby vertical and inclined boreholes was utilized to aid and refine the initial seismic interpretation.| File | Dimensione | Formato | |
