摘要

A set of GPR profiles have been recorded in order to determine the 3D geometry of a prograding delta-frontsandbody (Roda sandstone formation, Eocene, Graus-Tremp basin). Common Mid Points (CMP) also havebeen recorded to obtain the velocity of the electromagnetic wave in ground. In order to build the topsurface of a 3D prism a set of topographic points have been acquired. Most of the GPR profiles are orientedparallel to the progradation direction (NNE-SSW) and show the expected geometries. The 3D prism hasbeen built from the individual profiles, which shows the three dimensional geometry of the sandy lithosome
