RT Journal Article T1 Resultados preliminares en la caracterización geométrica 3D de un litosoma arenoso de progradación deltaica mediante georadar (GPR) (Fm. Arenisca de Roda, Eoceno, Cuenca de Graus-Tremp) T1 Preliminary results on the 3D geometric characterisation of a prograding delta-front sandbody with GPR (Rodasandstone, Eocene, Graus-Tremp basin) A1 Coll, Miquel A1 López Blanco, Miguel A1 Marcuello, Alex AB 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 YR 2006 FD 2006 LK http://hdl.handle.net/10272/8532 UL http://hdl.handle.net/10272/8532 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
