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). Coll, M. López Blanco, Miguel Marcuello Pascual, Alejandro Prospecció geofísica Geomagnetisme Eocè Geophysical exploration Geomagnetism Eocene Epoch A set of GPR profiles have been recorded in order to determine the 3D geometry of a prograding delta-front sandbody (Roda sandstone formation, Eocene, Graus-Tremp basin). Common Mid Points (CMP) also have been 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 oriented parallel to the progradation direction (NNE-SSW) and show the expected geometries. The 3D prism has been built from the individual profiles, which shows the three dimensional geometry of the sandy lithosome. 2013-05-03T15:29:55Z 2013-05-03T15:29:55Z 2007 2013-05-03T15:29:55Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0213-683X https://hdl.handle.net/2445/42029 551465 spa Geogaceta, 2007, vol. 41, p. 51-54 (c) Sociedad Geológica de España, 2007 info:eu-repo/semantics/openAccess 4 p. application/pdf Sociedad Geológica de España Articles publicats en revistes (Dinàmica de la Terra i l'Oceà)
