The Utrillas Sandstone Group is an Albian to Cenomanian clastic succession which is widely spread along most areas in the Iberian Basin. In the Southwestern sector (Serranía de Cuenca) an arid braidplain was developed and connected to the Tethys[...]texto impreso
Rodríguez López, Juan Pedro ; Meléndez Hevia, Nieves ; Soria, Ana Rosa | Sociedad Geológica de España. | 2005Detailed stratigraphic sections have allowed to establish the stratigraphic architecture of the Escucha Formation in the southern limb of the asymmetrical Cueva Foradada Syncline (Oiete Subbasin, Iberian Basin, Spain). The stratigraphic correlat[...]texto impreso
López Gómez, José ; Meléndez Hevia, Nieves | Servicio de Publicaciones de la Universidad de Alcalá | 1988Se considera que la historia geológica de una zona determinada esta condicionando de manera importante la forma de vida de sus gentes, costumbres, etc., por ello vemos también la importancia de que aquélla sea de algún modo conocida . Se present[...]texto impreso

Los materiales estudiados, que son producto de la sedimentación continental en la "Cuenca de los Cameros", presentan una compleja organización interna, debido a los bruscos cambios de facies en la horizontal y a la relativa persistencia de las m[...]texto impreso
Evidences of tectonic subsidence during the deposition of the marine Villarroya de los Pinares Formation (Aptian, Urgonian Facies) is found in the marginal Las Parras sub-basin (Maestrazgo Basin, Teruel). This tectonic activity is identified by [...]texto impreso
Veloso, Fernanda M.L. ; Liesa, Carlos ; Soria, Ana R. ; Meléndez Hevia, Nieves ; Frykman, Peter | Elsevier | 2016-08The tsunami deposit (up to 3 m thick) of the Cretaceous Camarillas Formation in the Galve sub-basin (eastern Spain) is characterized by a large lateral extent (35 km(2)) and facies uniformity, consisting in fine to coarse subarkosic-arkosic sand[...]texto impreso
Chamizo Borreguero, M. ; Meléndez Hevia, Nieves ; Bermúdez Rochas, David Didier ; Poyato Ariza, Francisco J. | Sociedad Geológica de España. | 2008El análisis de las facies del Mb. Calizas de la Bicuerca (Albiense-Cenomaniense) en el ámbito de la Cuenca Ibérica Suroccidental y las relaciones existentes entre ellas sitúa el depósito de estos materiales en un ambiente mareal durante un conte[...]texto impreso
Arribas Mocoroa, María Eugenia ; Rodríguez López, Juan Pedro ; Meléndez Hevia, Nieves ; Soria de Miguel, Ana Rosa ; De Boer, Poppe | Elsevier B.V. | 2012Aeolian dune sandstones of the Iberian erg system (Cretaceous, Spain) host giant calcite concretions that constitute heterogeneities of diagenetic origin within a potential aeolian reservoir. The giant calcite concretions developed in large-scal[...]texto impreso
Rodríguez-López, Juan Pedro ; Liesa, Carlos L. ; Pardo, Gonzalo ; Meléndez Hevia, Nieves ; Soria, Ana R. ; Skilling, Ian | Elsevier | 2016-06-15The late Jurassic–early Cretaceous is commonly considered the only cold climatic interval in Earth history without any direct evidence of polar ice. A newly discovered dropstone-bearing interval from the subtropical Iberian Basin (western Tethys[...]texto impreso
A coastal marine siliciclastic unit has been studied from a palaeogeographic and structural-stratigraphic point of view. The unit was deposited during the Aptian in the extensional Las Parras sub-basin (Maestrazgo basin, E Spain), and it has bee[...]texto impreso
Se han estudiado materiales sedimentarios continentales de la Sierra de Altomira meridional atribuidos recientemente al Cretácico Inferior en Facies Weald. Se distinguen dos unidades litoestratigráficas que denominamos: unidad inferior de lutita[...]texto impreso
Aurell, Marcos ; Fregenal Martínez, María Antonia ; Bádena, B. ; Muñoz-García, María Belén ; Élez Villar, Javier ; Meléndez Hevia, Nieves ; De Santisteban, Carlos | Elsevier | 2019-12The Middle Jurassic-Early Cretaceous tectono-sedimentary evolution of the southwestern part of the intraplate Iberian Basin (Spain) was mostly controlled by the Alto Tajo-Montes Universales (ATMU) and Landete-Teruel (LT) faults. During the Middl[...]texto impreso
A coastal siliciclastic unit was deposited during the Aptian at the base ofVillarroya de los Pinares Formation in Las Parras sub-basin. It can be subdivided in four coarsening-upwards coastal sequences. We focus in the third sequence (S3), which[...]texto impreso
Veloso, Fernanda M.L ; Frykman, Peter ; Nielsen, Carsten M. N. ; Soria, Ana Rosa ; Meléndez Hevia, Nieves | Elsevier | 2016-12In this study, we examined two sandstones bodies of the Camarillas Fm. The porosity and permeability models of each sandstone body, the tsunami deposit at the bottom and the barrier island – tidal inlet deposit at the top, supplied two independe[...]
