The calciclastic members of the Eocene Anotz Formation (Navarre, W Pyrenees): example of resedimentation processes in carbonate ramp slopes
(Sociedad Geológica de España, 2003)The four calciclastic members of the Lower-Middle Eocene Anotz Formation in the western Pyrenees, considered by some previous authors of shallow-marine origin because of their large size, massive appearance and abundant ... -
Una importante discontinuidad estratigráfica del Paleoceno de Navarra y del País Vasco: caracterización y significado
(Sociedad Geológica de España, 1990)An important stratigraphic break has been recognized in the Paleocene of Navarra and the Basque Country, which is recorded with different features, both in platform and basinal settings. lt has been correlated through ... -
Influencia del diapiro de Zarautz sobre los procesos de resedimentación paleocenos de Orio (Guipúzcoa, Cuenca Vasca)
(Sociedad Geológica de España, 1990)The influence of the Triassic Diapir of Zarautz upon the sedimentation of the coarse-grained deep-water deposits of Paleocene age situated near Orio (Gipuzkoa) is assessed by mean of a detailed geological mapping, coupled ... -

Pujalte, Victoriano; Orue Etxebarria, Xabier; Apellaniz, Estíbali; Baceta, Juan Ignacio; Payros, Aitor; Robador, Alejandro; Tosquella Angrill, Josep
(2010)
A new unit has been recognized in the Prebetic of the northern part of the Granada Province and eastern part of the Jaén Province, herein defined as La Losa Pass Fm and dated with planktonic and larger foraminifera as late ... -
Las «megaturbiditas» y otros depósitos de resedimentación carbonatada a gran escala del Eoceno surpirenaico: nuevos datos del área Urrobi-Ultzama (Navarra)
(Sociedad Geológica de España, 1994)The number of carbonate megaturbidites and related deposits in the Urrobi-Ultzama area, west part of the South-pyrenean Eocene basin, is greater than was hitherto realized. Planktonic foraminifera analyses also demonstrate ... -
Pliegues eocenos de dirección N-S en el Pirineo occidental
Payros, Aitor; Pujalte, Victoriano; Tosquella Angrill, Josep; Orue Etxebarria, Xabier (Sociedad Española de Geología, 2001)
Several N-S trending folds have been identified in the Eocene strata of the western Pyrenees. Stratigraphical and sedimentological lines of evidence show that they formed from late Ypresian to middle Lutetian times. These ... -
Rasgos erosivos y deposicionales en la zona proximal de un «Slope-Apron» carbonatado del Paleoceno Inferior (Eibar, Cuenca vasca)
(Sociedad Geológica de España, 1991)An 1.5 km wide section of the proximal part of a Paleocene carbonate slope-apron system has been reconstructed through the correlation of 10 columnar sections. lt is oriented perpendicular to the general paleocurrents and ... -
Redefinition of the Ilerdian Stage (early Eocene)
Pujalte, Victoriano; Baceta, Juan Ignacio; Schmitz, B.; Orue Etxebarria, Xabier; Payros, Aitor; Bernaola, Gilen; Apellaniz, Estíbali; Caballero, F.; Robador, Alejandro; Serra Kiel, Josep; Tosquella Angrill, Josep (Consejo Superior de Investigaciones Científicas; Universidad de Barcelona; Universidad Autónoma de Barcelona, 2009)
The Ilerdian Stage was created by Hottinger and Schaub in 1960 to accommodate a significant phase in the evo¬lution of larger foraminifera not recorded in the northern European basins, and has since been adopted by most ... -
Río Gor, comarca de Guadix, provincia de Granada: una nueva sección de referencia del Paleógeno inferior Subbético
(Universidad de Huelva, 2012)La recientemente descubierta sección de Río Gor es mucho más expandida y completa que la clásica sección de Alamedilla, a menudo considerada la sección más representativa de la sucesión del Paleógeno inferior de la Zona ... -
Secuencia evolutiva de los depósitos resedimentados eocenos de Punta Galea, Bizkaia: relevancia para determinación del sentido de transporte en láminas de «slump»
(Sociedad Geológica de España, 1997)The middle Eocene succession of Biscay contains numerous and thick intercalations ofslump-turbidite couplets. They record a simultaneous resedimentation of both deep and shallow water deposits, most probably trigered by ... -
Un sistema turbidítico Bartoniense de tipo «channel-levee» en la Cuenca de Pamplona: implicaciones tectónicas y paleogeográficas
(Sociedad Geológica de España, 1997)The Bartonian Ezkaba Sandstone, in the Pamplona Basin,.seems.to represent channel-fill deposits of a laterally migrating ch.annel-levee turbidite.system. Its silicidastic nature and its northern derivation indicate the ...
