Luque del Villar, Francisco Javier ; Crespo Feo, Elena ; Barrenechea, José F. ; Ortega Menor, Lorena | China University of Geosciences (Beijing) | 2012Stable carbon isotope geochemistry provides important information for the recognition of fundamental isotope exchange processes related to the movement of carbon in the lithosphere and permits the elaboration of models for the global carbon cycl[...]texto impreso
Borruel Abadía, Violeta ; López Gómez, José ; Horra del Barco, Raúl de la ; Galán Abellán, Belén ; Barrenechea, José F. ; Arche, Alfredo ; Ronchi, Ausonio ; Grette, Nicola ; Marzo Carpio, Mariano | Elsevier | 2015-05-15Until recently the climate of the Early–Middle Triassic at low latitudes was broadly considered as generally temperate-warm with no major climate oscillations. This work examines the climate of this period through a detailed study of the sedimen[...]texto impreso
Ronchi, Ausonio ; Lloret, Joan ; Gretter, Nicola ; López Gómez, José ; Horra, Raúl de la ; Barrenechea, José F. ; Arche, Alfredo | Elsevier | 2019-03In their paper, Mujal et al. (2017) describe as exceptional a section in the E Pyrenees (namely the Coll de Terrers), considering it a continental succession that continuously spans in time from the Late Permian to the Early Triassic. These auth[...]texto impreso
Luque del Villar, Francisco Javier ; Barrenechea, José F. ; Ortega Menor, Lorena ; Rodas, Magdalena ; Millward, David | The Economic Geology Research Unit | 2009The only two known graphite vein-deposits hosted by volcanic rocks (Borrowdale, United Kingdom, and Huelma, Southern Spain) show remarkable similarities and differences. The lithology, age of the magmatism and geodynamic contexts are distinct, b[...]texto impreso
Luque del Villar, Francisco Javier ; Ortega Menor, Lorena ; Barrenechea, José F. ; Millward, David ; Beyssac, Olivier ; Huizenga, Jan-Marten | Geological Society of America | 2009Recognized large occurrences of fl uid-deposited graphite displaying high crystallinity were previously restricted to high-temperature environments (mainly granulite facies terranes). However, in the extensively mined Borrowdale deposit (UK), th[...]texto impreso
López Gómez, José ; Martín González, Fidel ; Heredia, N. ; Horra, Raúl de la ; Barrenechea, José F. ; Cadenas, Patricia ; Juncal, Manuel ; Diez, José B. ; Borruel-Abadía, Violeta ; David Pedreira, David ; García-Sansegundo, Joaquín ; Farias, Pedro ; Galé, Carlos ; Lago, Marceliano ; Ubide, Teresa ; Fernández-Viej, Gabriela ; Georges Gand, Georges | Elsevier | 2019-01The Pyrenean-Cantabrian Orogen arose through the collision of the Iberian and Eurasian plates, mostly in Cenozoic times. This orogen comprises two main mountain ranges, the Pyrenees to the east, and the Cantabrian Mountains to the west. To date,[...]texto impreso
Juncal Rosales, Manuel Antonio ; Lloret, Joan ; Diez, José B. ; López Gómez, José ; Horra, Raúl de la ; Barrenechea, José F. ; Arche, Alfredo | Elsevier | 2019-02In the western European basins, the paleoflora of late Pennsylvanian-early Permian transition is still a matter of discussion in terms of its age determination and biostratigraphic ranges. This study represents a review of the Upper Carboniferou[...]texto impreso
Barrenechea, José F. ; López Gómez, José ; Horra del Barco, Raúl de la | Geological Society | 2018-05-17This study examines rainfall variations of the Mid-Carnian Pluvial Episode (CPE) based on the continental fluvial sedimentology, palaeosol and clay mineralogy records of the Stable Meseta (E Spain). In the formation examined, Manuel Fm or K2 Fm,[...]texto impreso
Lloret, Joan ; Ronchi, Ausonio ; López Gómez, José ; Gretter, Nicola ; Horra, Raúl de la ; Barrenechea, José F. ; Arche, Alfredo | Elsevier | 2018-10-15The break-up of Pangea remains one of the most interesting moments in the Earth's history. In the Pyrenees this geological moment is represented by continental successions, giving rise to a magnificent example of the creation of new basins and t[...]texto impreso
Gretter, N. ; Ronchi, A. ; López Gómez, José ; Arche, Alfredo ; Horra, R. De la ; Barrenechea, José F. ; Lago San José, Marceliano | Elsevier | 2015-11The Eastern Catalan Pyrenees form the southernmost segment of the Pyrenean Axial Zone. They experienced complex multistage process as the result of both the Variscan and the Pyrenean orogenic cycles. After the Late Palaeozoic, several small exte[...]
