Muñoz García, María Belén ; Martín Chivelet, Javier ; Rossi Nieto, Carlos ; Ford, D.C. ; Schwarcz, H.P. | Universidad Complutense de Madrid | 2007New insight into the timing and structure of the Last Interglacial Period (Eemian) was obtained through U-Th dating of four speleothems from Northern Spain and an analysis of their stable isotope records. The four stalagmites examined were colle[...]texto impreso
Morad, Daniel ; Nader, Fadi H. ; Gasparrini, Marta ; Morad, Sadoon ; Rossi Nieto, Carlos ; Marchionda, Elisabetta ; Darmaki, Fatima Al ; Martines, Marco ; Hellevang, Helge | Elsevier | 2018-05This petrographic, stable isotopic and fluid inclusion microthermometric study of the Upper Jurassic limestones of an onshore field, Abu Dhabi, United Arab Emirates (UAE) compares diagenesis in flanks and crest of the anticline. The results reve[...]texto impreso
Caja Rodríguez, Miguel Ángel ; Marfil, Rafaela ; Salas del Mármol, Rafael ; Rossi Nieto, Carlos | Sociedad Geológica de España. | 2001A thick succession of Lower Cretaceous, predominantly continental clastic sediments ("Weald" facies) crop out in the westernmost sub-basins of the Maestrazgo Basin (eastern Iberian Range, Spain). 62 sandstone samples from the Mora, Castellar, an[...]texto impreso
Rossi Nieto, Carlos ; Kälin, Otto ; Arribas Mocoroa, José ; Tortosa, A. | Elsevier Science Ltd | 2002The Triassic TAGI (Trias Argilo-Gréseux Inférieur) fluvial sandstones are the main oil reservoirs in the Berkine Basin, Algeria. Nonetheless, their provenance and diagenesis, and their impact on reservoir quality, are virtually unknown. Samples [...]texto impreso

Mechanical compaction is the main porosity-reducing process in sandstones, including high-reservoir-quality rigid-grain sandstones. For such sandstones, the extrapolation of theoretical or experimental compaction algorithms needs calibration wit[...]texto impreso
Despite the paleoclimatic relevance of primary calcite to aragonite transitions in stalagmites, the relative role of fluid Mg/Ca ratio, supersaturation and CO3 2 concentration in controlling such transitions is still incompletely understood. Acc[...]texto impreso
Morad, Daniel ; Nader, Fadi H. ; Morad, Sadoon ; Rossi Nieto, Carlos ; Gasparrini, Marta ; Alsuwaidi, Mohammad ; Al Darmaki, Fatima ; Hellevang, Helge | Elsevier | 2019-08Limited thermochemical sulfate reduction (TSR) in hot (130–160°C) and anhydrite-rich sour gas reservoir carbonates of the Arab Formation (Upper Jurassic) is manifested by rare calcitization of anhydrite with slightly lower ?13CVPDB values (?3.2 [...]texto impreso

La sucesión thanetiense (Paleoceno superior) en el valle de Áger (Prepirineo de Lérida) está formada por depósitos continentales y marinos someros y representa en conjunto una secuencia transgresiva formada a su vez por 8 secuencias de orden men[...]texto impreso
Rossi Nieto, Carlos ; Villalaín, Juan José ; Lozano, Rafael P. ; Hellstrom, John C. | Elsevier | 2016-05The steeply-dipping-dolostone-hosted caves of the Sierra de Arnero (N Spain) contain low-gradient relict canyons with up to ten mapped levels of ferromanganese stromatolites and associated wall notches over a vertical range of 85 m, the highest [...]texto impreso
To evaluate possible connections between climate and the Earth's magnetic field, we examine paleoclimate proxies in a stalagmite (PA-8) recording the Blake excursion (?112–?116.4 ka) from Cobre cave (N Spain). Trace element, ?13C, ?18O, ?234U, f[...]texto impreso
Baeza, Eleuterio ; Lozano, Rafael P. ; Rossi Nieto, Carlos | Union Internationale de Spéléologie | 2018-05Sampling stalagmites for paleoclimatic study can enter into conflict with preserving the beauty and integrity of caves. To minimize this impact, a variety of sampling strategies have been used by researches aware of cave-conservation issues. Bas[...]texto impreso
Osete López, María Luisa ; Martín Chivelet, Javier ; Rossi Nieto, Carlos ; Edwards, R. Lawrence ; Egli, Ramon ; Muñoz García, María Belén ; Wang, Xianfeng ; Pavón Carrasco, Francisco Javier ; Heller, Friedrich | Elsevier Science B.V., Amsterdam | 2012One of the most important developments in geomagnetism has been the recognition of polarity excursions of the Earth’s magnetic field. Accurate timing of the excursions is a key point for under standing the geodynamo process and for magnetostr[...]
