Depósitos y superficies de erosión asociados a los períodos interglaciares o interestadiales cuaternarios, han sido analizados utilizando cartografías geomorfológicas, datos sedimentológicos y paleontológicos. Medidas isotópicas (14C y Th/U) y datos de racemización de aminoácidos, a partir de las conchas de los moluscos, han sido utilizados con fines cronológicos. La secuencia marina más completa se desarrolla en la isla de Tenerife, y consiste en cinco terrazas marinas localizadas entre los O y 18 m (por encima del nivel medio del mar); en esta misma isla los depósitos del Ultimo Interglacial (OIS 5e) incluyen Strombus bubonius y fauna «senegalesa». Los datos sobre la isla de La Palma son preliminares, aunque dos niveles marinos diferentes pueden ser claramente diferenciados entre las cotas de O y 4 m en la costa noreste de la isla; el más reciente Holoceno y el más antiguo probablemente desarrollado durante el Ultimo Interglacial. Los valores medios de movimientos verticales de los litorales de ambas islas para los últimos 135.000 años, sugieren una ligera tendencia al hundimiento en la isla de Tenerife y un ligero levantamiento en la isla de La Palma. [ABSTRACT] Deposits and erosional marine features representing Quatemary interglaciars interstadials have been analyzed based on geological mapping, sedimentological and paleontological studies. Isotopic measurements and aminoacid racemization dating have been used for chronological purpose. The most complete marine sequence consists of five marine terraces at elevation between O m and 18 m above mean sea level (asl) in Tenerife, where deposits of the Last Interglacial (OIS 5e) include Strombus bubonius and «Senegalese» fauna. For La Palma only preliminary results are presented, but two clear marine levels can be distinguished in the Northeast coast at elevation between O m and 4 m asl; the most recent is Holocene, and the oldest, probably, developed during the Last Interglacial. The rate of vertical movements for the last -135,000 years has been calculated for both Islands, the values show a gently subsiding trend in Tenerife and a gently uplifting trend in La Palma.
The coastal archives of the last 15 ka in the Atlantic–Mediterranean Spanish linkage area: Sea level and climate changes
(Elsevier, 2008-04) Zazo Cardeña, Caridad; Dabrio, Cristino J.; Goy Goy, José Luis; Lario, Javier; Cabero del Río, Ana; Silva Barroso, Pablo Gabriel; Bardají Azcárate, Teresa; Mercier, Norbert; Borja, Francisco; Roquero, Elvira
Sea level and climate changes archived in various coastal environments during the last part of the last glacial and present interglacial periods are investigated by interpolating available geomorphology, sedimentology, palaeontology and geochronology data. The coastal response to these changes depended on the environment and geographic location. Changes of sea level during the rising, transgressive phase are well recorded in the sedimentary filling of the estuaries, whereas during the phase of highstand they are best recorded in beach–barrier environments. The postglacial rise of sea level took place in two phases: a rapid rise until 6500 cal BP, and a second phase of near stability with minor oscillations of metric magnitude. Regarding climate changes, there is no record of changing temperatures in the coastal zones of southern Spain, although there is in precipitation and wind intensity/velocity. After 7–5 cal ka BP, the general climatic trend towards aridity was punctuated by several short-lived (centennial) episodes of increased aridity that occurred with a millennial cycle, often coincident with Bond cool events and, in some cases, with decreases of sea surface temperatures. The absence of human intervention in vegetation composition until 2000 BP suggests that most environmental coastal shifts were climatically driven.
The Plio-Pleistocene boundary in southeast Spain: a review
(Elsevier, 1997) Bardají Azcárate, Teresa; Goy Goy, José Luis; Silva Barroso, Pablo Gabriel; Zazo Cardeña , Caridad; Mörner, N.A.; Somoza Losada, Luis; Dabrio, Cristino J.; Baena , J.
The Plio-Pleistocene boundary in the Mediterranean region has been defined by the entry of the so-called 'northern guests'. The absence of this characteristic cold fauna in the sedimentary record of littoral marine basins in SE Spain has led to the local establishment of this boundary by other means. Most outcropping upper Pliocene and Pleistocene marine sediments in this area have a very shallow character, resulting in the absence of the planktonic foraminiferal assemblages that characterize the upper Pliocene. As a result the only means of determining this boundary has been through regional correlation, detailed mapping and sedimentological analysis, as well as palaeomagnetism. After studies were carried out in different basins, and accepting the age of 1.64 (now recalibrated to 1.8) Ma for the Plio-Pleistocene boundary (Aguirre and Pasini, 1985), we conclude that this boundary does not bear any climatic, environmental or tectonic signature. The changes in most of these basins seem to occur either before or after this date.
Depositional history of estuarine infill during the last postglacial transgression (Gulf of Cadiz, Southern Spain)
(Elsevier Science B.V., Amsterdam., 2000) Dabrio, Cristino J.; Zazo Cardeña , Caridad; Goy Goy, José Luis; Sierro, Francisco Javier; Borja, Francisco; Lario, Javier; González Delgado, José Ángel; Flores Villarejo, José Abel
The Late Pleistocene and Holocene evolution of the estuaries in the Gulf of Cadiz is interpreted for the first time using drill cores, logs, trenches, and 38 new radiocarbon data, and the results compared with the shelf. The Odiel, Tinto and Guadalete Rivers deposited conglomerates during a highstand that did not reach the present sea level dated at ca. 25–30 ka (Isotopic Stage (IS) 3), corresponding to a relatively humid period in the area. Rivers incised these coarse-grained deposits during the last main lowstand at ca. 18 ka, when sea level dropped to -- 120 m and the coastline lay 14 km seawards from the present. The erosional surface is a sequence boundary and the flooding surface of the postglacial eustatic rise, overlain by the valley fill deposits of the transgressive and highstand phases of the last fourth- and fifth-order depositional sequences recognised in the shelf. The first marine influence in the estuaries during the transgression occurs at -25/-30 m at. ca. 10,000 years BP. According to fossil assemblages, the transgressed basins changed from brackish to more open marine as the sea rose until ca. 6500 years BP, when it reached the maximum flooding and the sandy estuarine barriers ceased to retrograde toward the muddy central basins. Then, the rate of eustatic rise decreased drastically, and the estuarine filling followed a two-fold pattern governed by the progressive change from vertical accretion to lateral (centripetal) progradation. At ca. 4000 years BP the fluvial input surpassed the already negligible rate of rise, causing partial emergence of tidal flats and spit barriers in the largely filled estuarine basins. Prevalence of coastal progradation upon vertical accretion at ca. 2400 years BP caused accelerated expansion of tidal flats and rapid growth of the sandy barriers. Further changes since the 16th century reflect widespread anthropic impacts. q2000 Elsevier Science B.V. All rights reserved.
Las dunas costeras del presente y último interglaciar en Málaga, Almería y Murcia

A beach-ridge progradation complex reflecting periodical sea-level and climate variability during the Holocene (Gulf of Almería, Western Mediterranean)
(Elsevier Science B.V., Amsterdam, 2003) Goy Goy, José Luis; Zazo Cardeña , Caridad; Dabrio, Cristino J.
Detailed mapping based on aerial photographs at various scales, analysis of morpho-sedimentary units, and radiocarbon dating of the prograding beach-ridge complex of Campo de Dalı´as (Almerı´a) allow the differentiation of six prograding units. These are called: H1, 7400–6000 cal BP; H2, 5400–4200 cal BP; H3, 4200–3000 cal BP; H4, 2700–1900 cal BP; H5, 1900– 1100 cal BP; and H6, 500 cal BP–Present. H-units are deposited during periods of high relative sea level and increased sediment input to the coast. They are bounded by large swales or erosional surfaces associated with lower sea levels and reduced input of sediment to the coast; these correspond to short periods of increased aridity inside the general arid trend recorded in the Western Mediterranean since 5.4 ka. Changes in the flux of Atlantic superficial waters into the Mediterranean Sea, and relative strength of the W/SW winds account for the recorded oscillations of relative sea level. We deduce a decadal periodicity for the deposition of a beach ridge and the adjacent swale, and suggest that it is related to fluctuations of the North Atlantic Oscillation (NAO) index and to variations of solar activity. The duration of H-units shows a quasi-millennial periodicity punctuated by short (hundred years) episodes of reduced progradation or erosion representing events of increased aridity likely to be related to Bond’s Holocene cold events.
Los piedemontes cuaternarios de la región de Almería (España). Análisis morfológico y relación con la neotectónica
(Seminario de Estudos Galegos. Area de Xeoloxía e Minería ; Instituto Universitario de Xeoloxía "Isidro Parga Pondal", 1983) Goy Goy, José Luis; Zazo Cardeña, Caridad
Se analizan en este trabajo la re1ación entre las formas que se extienden al pié de los grandes relieves de la región de A1mería y el marco estructural en el que se desarrollan. Para dicho estudio se han elegido los piedemontes de Sierra de Gádor, Sierra A1hamilla y la Sierra de la Serrata. En el primer sector, Sª de Gádor, se han distinguido siete generaciones de abanicos aluviales desarrolladas desde la regresión p1iocena, marcada por depósitos deltaicos en continuidad sedimentaria con los abanicos más antiguos de esta zona, hasta el Holoceno. La bascu1ación hacia el Norte que sufre el Campo de Dalias, acusada en el paso Pleistoceno-inferior-medio, determina junto con la distinta velocidad de e1evación del frente de sierra la disposición geométrica de estas formas. Numerosas fallas, en genera1 con juego normal aunque en algún caso presentan un cierto carácter 1evógiro, afectan a estos depósitos siendo las más representativas las de dirección N1200 E, N100 - 15 0 E, N1600 E Y E-O. Al pié de la Sª A1hamil1a se desarrollan tanto glacis como abanicos a1uvia1es,nueve generaciones. siendo los más antiguos inmediatamente posteriores a los depósitos lacustres que cierran el ciclo plioceno en el Campo de Nijar. La aparición de unas formas u otras. abanicos - glacis, parece estar condicionada al paso de un gran accidente de dirección general NO - SE que ha funcionado durante el Cuaternario como falla normal y que afectaría a la misma Serrata. La mayor parte de los depósitos están afectados por fallas siendo las más significativas las de direcci6n N100 - 150E, N1400 - 1600E, Y N400 - 45 0E. La Sª de la Serrata que constituye el frente sur del Campo de Nijar, consiste en un relieve limitado por dos grandes fallas (N400 - 45 0E, de desgarre y 1evógiras) a cuyo pié se extiende un sistema de abanicos y glacis carente de golfos, la actividad de estos accidentes continúa en la actualidad como se deduce del análisis de la red de drenaje: Desp1azamientos y desviaciones de hasta 500 metros en la cabecera de los barrancos al paso de la falla. El análisis morfológico de detalle realizado nos permite apuntar que, el desarrollo de glacis y/o abanicos aluviales, asi como la disposici6n geométrica y espacial de los mismos. está en muchos casos condicionada por la actividad neotectónica de esta región.
Oscilaciones eustáticas e implicaciones climáticas en el tránsito Neógeno-Cuaternario en la isla de Sal (archipiélago de Cabo Verde)
(Sociedad Geológica de España., 2006) Dabrio, Cristino J.; Zazo Cardeña , Caridad; González Delgado, José Ángel; Goy Goy, José Luis; Cabero del Río, Ana; Hillaire-Marcel, Claude; Ortlieb, L.; Civis Llovera, Jorge; Bardaji, T.
Solution pipes interpreted as a cryptokarst separate large-scale cross-bedded megaforms of shallowmarine calcarenites deposited at the Neogene-Quatemary transition in Cape Verde Islands. This implies that depositional phases were followed by subaerial exposure of the cemented calcarenites during subsequent falls of sea level, and accumulation of unconsolidated eolianites which supported a vegetal cover that promoted the cryptokarst. The process was repeated several times. A widespread, more recent karstification with red silty clay filling of voids may represent the aridification of climate at the beginning oi the Quaternary and the increased supply of Saharan dust by Trade Winds.
Oscilaciones del nivel del mar de largo y corto plazo: indicadores morfosedimentarios en zonas costeras
(Sociedad Geológica de España, 1996) Dabrio, Cristino J.; Zazo Cardeña, Caridad; Somoza Losada, Luis; Goy Goy, José Luis; Bardají Azcárate, Teresa; Lario, Javier; Silva Barroso, Pablo Gabriel
Sampling for dating coastal units anci quantdying processes 15 ollly possible and rewarding after detailed mapping and morphosedimentary analysis. The study of Last and Present Interglacial deposits in the Iberian Peninsula reveals that there are short-term sea-level oscillations superimposed to longerterm periodicities. Although short-term periodicities, as those observed in spit-bar units, are vital for coastal management, longer-term changes should not be discarded.
Sea level changes during the last and present interglacials in Sal Island (Cape Verde archipelago)
(Elsevier, 2010) Zazo Cardeña , Caridad; Goy Goy, José Luis; Hillaire-Marcel, Claude; Dabrio, Cristino J.; González Delgado, José Ángel; Cabero del Río, Ana; Bardají Azcárate, Teresa; Ghaleb, Bassam; Soler Javaloyes, Vicente
Last interglacial and Holocene deposits are particularly well developed in the southern parts of Sal Island (Cape Verde Archipelago). They primarily consist of low-elevation (≤2 m above sea level [a.s.l.]) marine deposits made of a basal conglomerate embedded in carbonate mud, passing upwards to calcarenites. All deposits contain an abundant fauna with corals, algae and molluscs with Strombus latus Gmelin and accompanying warm water species of the “Senegalese” fauna. Small scale geomorphological mapping with detailed morphosedimentary analysis revealed lateral facies changes and imbricate (offlapping) structures that suggest small-scale oscillations of paleo-sealevels during high sea stand intervals. U-series measurements (in coral fragments) allowed unequivocal identification of Marine Isotope Substage (MIS) 5.5 units, but were not precise enough to date the sea level oscillations of the interval. However, geomorphological data and sedimentary facies analysis suggest a double sea level highstand during the peak of the last interglacial. MIS 5.5 age deposits occur at Sal and the Canary Islands at low topographic elevations, between 1 and 2 masl. However, these values are lower than the elevations measured for the correlative terraces outcropping at the western tropical Atlantic islands, widely considered to be tectonically stable. Combining the results in this paper with earlier investigations of the “Senegalese” fauna distribution as far north as the Mediterranean basin, it is suggested that the last-interglacial oceanic temperatures in this basin, as well as the temperatures in other islands of the Eastern Atlantic and the coasts of Morocco, were warmer than modern temperatures.
