The Late Pleistocene ami Holocene evolution of the estuaries in !he Gulf of Cadiz is interpreted for the first time using drill cores, logs, trenches, and 38 new radiocarbon data, and the results compared with lhe she!f The Odie!, Tinto and Guadalete Rivers deposited conglomerales during a highstand lhat did not reach the present sea level dated al ca. 25-30 ka (Isotopic Stage (IS) 3), corresponding lo a relatively humid period in the area. Rivers incised these coarse-grained deposits during the last main lowsland at ca. 18 ka, when sea level dropped to -120 m and the coastline lay 14 km seawards from !he presenL The erosional surface is a sequence boundary and the f100ding slIrface of tl1e postglacial eustatic rise, overlain by !he valley fill deposits of the transgressive and highstand phases of the last fourth-and fif!h-order depositional sequences recognised in !he shelf The first marine int1uence in the estuaries during the transgression occurs at -25/ -30 m at ca. 10,000 years BP.

Then, the rate of eustatic rise decreased drastically, and !he estuarine filling followed a two-fold pattem govemed by the progressive change from vertical accretion to lateral (centripelal) progradation. At ca. 4000 years BP the t1uvial input surpassed !he already negligible rate of rise, causing partial emergence of tidal f1ats and spit barriers in the largely filled estuarine basins. Prevalence of coastal progradation upon vertical accretion al ca. 2400 years BP caused accelerated expansion of tidal t1ats and rapid growth of the sandy barriers. Further changes since the 16th century ref1ect widespread anthropic impacts.

“…At present, both estuaries are largely filled with sediments. It is worth indicating that we follow the concepts and definitions of incised-valley systems, valley fill, estuary fill, and estuary models used by Allen (1991), Allen and Posamentier (1993;1994), Dalrymple et al (1992;1994), and Zaitlin et al (1994).…”

“…Attempts to recognize "conventional" systems tracts, which are tied to base-level cycles, are inappropriate unless components of the fluvial succession can be correlated with marine successions downstream (e.g., Kerr et al, 1999;Figure 27). The responses of fluvial systems to allogenic forcing are complex, and have been reviewed elsewhere (e.g., Summerfield, 1985;Pitman and Golovchenko, 1988;Butcher, 1990;Miall, 1991;Schumm, 1993;Zaitlin et al, 1994;Ethridge et al, 1998;Holbrook and Schumm, 1998;Blum and Törnqvist, 2000;Catuneanu and Elango, 2001;Holbrook, 2001). …”

It has been accepted for inclusion in Papers in the Earth and Atmospheric Sciences by an authorized administrator of DigitalCommons@University of Nebraska -Lincoln. AbstractSequence stratigraphy emphasizes facies relationships and stratal architecture within a chronological framework. Despite its wide use, sequence stratigraphy has yet to be included in any stratigraphic code or guide. This lack of standardization reflects the existence of competing approaches (or models) and confusing or even conflicting terminology. Standardization of sequence stratigraphy requires the definition of the fundamental model-independent concepts, units, bounding surfaces and workflow that outline the foundation of the method. A standardized scheme needs to be sufficiently broad to encompass all possible choices of approach, rather than being limited to a single approach or model.A sequence stratigraphic framework includes genetic units that result from the interplay of accommodation and sedimentation (i.e., forced regressive, lowstand and highstand normal regressive, and transgressive), which are bounded by "sequence stratigraphic" surfaces. Each genetic unit is defined by specific stratal stacking patterns and bounding surfaces, and consists of a tract of correlatable depositional systems (i.e., a "systems tract"). The mappability of systems tracts and sequence stratigraphic surfaces depends on depositional setting and the types of data available for analysis. It is this high degree of variability in the precise expression of sequence stratigraphic units and bounding surfaces that requires the adoption of a methodology that is sufficiently flexible that it can accommodate the range of likely expressions. The integration of outcrop, core, well-log and seismic data affords the optimal approach to the application of sequence stratigraphy. Missing insights from one set of data or another may limit the "resolution" of the sequence stratigraphic interpretation. 1 2 c a t u n e a n u e t a l . i n e a r t h -science r e v i e w s 92 (2009)
