“…The concept of paleogeographic reconstruction or reconstruction of past reliefs includes a series of techniques based on the study of the physical environment, from the manual extension of the tendency of the morphology in a profile to more complex models, such as the reconstruction of paleo concrete surfaces [17][18][19][20][21][22][23]. Since the surface to be reconstructed was a basin in this study, the TIN triangulation algorithm was chosen [24].…”

This paper presents a geomorphological analysis of the Tormes River during the Quaternary. The Tormes River formed in the center-west of the Iberian Peninsula in the province of Salamanca. It runs along a Cenozoic basin with basement materials and through Varisco, and consists of mainly granitic and metamorphic materials, leaving a wide stream of river terraces, both erosional and depositional, that confirm its evolution throughout the Quaternary. Geomorphological analyses using Geographic Information Systems tools, Digital terrain model high resolution (MDT05, LIDAR), Orthophotos (scale 1:5000), and geological maps (1:50,000 Series Magna) have allowed different morphologies and depositional terraces to be distinguished, namely, 19 levels of erosional terraces and 3 levels of erosion surfaces. Based on these correlations, the levels of terraces in the Tormes River between T1 (+140 m) and T7 (+75–80 m) are located in the Pleistocene, those between T8 (+58–64 m) and T14 (+18–23 m) in the Middle Pleistocene, those between T15 (+12–13 m) and T17 (+6–7 m) in the Upper Pleistocene, and those between T18 (+3 m) and T19 (+1.5 m) in the Holocene. The erosion surfaces are divided into six levels: S6 (+145 m), S5 (+150 m), S4 (+160 m), S3 (+170 m), S2 (+180 m) and S1 (+190 m) located in the Lower Pleistocene, This work performs a geomorphological mapping procedure applied to the evolutionary analysis of the landscape, so that it determines different geomorphological units allowing the relief and morphology of the terrain in past times, establishing a dynamic analysis of the landscapes.

a b s t r a c tThe Vale do Forno archaeological sites (Alpiarça, central Portugal) document the earliest human occupation in the Lower Tejo River, well established in geomorphological and environmental terms, within the Middle Pleistocene. In a staircase of six fluvial terraces, the Palaeolithic sites were found on the T4 terrace (þ24 m, above river bed) which is made of a basal Lower Gravels unit (LG) and an overlying Upper Sands unit (US). Geomorphological mapping, coupled with lithostratigraphy, sedimentology and luminescence dating (quartz-OSL and K-feldspar post-IRIR 290 ) were used in this study. The oldest artefacts found in the LG unit show crude bifacial forms that can be attributed to the Acheulian. In contrast, the US unit has archaeological sites stratigraphically documenting successive phases of an evolved Acheulian. Luminescence dating and correlation with the Marine Isotopic Stages suggest that the LG unit has a probable age of ca. 335 to 325 ka and the US unit an age of ca. 325 to 155 ka. This is in contrast to previous interpretations ascribing this terrace (and lithic industries) to the Last Interglacial and early phases of the Last Glacial. The VF3 site (Milhar os), containing Micoquian (Final Acheulian) industries (with fine and elaborated bifaces), found in a stratigraphic level located between the T4 terrace deposits and a colluvium associated with Late Pleistocene aeolian sands, is younger than 155 ka but much older than 32 ka.© 2016 Elsevier Ltd.

For Western Europe and specifically in Iberia, insights into the Palaeolithic occupation is similarly derived from its major rivers (from north to south: Douro, Tejo/Tagus, Guadiana, Guadalquivir) (e.g. Santonja and Villa, 2006). Within this context, the Vale do Forno archaeological sites (Alpiarça, in central Portugal; Fig. 1) provide the earliest and most well documented human occupation in the Lower Tejo (the Portuguese part of the Tejo basin). Lower Palaeolithic bifacial sites are common, often well represented by lithic industries. Their local stratigraphy and technological characteristics indicate successive phases of what is commonly named as the Acheulian. However, they were chronologically poorly constrained.From the Spanish border to the Atlantic coast, the Tejo crosses major faults which provide a natural geomorphological subdivision of the river into a series of valley reaches (I to V;Cunha et al., 2005). * Corresponding author.E-mail addresses: pcunha@dct.uc.pt (P.P.

“…Durante los periodos cálidos se estabilizarían las llanuras de inundación, permitiendo la expansión de bosques mediterráneos en el interior de los valles y el desarrollo de suelos con horizontes argilíticos (Bt) bien desarrollados (ej. Cien Fanegas), como sugieren los datos paleoclimáticos y edáficos en los valles del Jarama y del Tajo (Blain et al, 2012;Roquero et al, 2015). Los fenómenos de encajamiento fluvial que permiten la formación de terrazas escalonadas se desarrollarían fundamentalmente durante el inicio de los periodos fríos acorde al progresivo descenso del nivel de base asociado (bajadas del nivel del mar).…”
