Palaeoclimate changes in the Afyon province, Sw-Turkey, during the Middle-Late Pleistocene: Signals from calcareous tufa pollen and stable isotope records [PDF]
, 2018 The calcareous tufas of Sarikavak located in the northern part of NE-SW trending Acigöl Graben in SW-Turkey are investigated in detail. For this aim, various analyses (stable isotopes, U/Th dating, palynology) have been carried out on samples obtained ...

Direct numerical simulations of aeolian sand ripples
, 2014 Aeolian sand beds exhibit regular patterns of ripples resulting from the interaction between topography and sediment transport. Their characteristics have been so far related to reptation transport caused by the impacts on the ground of grains entrained ...

Archaeometry, EarlyView.Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Formations quaternaires et néotectonique dans le bassin de l'Orbieu (Aude, France)
Physio-Géo, 2013 A geomorphological and sedimentological analysis makes it possible to identify the different Quaternary formations in the Orbieu valley. Then, the reconstruction of the longitudinal and transversal profiles shows the evolution of tectonic deformations ...

Archaeometry, EarlyView.ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Physio-Géo, 2008 A half-century after the P. DEMANGEON thesis (1959) and despite numerous researches concerning the southern Central Massif, there are no certitudes about the chronology of the erosion surfaces and the uplift stages of the Massif Central.

On modeling the variability of bedform dimensions [PDF]
, 2005 : Bedforms are irregular features that cannot easily be described by mean values. The variations in the geometric dimensions affect the bed roughness, and they are important in the modeling of vertical sorting and in modeling the thickness of cross ...

Boreas, EarlyView.The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the
