Learning Across the Divide: Understanding Knowledge Sharing Through Petrographic Analysis on Ceramics From the Rhine‐Meuse Delta During the Middle to Late Neolithic Transition (3400–2200 bce)

open access: yesArchaeometry, EarlyView.
ABSTRACT Vlaardingen (VL) communities on the Dutch West coast (3400–2200 bce) are part of a unique, long‐term continuity in the European Neolithic. Despite large‐scale changes in European populations during the Neolithic, the genomic diversity and cultural practices of VL communities can be retraced to the Mesolithic.

Procurement of Senonian Flint for Bladelets Production at the Early PPNB Site of Nahal Zahal in the Northern Negev Established for the First Time Using Chemical Composition Analysis

open access: yesArchaeometry, EarlyView.
ABSTRACT The hypotheses of Senonian flint to be a prime source of prehistoric “chalcedony” flint artefacts from the Negev Desert (Israel) was not investigated in detail thus far. By combining trace‐element profiling with statistical interpretation, ten flint items from Nahal Zahal, an Early Pre‐Pottery Neolithic B site in the northern Negev, were ...

Characterization of wind-blown sediment transport with height in a highly mobile dune (SW Spain)

open access: yesGeologica Acta, 2015
The Valdevaqueros dune is located at one of the windiest points of Europe, where the frequent occurrence ofstrong easterly winds has generated a highly mobile dune. Several rotating cup anemometers in vertical array anda self-designed vertical sand trap,

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Palaeowinds and depositional conditions from Holocene loess in Sweden and Finland

open access: yesBoreas, EarlyView.
The nature of deglacial and Holocene wind regimes in Fennoscandia is debated, as is the degree to which wind‐blown loess deposits exist in the region. Loess deposits in Fennoscandia are often relatively thin, discontinuous and less well‐sorted than typical loess, and questions remain over the degree of their post‐depositional reworking and the impact ...

Mechanical strength and environmental impacts of eco-self-compacting mortar containing dune sand in the Oued-Souf region of Algeria as cementitious materials

open access: yesBudownictwo i Architektura
Desertification is a major global problem, while the scarcity of renewable energy sources continues to be a growing concern. Due to the abundance of dune sand in the southern regions of the Algerian Sahara, known as dry zones, and despite the beauty of ...
