Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

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.

Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

Archaeometry, EarlyView.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

Early Bronze Age Copper Circulation in the Guadalentín and Segura Valleys (SE Spain)

Archaeometry, EarlyView.
ABSTRACT Identifying the sources of copper used in Early Bronze Age metalwork from south‐east Spain is key to resolving a long‐running debate concerning centralized control, or lack thereof, over El Argar society's economic organisation. This study provides the first substantial integrated programme of EDXRF and MC‐ICP‐MS analyses for copper‐base ...

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)

Archaeometry, 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.

Modelling Patterns of Past Inundation Processes Combining Geoarchaeology and Morphometric Hydrological Analysis in the Shashe‐Limpopo Basin, South Africa

Archaeometry, EarlyView.
ABSTRACT Riverine and valley systems across the globe have been central to the development of past urban centres. By AD 900, the Shashe and Limpopo Rivers seem to have facilitated the interaction and integration of early farming communities in southern Africa. This paper focuses on the application of geoarchaeological perspectives made available by the

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

Archaeometry, 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 ...

Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

Archaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.

Chironomid‐based summer temperature reconstruction of the Eemian–Weichselian transition at Lichtenberg, northern Germany

Boreas, EarlyView.
Understanding the temperature variability of past interglacial cycles is essential to predict future climates. We present a new summer temperature reconstruction, based on the subfossil chironomid record from a small palaeolake adjacent to the Middle Palaeolithic site of Lichtenberg, northern Germany. The record spans from the Saalian late glacial over

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...
