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.

Mapping Palaeolithic Imprints: Spatial Analysis of Hand Stencils in El Castillo Cave (Spain) Through Geomatic Techniques

Archaeometry, EarlyView.
ABSTRACT We present the application of a new quantitative approach to space study in Palaeolithic cave art. Using GIS, we analysed the distribution and position of hand stencils in El Castillo cave to track the gestures and behaviours of Palaeolithic societies.

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

Archaeometry, EarlyView.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Between Gaps and Voids: An Archaeometrical Study of Degraded Fibers in a Sherd From the Cueva dos Chinches Muertas, Siltzul (Raxruha, Alta Verapaz, Guatemala)

Archaeometry, EarlyView.
ABSTRACT In 2019, excavations at the Cueva dos Chinches Muertas carried out by the Raxruha Viejo Project uncovered a small ceramic sherd distinguished by a stratified structure composed of multiple layers of textile imprints, both superficial and transversal.

Modern Fire Safety Protocols in the Archeological Contexts: A New Tool for Studying the Health and Behavioral Effects of Fire Use in Semi‐Closed Spaces

Archaeometry, EarlyView.
ABSTRACT This study evaluates the application of computational fluid dynamics (CFD) simulations, integrated with controlled fire experiments, to investigate combustion processes in semi‐closed spaces. The framework enables systematic modeling of smoke dispersal, particulate transport, and hearth performance under variable morphologies and ventilation ...
