Faster and targeted raster imaging through non‐rectangular scanning

Journal of Applied Crystallography, EarlyView.
A highly efficient algorithm for raster scanning an area of non‐rectangular shapes is presented. This method can significantly reduce the required scanning time for e.g. microbeam X‐ray diffraction and X‐ray fluorescence scanning microscopy.Many materials are spatially heterogenous and it is important to characterize this heterogeneity, which can be ...

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

An Overview of the Rock Art of AlUla: Tracing Changes in Content and Form Across 12,000 Years of Human History

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Between 2018 and 2021, the Identification and Documentation of Immovable Heritage Assets (IDIHA) Project recorded over 19,000 rock art panels in the AlUla (al‐‘Ulā) region of north‐western Saudi Arabia. This study presents a chronological assessment of the corpus, drawing on superimpositions, datable motifs, inscriptions, and varnish formation,

Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

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.

Investigating the Dietary, Economic, and Social Practices of a Neolithic Funnel Beaker Community in Wanna, Germany, Through Raw Material and Organic Residue Analyses of Pottery

Archaeometry, EarlyView.
ABSTRACT This study details the analysis of an assemblage of Funnel Beaker pottery from Wanna in Northern Germany investigated using petrographic, geochemical, and organic residue analyses. The analyses revealed specialized production of pottery vessels for funerary contexts, but that domestic and funerary pottery were used intensively to process ...
