Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

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.

Tracing Identity in a Fragmented Past: Multi‐Proxy Analysis of Human Skeletal Remains From Dungowan Creek, New South Wales, Australia

Archaeometry, EarlyView.
ABSTRACT Human skeletal remains constitute critical archaeological evidence for reconstructing past societies, yet their investigation requires careful ethical, cultural, and legislative consideration. This paper reports on the discovery, recovery and analysis of a set of skeletal remains encountered during a cultural heritage management (CHM ...

Materials Characterization and Technological Aspects of Hellenistic Grey Ware Lamps From Nysa‐Scythopolis (Israel): Evidence Suggesting Local Production?

Archaeometry, EarlyView.
ABSTRACT Grey ware lamp fragments and a production waster from Tell Iẓṭabba (Israel) were analyzed to determine their manufacturing technology and provenance. These were compared with a light brown‐orange reference fabric from the same site.

Talc‐Tempered Pottery From Bala Hissar, Kabul: An Analytical Study

Archaeometry, EarlyView.
ABSTRACT Potsherds of cooking ware excavated at Bala Hissar archaeological site in Kabul were studied using X‐ray fluorescence (XRF), scanning electron microscope‐energy dispersive X‐ray spectrometry (SEM‐EDS), Raman spectroscopy, X‐ray powder diffraction (XRPD), thermogravimetric analysis (TGA) and optical microscopy.

An Experimental Approach on Pearl Shell (Pinctada margaritifera) for a Microwear Study of Shell Artefacts From French Polynesia

Archaeometry, EarlyView.
ABSTRACT Pinctada margaritifera (black‐lipped pearl oyster) artefacts are ubiquitous in the archaeological record throughout the Pacific and particularly in Polynesia. Despite efforts towards the development of typologies, the lack of microwear and use‐wear studies has prevented the development of technological approaches. We used 20 pearl shell valves

Exploring Use‐Wear Texture Quantification Through Confocal Microscopy on Tools Made From Volcanic Rocks (Basalt and Phonolite)

Archaeometry, EarlyView.
ABSTRACT Functional analysis is essential for reconstructing lithic tool use. Recent approaches combining confocal microscopy and surface texture analysis provide quantitative alternatives to traditional visual use‐wear analysis, although their application to coarse‐grained, heterogeneous rocks remains challenging because of their complex surface ...

Lithostratigraphy, geology and geochemistry of the volcanic rocks of the Maligât Formation and associated intrusions on Disko and Nuussuaq, Paleocene of West Greenland

Geological Survey of Denmark and Greenland Bulletin, 2018
The Paleocene volcanic rocks in the Nuussuaq Basin on Disko and Nuussuaq comprise the picritic Vaigat Formation (c. 62–61 Ma) and the overlying basaltic Maligât Formation (c. 60 Ma).

Influence of Laser Repetition Rate, Fluence and Spot Size on LA‐Q‐ICP‐MS/MS 87Sr/86Sr Precision: Insights from Apatites and Silicate Glasses

Geostandards and Geoanalytical Research, EarlyView.
Key Points Higher laser repetition rate, fluence and larger spot size increase signal intensity. Higher laser repetition rate produces overlaps in aerosolised particles, improving signal stability and precision. For Sr‐rich materials, moderate spot diameter (≤ 60 μm), 3 J cm‐2 fluence and ≥ 12 Hz repetition rate are recommended.

Quantification of Sulfur Speciation in Apatites: Comparison of the XAS, XPS and EPMA Techniques

Geostandards and Geoanalytical Research, EarlyView.
Key Points Sulfur speciation in apatites has been determined by S K‐edge X‐ray absorption near‐edge structure (XANES) spectroscopy, S 2p X‐ray photoelectron spectroscopy (XPS) and electron probe microanalysis (EPMA). XANES provides the most sensitive and accurate quantification of sulfur speciation.
