Archaeometric provenance study of marbles from Porphyreon and Chhim (Lebanon) and early Byzantine production specialisation

open access: yesArchaeometry, EarlyView.
Abstract Early Byzantine marble objects from Porphyreon and Chhim (Lebanon) were studied to assess the source of raw materials. In all, 66 artefacts, including elements of liturgical furnishings, architectural elements and daily use objects, were examined using optical, cathodoluminescence and scanning electron microscopy, X‐ray diffraction, and δ13C ...

Characterisation of Jewellery with glass and garnet inlays from the Bohemian region and Great Migration Period

open access: yesArchaeometry, EarlyView.
Abstract The research focuses on jewellery finds uncovered in the region of today's Czech Republic dated to the Great Migration Period. The metals and garnet inlays detected were examined with μ‐EDXRF, whereas, for glass samples, LA‐ICP‐MS was used. The paper presented is supplemented with data concerning the technological processing of the jewellery ...

Isotopic Data on Diet and Mobility from Pictish and Viking Age Orkney

open access: yesJournal of Open Archaeology Data
Changes in diet and mobility isotopes from the Late Iron Age or Pre-Viking phase (PVP, AD 550–790) through the Viking Age (VA, AD 790–1050) and Late Norse phase (LNP, AD 1050–1300) can be used to suggest nuanced socioeconomic and political change ...

Tracking Bronze Age ‘itinerant smiths’ in western Poland: insights from Nd and Sr isotope data

open access: yesArchaeometry, EarlyView.
Abstract The neodymium (Nd) isotope composition of stone casting moulds found in graves of Bronze Age ‘itinerant smiths’ in western Poland was analysed to determine the provenance of their raw materials. For the first time in archaeological research, the Nd model age (TDM)—a highly useful parameter in studying the provenance of geological materials—has

Optical pumping of 5s4d^{1}D_{2} strontium atoms for laser cooling and imaging

open access: yesPhysical Review Research
We present a faster repumping scheme for strontium magneto-optical traps operating on the broad 5s^{2}^{1}S_{0}−5s5p^{1}P_{1} laser cooling transition. Contrary to existing repumping schemes, we directly address lost atoms that spontaneously decayed to ...

Palaeoenvironmental changes recorded at the Velika Vrbica loess‐palaeosol sequence, Wallachian Basin, during MIS 3–MIS 1

open access: yesBoreas, EarlyView.
This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χlf), and mass ...

A 3200‐year weathering record of the Mekong River basin by sediments from the South China Sea

open access: yesBoreas, EarlyView.
The Mekong River is a mega‐river in East and Southeast Asia, and precipitation in its watershed influences more than 300 million people. However, the controlling factor in precipitation and weathering in the basin remains controversial. Here we present a high‐resolution record of weathering of the Mekong River basin over the past 3200 years by ...
