Overview of pretreatment protocols and 14 C measurement quality with AMS facilities (SSAMS and LEA) at the Accelerator Mass Spectrometry Laboratory, Lithuania
Open AccessJustina Šapolaitė, Laima Kazakevičiūtė-Jakučiūnienė et al.ARTICLERadiocarbon2025Cited by: 1
This study from the Accelerator Mass Spectrometry Laboratory at the Center for Physical Sciences and Technology (FTMC), Vilnius, Lithuania, presents a detailed description of the sample preparation methods employed in the laboratory, with a focus on two AMS systems: a single-stage accelerator mass spectrometer (SSAMS) and a low energy accelerator (LEA). A pivotal aspect of this article is our participation in the GIRI intercomparison test, demons…
Plants in the artefacts not used for their original purpose. A remarkable case from the Lazdininkai (Kalnalaukis) cemetery in western Lithuania
Open AccessAudronė Bliujienė, Dalia Kisielienė et al.ARTICLEArchaeologia BALTICA2023
This article investigates tinned bronze ornaments found in two graves of the Lazdininkai-Kalnalaukis cemetery dated to the end of the 2nd century to the first quarter of the 3rd century AD from the perspective of archaeological materials, intercultural contacts, 14C AMS dating, and chemical-physical and biological research. These ornaments — a wheel-shaped pendant and a bead — were originally parts of fashionable necklaces. However, these ornamen…
New insights into the subsistence economy of the Late Bronze Age (1100–400 cal BC) communities in the southeastern Baltic
Open AccessKarolis Minkevičius, Giedrė Piličiauskienė et al.ARTICLEArchaeologia BALTICA2023
This paper presents the findings of a research project aimed at reconstructing the subsistence economy of the Late Bronze Age communities in eastern Lithuania. We focused on examining archaeobotanical and zooarchaeological assemblages from three hillforts alongside δ13C and δ15N stable isotope analysis of plant and animal remains. Our results suggest that local populations primarily relied on growing domestic plants and animals for their subsiste…

New Human Bone Radiocarbon Dates From the Roman Period–migration Period Lithuanian Cemeteries
Open AccessLaurynas Kurila, Giedrė Piličiauskienė et al.ARTICLERadiocarbon2023Cited by: 2References: 14
A set (n = 37) of new human bone radiocarbon accelerator mass spectrometry ( 14 C AMS) dates from 11 Lithuanian Late Roman Period–Migration Period cemeteries is presented and discussed in the light of the established schemes of archaeological chronology. The focus of the paper is on the burials of the military and social elite, which indicate the emergence of new cultural traditions in E–S and W–Central Lithuania or the immigration that took plac…
Analysis of Radiocarbon Distribution in the Eutrophic Lake Fish Assemblage Using Stable C, N, S Isotopes
Open AccessRūta Barisevičiūtė, Vytautas Rakauskas et al.ARTICLERadiocarbon2023References: 37
The carbon isotope distribution and its relationship with stable N and S isotope ratio values were investigated within a fish assemblage from the shallow lake Tapeliai, which is constantly affected by inflows of 14 C depleted water from the surrounding watershed mires. The “conventional” radiocarbon age within the fish from this lake varied from 119 to 693 yr. The 14 C/ 12 C and δ 13 C values correlated significantly (r=0.85 p 14 C/ 12 C values a…
Horses in Lithuania in the Late Roman–Medieval Period (3rd–14th C AD) Burial Sites
Open AccessGiedrė Piličiauskienė, Laurynas Kurila et al.ARTICLEAnimals2022
The tradition of burying horses in Lithuania lasted from the Early Roman period until the late 14th C AD. It was the longest-lasting custom in Europe, which has left about 2000 known horse burials. This paper publishes the osteometric data and age of horses found in Lithuanian cemeteries and castles of the 3rd–14th C AD, over 200 individuals in total. These are the remains of all the horses still stored in Lithuanian institutions. The paper discu…

Vestiges of the Huns? The Radiocarbon-Based Chronology of the Trilobate Arrowheads from Plinkaigalis Cemetery, Central Lithuania
Laurynas Kurila, Giedrė Piličiauskienė et al.ARTICLEActa Archaeologica2021Cited by: 3
Until presently, over 60 trilobate arrowheads characteristic of Asian nomads have been found in Lithuanian hillforts or their adjacent settlements, some of them in destruction layers. These finds encouraged Lithuanian archaeologists to create a narrative about the Huns severely raiding into the region in the 5th century AD . However, it is accepted as an axiom rather than a topic for research due to the lack of precise chronology. From the Plinka…
Manufacture of the Well-Known Central and Northeastern European Eye Fibulae
Open AccessAudronė Bliujienė, Kęstutis Peseckas et al.ARTICLERadiocarbon2021References: 17
The emergence and widespread distribution of eye fibulae as adornment objects, from the northern provinces of the Roman Empire to northeastern Europe and Scandinavia, as well as their typology have been widely explored. Currently in Lithuania, a total of 209 eye fibulae dating to the 1st and 2nd centuries are known. The geographical distribution, typology and chronology of these Early Roman Period jewelry artifacts do not present any problem. How…

Mesolithic AMS 14C Evidence on Microlithic and Pressure Blade Technology in the Lakeland of Eastern Lithuania
Tomas Rimkus, Žilvinas Ežerinskis et al.ARTICLELithic Technology2020Cited by: 1References: 20
The paper presents directly dated evidence of microlithic and blade pressure technology from the newly discovered Žingiai Stone Age site situated in eastern Lithuania. During its extensive excavations in 2017–2018, numerous features containing typologically discerned lithic material and datable organic were uncovered. One feature, in particular, No. 11, contained preserved fragments of animal bones and wood charcoal. Its lithic inventory consiste…
The Last Swiderians in Lithuania
Open AccessGabrielė Gudaitienė, Justina Šapolaitė et al.ARTICLEArchaeologia BALTICA2019
This paper focuses on an issue that was, and still remains, unsolved in Baltic Stone Age archaeology: the dating of the very end of the period of Swiderian culture. This time, the questions raised are what cultural unit (or units) should be considered as the last Swiderians, and who were the last tanged point users in general? In addition, the latest AMS 14C dates from the Mesolithic Pabartoniai 1 site in central Lithuania are taken into consider…
Assessment of the Contamination by 14 C Airborne Releases in the Vicinity of the Ignalina Nuclear Power Plant
Open AccessAlgirdas Pabedinskas, Evaldas Maceika et al.ARTICLERadiocarbon2019Cited by: 1References: 22
A radiocarbon ( 14 C) activity analysis in the tree rings around Ignalina nuclear power plant (INPP) has been carried out with the aim to test the hypothesis to use 14 C tree-ring analysis data as a tool for the reconstruction of gaseous releases from NPP to the environment. The INPP has been in decommissioning state since the end of 2009. Tree-ring samples for 14 C analysis were collected 7 yr after final power unit shutdown from the INPP vicini…
Tracing Carbon Isotope Variations in Lake Sediments Caused by Environmental Factors During the Past Century
Open AccessRūta Barisevičiūtė, Evaldas Maceika et al.ARTICLERadiocarbon2019Cited by: 1References: 64
In this study, we examined how land use and urbanization changes in adjacent areas affected biological productivity and carbon cycling in a lake ecosystem over 100 years and how these changes are reflected in carbon isotope variations. We performed radiocarbon ( 14 C) activity and stable carbon isotope ratio analysis in two organic fractions: humin and humic acids of lake sediment. Additionally, we performed pigment and diatom analysis and determ…

Annual Variations of 14 C Concentration in the Tree Rings in the Vicinity of Ignalina Nuclear Power Plant
Open AccessŽilvinas Ežerinskis, Justina Šapolaitė et al.ARTICLERadiocarbon2018Cited by: 9References: 27
In this paper we analyze the radiocarbon ( 14 C) concentration changes over the whole operational period of the Ignalina Nuclear Power Plant (INPP) including the post-shutdown decommissioning. Environmental samples from the vicinity of the INPP and a rural area as background of pine tree rings were analyzed with the single stage accelerator mass spectrometer (SSAMS). The analysis shows the local influence of the INPP from 3 to 7 pMC. The whole ti…
