Archaeometry (radiometric dating, metallography) for two early Iron-Age axes from Northern Europe and Central Asia
This study discusses the archaeometry (radiometric dating and metallography) of two Iron-Age axes, one from Kazakhstan (Kyzylzhartas Axe-Adze) and one from Northern Germany (Högersdorf Axe). To understand their age and production, 14 C dating of metallic bound carbon and metallographic analysiswere performed. The Kyzylzhartas Axe-Adze dates to 357–166 BCE and shows an advanced production technique with a careful selection of carburized and non-ca…
Carbon isotopes ( 14 C, 13 C) of Gatersleben plant tissues ( Triticum aestivum L., Glycine max (L.) Merr.) grown during the bomb spike
Here we present an updated version of radiocarbon concentrations measured in seeds from the Gatersleben Crop Plant Research institute. 14 C-isotope measurements for wheat from 1946 to 2020, which were presented previously, have been complemented with 14 C measurements made on soybean and continued until late summer 2025. Additionally, we measured δ 13 C in wheat samples. A comparison of different 14 C time series over the last 80 years from diffe…
Radiocarbon changes in the XI century CE in annual tree rings
This paper presents new radiocarbon ( 14 C) measurements from annual tree rings of English oak ( Quercus robur L.) from Kujawy, Poland, spanning 1042–1062 CE. The results confirm an increase in Δ 14 C values between 1053 and 1055 CE, within the Oort Minimum of solar activity, consistent with literature values (Brehm et al. 2021a; Eastoe et al. 2019; Terrasi et al. 2020). The data reveal a sustained increase in Δ 14 C values between 1053 and 1055 …
Physiological reactions in plants visualized by 14C
Marine aerosols can enter the terrestrial environment via sea spray which is known to affect the stable isotope fingerprint of coastal samples (plants, animals/humans), including δ 13 C. However, the impact of sea spray on 14 C dating of terrestrial organisms at coastal sites has not been investigated so far. Besides a direct effect, sea spray is accompanied by physiological effects, e.g., due to salinity. In an artificial sea spray experiment in…
First results of metallographic analysis and absolute dating of iron finds from Nowe Brzesko, site 26, Proszowice District
This paper presents the results of analyses of metal artefacts discovered at a multiphase site in Nowe Brzesko, Małopolskie Voivodeship, Poland. Fieldwalking prospection led to the discovery of steely iron objects, ploughed out on the site among other numerous archeological finds. A prospecting sondage yielded more corroded metal artefacts, identified mainly as agricultural tools (e.g. sickles, scythes). These chronologically nondistinctive artef…
The Miyake Event in 993 Ce Recorded in Oak Sub-Annual Tree Rings From Kujawy (Poland)
This article presents measurements of the radiocarbon ( 14 C) concentration in sub-annual tree rings. Samples of earlywood (EW) and latewood (LW) from dendrochronologically dated tree rings (English oak, Quercus robur ) from Kujawy, near Kraków (Poland), spanning the years of 990–997 CE, are extracted and their 14 C content is measured at the Center for Applied Isotope Studies at the University of Georgia, USA. The EW and LW data show a gradual i…
Wheat Seed ( Triticum Aestivum L.) Radiocarbon Concentration Over the Last 75 Years
Here we report radiocarbon measurements made on wheat seed tissue ( Triticum aestivum L.; winter or spring type growth habit), from the seed archive of the IPK Gatersleben, Sachsen-Anhalt, Germany, which was harvested between 1946 and 2020. The results give an overview of 75 years of radiocarbon concentration evolution in agricultural plant products. The wheat tissue radiocarbon concentrations follow known pre- and post-bomb radiocarbon records, …
Interpreting 14 C Measurements on 3rd–4th Century AD Iron Artifacts from Nydam, Denmark
Radiocarbon ( 14 C) ages were determined for 10 iron samples from the war booty offering site in the Nydam peat bog (SE Denmark), and compared to archaeologically inferred periods of deposition. Additional 14 C measurements were carried out for modern iron standards made with charcoal of known isotopic composition to evaluate possible effects of handling. Modern iron standards give depleted 14 C concentrations, compared to the initial charcoal 14…
Absolute Dating of Early Iron Objects from the Ancient Orient
Luristan Iron Mask Swords have been recovered mostly from illegal diggings in the 1920s. The about 90 known objects are characterized by a disk-shaped pommel on the top of the handle with two mounted bearded heads on two sides. According to the similarity in form and radiocarbon ( 14 C) measurements on two swords from museum collections, an overall short production period was assumed around 1000 BC (Moorey 1991; Rehder 1991). Here we present the …
Abrupt Increase of Radiocarbon Concentration in 660 BC in Tree Rings from Grabie Near Kraków (SE Poland)
Miyake et al. (2012, 2013, 2014) described a sudden increase of radiocarbon ( 14 C) concentration in annual tree rings of Japanese cedar ( Cryptomeria japonica ) and Hinoki cypress ( Chamaecyparis obtusa) between AD 774 and 775 and between AD 993 and 994. In both analyzed periods, the sudden increase was observed almost in a single year. The increase in the 14 C content was about 12‰ in the period AD 774–775 (Miyake et al. 2012) and about 11.3‰ i…
Radiocarbon Dating Cremated Bone
Radiocarbon ( 14 C) results on cremated bone are frequently published in high-ranking journals, but 14 C laboratories employ different pretreatment methods as they have divergent perceptions of what sources of contaminants might be present. We found pretreatment protocols to vary significantly between three laboratories (Brussels [RICH], Kiel [KIA], and Groningen [CIO]), which all have a long history of dating cremated bone. We present a case stu…
A New Graphitization System for Radiocarbon Dating with AMS in the Dendrochronological Laboratory at AGH-UST Kraków
A new vacuum system for the preparation of graphite samples for radiocarbon ( 14 C) measurement using an accelerator mass spectrometer (AMS) was constructed at the Dendrochronological Laboratory in AGH-UST Kraków. The central part of the system is a manual vacuum line for the production of graphite from carbon dioxide for subsequent AMS measurements. The graphitization system can handle up to five samples simultaneously, and the process lasts for…
Increase in Radiocarbon Concentration in Tree Rings from Kujawy Village (Se Poland) Around Ad 993–994
An increase in atmospheric radiocarbon ( 14 C) content of about 11.3‰ in the period AD 993–994 was observed in annual tree rings from Japanese cedar ( Cryptomeria japonica ) and Hinoki cypress ( Chamaecyparis obtusa) (Miyake et al. 2013, 2014). Single-year samples of dendrochronologically dated tree rings (English oak, Quercus robur ) from Kujawy, a village near Krakow (SE Poland), spanning the years AD 981–1000, were collected, and their 14 C co…
Laboratory Intercomparison of Pleistocene Bone Radiocarbon Dating Protocols
Since its invention in the late 1940s, radiocarbon ( 14 C) dating has become an important tool for absolute dating. A prerequisite for the acceptance of this method is consistency between, and compatibility of, 14 C dates from different laboratories. To meet these requirements, international laboratory intercomparison studies with different sample materials are frequently performed (e.g. TIRI, FIRI, VIRI and, most recently, SIRI).Intercomparison …
