Varved lake sediments from Lake Zabihskie (northeastern Poland) provide a high- resolution calendar-year chronology which allows validation of 14C dating results. Microscopic analysis of the varve microfacies revealed that laminations found in Lake Zabihskie were biogenic (calcite) varves. Three independent counts indicated a good preservation quality of laminae in the 348 cm long sediment profile which contained 1000+12/-24 varves. The varve chronology was validated with the 137Cs activity peaks, the tephra horizon from the Askja eruption at AD 1875 and with the timing of major land-use changes of known age inferred from pollen analysis. 32 AMS 14C dates of terrestrial macrofossils distributed along the profile were compared with the varve chronology. After identification of outliers, the free-shape model performed with 21 14C dates provided the best possible fit with the varve chronology. We observed almost ideal consistency between both chronologies from the present until AD 1250 while in the lower part (AD 1000-1250) the difference increases to ca. 25 years. We demonstrate that this offset can be explained by too old radiocarbon ages of plant remains transported to the lake by the inflowing creek. Results of this study highlight that careful interpretation of radiocarbon age-depth models is necessary, especially in lakes where no annual laminations are observed and no independent method are used for cross-validation.
The paper presents δ13C and δ15N isotope content measurements in human bones from 16 graves, being part of the Yampil Barrow Complex. From the results, conclusions may be drawn about the diet of barrow builders and users. It was based on vegetable foodstuffs and characterised by a varied share of terrestrial animal meat, depending on the period. High δ13C values suggest a share of C4-type plants in the diet, possibly millet.
A set of sources embodied by features 1149A and 1149B at Święte 11, Jarosław District, Podkarpackie Province, is one of a kind in Lesser Poland as it includes a vessel associated with steppe cultures of the Northwest Black Sea Coast. The vessel has been discovered in a stratigraphic context that is not fully clear. It probably constituted an offering (trizna) connected with the male burial identified in the niche grave underneath. The vessel appears to be linked to the late Yamnaya/early Catacomb horizon. Such chronological attribution is further supported by an absolute date of the 2nd half of the third millennium BC established for bones. The vessel sits alongside other finds that provide corroboration for connections the population of the younger Corded Ware phase in Lesser Poland had with eastern European regions.
The paper discusses the 2010-2015 studies of the radiocarbon chronology of Podolia ‘barrow cultures’ on the left bank of the middle Dniester. The studies have relied on series of 14C dates for the Klembivka 1, Pidlisivka 1, Porohy 3A and Prydnistryanske 1 sites determined in Kyiv and Poznań laboratories. They are the first attempt to construct a regional (‘Yampil’) radiocarbon scale for ‘Early Bronze’ funerary rites (4th/3rd-2nd millennium BC) as practised by barrow builders - the communities of the Tripolye and Yamnaya cultures - and the secondary barrow users - the designers of necropolises located on barrows - belonging to the Catacomb, Babyno and Noua cultures.
