Для оценки мобильности и идентификации происхождения древних популяций требуется проводить сравнение их изотопных отношений 87Sr/86Sr с локальной базовой (фоновой) линией биодоступного стронция, характерной для каждого конкретного местонахождения или потенциального района происхождения индивида или артефакта. В данной работе на примере древнего рудника Новотемирский (Южный Урал) эпохи бронзы проведена оценка такой базовой линии. Изотопные отношения 87Sr/86Sr определены в поверхностной и подземной воде, коренной породе (серпентинит), глине из стенки шахты, кости светлого хоря, а также в траве и раковине двустворки с берега озера. Наименьшим разбросом изотопных отношений стронция друг относительно друга обладают поверхностная и подземная вода, раковина и трава, что позволяет использовать их для определения объединенной базовой линии биодоступного стронция. Мульти-прокси (поверхностная и подземная вода, травы и раковина двустворки) локальная базовая линия биодоступного стронция для района древнего рудника Новотемирский (Южный Урал) может быть представлена в виде диапазона 0,7096 ± 0,0003 (2σ, n = 5). To assess the mobility and provenance of ancient populations, it is necessary to compare their 87Sr/86Sr isotopic ratios with the local bioavailable strontium baseline (background), characteristic of each specific location or potential provenance region of an individual or artifact. Its definition requires a comprehensive approach to the analysis of heterogeneous samples («proxies») characterizing the ecosystem of the archaeological site under study, the identification of the most suitable proxies, as well as the unification and standardization of the sampling and analytic protocols. A pilot study is presented devoted the definition of the local range of bioavailable strontium by the example of the Novotemirskiy Bronze Age mine (Southern Urals). 87Sr/86Sr isotope ratios were determined in surface and underground water, bedrock (serpentinite), clay from the mine wall, and steppe polecat's bone, as well as in grass and a bivalve shell from the lake. The lowest range of strontium isotope ratios relative to each other is characteristic of surface and groundwater, shell and grass, which allows them to be used to determine the combined baseline of bioavailable strontium. Multi-proxy (surface and underground water, grass and a bivalve shell) local bioavailable strontium baseline for the Novotemirskiy ancient mine (Southern Urals) is 0,7096 ± 0,0003 (2σ, n = 5).

Strontium Isotope Ratios

Abstract Strontium isotope ratios (87Sr/86Sr) were applied to investigate provenance amongst the Final Eneolithic population at Święte (sites 11, 15 and 20) in the Subcarpathian region, south-eastern Poland. The study used 11 human enamel samples collected from the niche graves of the Corded Ware culture. To obtain base-line information on the local Sr isotope composition seven animal enamel samples were also examined. They were found in the adjacent archaeological sites of the Mierzanowice culture at Mirocin and Dobkowice, which have the same environmental and geological background as the sites at Święte. The investigated individuals from Święte display a wide spectrum of Sr isotope signatures, from 0.7094 to 0.7109. Because a comparison of human 87Sr/86Sr values from Święte with Sr animal signatures from Early Bronze Age sites in the area is not unambiguous the local range of 87Sr/86Sr values were based on published data for the Subcarpathian population of the Corded Ware culture. Strontium isotope ratios indicate that only three males with the most radiogenic 87Sr/86Sr values exhibit local signatures. Values below 0.7103 document individuals born outside of the Subcarpathian region. Among these are all women and children, two males and one individual with undetermined sex. The probable homeland of the non-local individuals were areas along the northern and eastern margins of the Carpathian Foredeep in Poland and Ukraine.

The recovery of inaperturate pollen from functionally female flowers in archaeological layers opens the question of a possible pollen-based discrimination between wild and domesticated Vitis vinifera in prehistoric times. Pollen analysis applied to archaeology has not routinely considered the existence of pollen dimorphism in Vitis, a well-known trait in the field of agrarian studies. Therefore, the inaperturate shape of grapevine pollen is ignored by studies on the archaeobotanical history of viticulture. In this paper we investigate pollen morphology of the domesticated and wild subspecies of V. vinifera, and report the first evidence of inaperturate Vitis pollen from an archaeological site. We studied exemplar cases of plants with hermaphroditic flowers, belonging to the subspecies vinifera with fully developed male and female organs, cases of dioecious plants with male or female flowers, belonging to the wild subspecies sylvestris and cases of V. vinifera subsp. vinifera with morphologically hermaphroditic but functionally female flowers. The pollen produced by hermaphroditic and male flowers is usually trizonocolporate; the pollen produced by female flowers is inaperturate. This paper reports on the inaperturate pollen of Vitis found in an archeological site of the Po Plain, Northern Italy. The site dated to the Bronze Age, which is known to have been a critical age for the use of this plant with a transition from wild to domesticated Vitis in central Mediterranean. Can the inaperturate Vitis pollen be a marker of wild Vitis vinifera in prehistoric times? Palynology suggests a possible new investigation strategy on the ancient history of the wild and cultivated grapevine. The pollen dimorphism also implies a different production and dispersal of pollen of the wild and the domesticated subspecies. Grapevine plants are palynologically different from the other Mediterranean “cultural trees”. In fact, Olea, Juglans and Castanea, which are included in the OJC index, have the same pollen morphology and the same pollen dispersal, in wild and domesticated plants. In contrast, the signal of Vitis pollen in past records may be different depending on the hermaphroditic or dioecious subspecies.

Thera Eruption

The Late Bronze Age Thera eruption was one of the largest natural disasters witnessed in human history. Its impact, consequences, and timing have dominated the discourse of ancient Mediterranean studies for nearly a century. Despite the eruption’s high intensity (Volcanic Explosivity Index 7; Dense Rock Equivalent of 78 to 86 km) [T. H. Druitt, F. W. McCoy, G. E. Vougioukalakis, Elements 15, 185–190 (2019)] and tsunami-generating capabilities [K. Minoura et al., Geology 28, 59–62 (2000)], few tsunami deposits are reported. In contrast, descriptions of pumice, ash, and tephra deposits are widely published. This mismatch may be an artifact of interpretive capabilities, given how rapidly tsunami sedimentology has advanced in recent years. A well-preserved volcanic ash layer and chaotic destruction horizon were identified in stratified deposits at Çeşme-Bağlararası, a western Anatolian/Aegean coastal archaeological site. To interpret these deposits, archaeological and sedimentological analysis (X-ray fluorescence spectroscopy instrumental neutron activation analysis, granulometry, micropaleontology, and radiocarbon dating) were performed. According to the results, the archaeological site was hit by a series of strong tsunamis that caused damage and erosion, leaving behind a thick layer of debris, distinguishable by its physical, biological, and chemical signature. An articulated human and dog skeleton discovered within the tsunami debris are in situ victims related to the Late Bronze Age Thera eruption event. Calibrated radiocarbon ages from well-constrained, short-lived organics from within the tsunami deposit constrain the event to no earlier than 1612 BCE. The deposit provides a time capsule that demonstrates the nature, enormity, and expansive geographic extent of this catastrophic event.

AbstractMore than 50 years of archaeological survey work carried out in Cappadocia in central Turkey has produced a number of important contributions to the understanding of long-term settlement histories. This article synthesises and critically evaluates the results of three field surveys conducted in Cappadocia which recorded material remains dating from the Early Holocene through to the establishment of the Republic of Turkey. Results from the combined Cappadocia surveys reveal temporal patterns over the longue durée that include a lack of detectable pre-Neolithic occupation and important exploitation of obsidian as a raw material during the Neolithic. There was growth and expansion of settlement during the later Chalcolithic and Early Bronze Age, a steady continuation of settlement during the Middle and Late Bronze Ages, followed by rupture in settlement at the end of the Bronze Age. A new phase of settlement expansion began during the Iron Age and continued through Hellenistic and Roman times. This in turn was disrupted during the Byzantine period, which is associated with increased numbers of fortified sites. The succeeding long cycle of settlement began in Seljuk times and continued through to the end of the Ottoman period. Comparison with systematic archaeological site surveys in the adjacent regions of Paphlagonia and Konya shows some differences in settlement patterns, but overall broad sim¬ilarities indicate a coherent trajectory of settlement across central Anatolia over the last ten millennia.
