The study explores the origins and evolution of the Late Krotovo (Cherno-Ozerye) – a Middle Bronze Age culture in the Irtysh drainage. The Late Krotovo culture emerged in the late 3rd – early 2nd millennium BC in the Baraba forest-steppe as the final stage of the Krotovo culture proper. The people associated with the Late Krotovo were natives influenced, first indirectly and then directly, by the Andronovo (Fedorovka) tribes. The Andronovo impact is mirrored by the material culture, burial rites, decorative art, and paleogenetics. The outcome of the interaction constitutes a new archaeological phenomenon, represented by sites such as Cherno-Ozerye-1 and Tartas-1.  相似文献

New work at Kehf el Hammar Cave provides the first well-dated palaeoenvironmental sequence for the Late Upper Palaeolithic in this region of the northwest Maghreb. The archaeological layers are dated via a combination of AMS radiocarbon and luminescence dating methods. The sequence contains charcoal-rich occupation layers with faunal, human and lithic finds. Local vegetational patterns are reconstructed on the basis of preliminary analysis of the charcoal evidence. Using standard calibration curves the AMS radiocarbon dates are compared with proxy evidence for climatic change from sea core records in the Alborán Sea. These appear to show that the Late Upper Palaeolithic occupation of the region coincides closely with Heinrich Event 1, a period marked by intense aridification and dating to ca. 16,700–17,250 calendar years ago.Les nouvelles recherches dans la grotte de Kehf el Hammar ont permis d’obtenir la première séquence paléoenevironnementale bien datée du Paléolithique supérieur tardif au Nord Ouest du Maghreb. En effet, les niveaux archéologiques ont été datés par le radiocarbone par accélérateur (AMS) et des méthodes radiométriques basées sur la luminescence. En revanche, les paléoenvironnements végétaux ont été partiellement reconstitués à base des premières analyses des charbons de bois. Les dates AMS calibrées ont été comparées aux données climatiques issues des carottes marines dans la mer Alborán. Ainsi, les occupations humaines du Paléolithique supérieur tardif dans la région ont sensiblement coïncidé avec l’événement climatique Heinrich 1. Celui-ci correspond à une période qui a été marquée par une aridification intense entre 16.700 et 17.250 ans (cal.).  相似文献

The Ramat Saharonim site, located in the central Negev desert, Israel, consists of four shrines in a shallow valley and 30 tumuli, aligned on two cuesta cliffs on the valley's sides. Previous assessments based on site surveys suggested a general chronological span from Late Neolithic period (ca. 5000–5500 BC) through the Early Bronze Age (third millennium BC). Excavations in one shrine and three tumuli revealed a well-constructed double wall at the shrine and seven primary adult burials in the three tumuli. Quartz from sediment samples post-dating the construction of the burials and shrine was dated by optically stimulated luminescence (OSL) using the single aliquot regenerative dose (SAR) protocol, and charcoal and leather samples were dated by 14C. The OSL results for a burial in one tumulus are 7500 ± 700 to 6000 ± 600 years. In a second tumulus, OSL ages of 2000 ± 200–1800 ± 170 years and a 14C age on leather of 390–200 BC (2340–2150 cal BP) imply that this burial is Nabatean and that the site was used also in the Hellenistic period. Two 14C ages on charcoal from the shrine give an age between 5280 and 4710 BC (7230–6660 cal BP). OSL single aliquot ages for sediment from the shrine are highly scattered and far too old (60,000 to 12,000 years). The unlikely old ages are due to insufficient resetting of the OSL signal of some of the quartz grains when sand was blown onto the site. Indeed, single grain measurements for six samples of sediment postdating the shrine show a very large range of grain ages, but with a distinct young population in all samples. Ages calculated from these young populations average 5400 ± 800, in better consistence with the 14C dates and confirming our supposition that only some of the transported grains were reset at the time of deposition. The combined OSL and 14C dating shows that the shrines and tumuli are contemporaneous and attributes the complex to the Late Neolithic. This has clear ramifications for our understanding of the period and the rise of desert pastoral societies.  相似文献

Utilising recent observations by Phillips (2003) on the location of chambered cairns in Orkney in relation to the sea this paper attempts to explain why megalithic monuments cluster in particular locations. In the past, the distribution of cairns has been related to the levels of survival in marginal locations. However, monument locations, from across Scotland, demonstrate that clustering was a feature of monumental distribution in the past. From a maritime perspective it becomes easier to understand these groupings in Orkney as the product of interactions between widely dispersed island communities. Utilising a long-term perspective it is possible to use the relative patterning of monuments of different ages to suggest the changing audiences to whom these monuments were addressed. For example, the clustering of Earlier Neolithic monuments in Orkney, in places that form important linking locales, suggests a role for these monuments involving establishing and maintaining links between island groups within the Orkney archipelago. The location of later Neolithic monumental complexes, on the other hand, suggests the importance of inter-regional maritime contact at precisely the time when such contacts are strikingly evident in the archaeological record. It is argued that a closer integration of our approaches to land and sea is needed if we are to understand the nature of long distance contacts in the past.

晚清留英教育在船政学生留英之前已经开始,同治五年(1866年),清政府就派遣了同文馆学生赴欧洲游学。之后,历届驻英公使都带有同文馆学生充任使馆随员或翻译学生,在处理外交及使馆事务之外,这些同文馆学生还负有学习的任务,可以入英国学校学习。19世纪90年代总理衙门还制订章程,派遣了两次同文馆留英生。20世纪初,京师同文馆归并京师大学堂改称译学馆后,再次派遣学生赴英留学。同文馆学生留英在整个晚清虽然不多,但也自成一系,是晚清留英教育中重要的一支。  相似文献
