New evidence for Bronze Age agricultural settlements in the Zhunge’er (Junggar) Basin, China

Abstract The Zhunge’er (Junggar) Basin in northern Xinjiang was a key crossroads in antiquity for the dispersal of ideas and technological innovations from the Eurasian steppe into the heartland of central China. The Bronze Age chronology of the Zhunge’er Basin is chiefly based on relative dating and little is known about subsistence strategies, although the strong tradition of nomadic and transhumant pastoralism among modern populations suggests that there may have been a high degree of mobility. The visibility of ancient cemeteries and the need to salvage graves before they are looted have resulted in a lack of focus on settlements, with a consequent assumption that in antiquity agriculture played a limited role. This assumption has been challenged by rescue excavations at the Jimusa’er (Jimsar) Luanzagangzi site, which indicate that agriculture may have been a significant component of Bronze Age subsistence strategies. Small-scale soundings at settlement sites provide well-stratified sequences of material for absolute dating which can be used to place the artifacts recovered from graves in a more secure chronological context.

Adunqiaolu: new evidence for the Andronovo in Xinjiang, China

Abstract Bronze Age social and cultural interconnections across the Eurasian steppe are the subject of much current debate. A particularly significant place is occupied by the Andronovo Culture or family of cultures. Important new data document the most easterly extension of Eurasian Bronze Age sites of Andronovo affinity into western China. Findings from the site of Adunqiaolu in Xinjiang and a new series of radiocarbon dates challenge existing models of eastward cultural dispersion, and demonstrate the need to reconsider the older chronologies and migration theories. The site is well preserved and offers robust potential for deeper study of the Andronovo culture complex, particularly in the eastern mountain regions.

Wood types and human impact between 4300 and 2400 yr BP in the Hexi Corridor, NW China, inferred from charcoal records

Based on identification of fossil charcoals from 11 sites in the Hexi Corridor, we reconstruct the local vegetation community and human impact on it in the period from 4300 to 2400 cal. yr BP. More than 20 broadleaved taxa and 4 coniferous trees are present. The charcoal identifications show that vegetation in the period 4300–2400 cal. yr BP differed regionally because of variations in local topography and water supply, with limited diversity in the northwest Hexi Corridor and relatively rich diversity in the southeast area. In the northwest Hexi Corridor, the oasis woodland consisted mainly of Tamarix sp., Salix sp., and Populus sp. In the southeast region, the vegetation was a mix of coniferous forest and broadleaf woodland. By comparison with modern patterns of vegetation, broadleaf trees were much more abundant and the spruce forest extended down to relatively low altitudes, suggesting greater vegetation cover and richer diversity than today. There was also temporal variation. In the period from 4300 to 4000 cal. yr BP, woodland was relatively scarce, while the greatest diversity of plants appears in the period from 4000 to 3500 cal. yr BP, probably because of better moisture conditions at that time. After 3500 cal. yr BP, there was the appearance of woodland dominated by Morus alba, suggesting that cultivated trees may have played a key role in the lives of local people.

REMAINS OF A PUZZLE: THE DISTRIBUTION OF VOLCANIC GLASS ARTIFACTS FROM SOURCES IN NORTHEAST CHINA AND FAR EAST RUSSIA

Abstract Previous geochemical studies of volcanic glass artifacts dating to the Late Palaeolithic in northeast Asia have revealed a wide distribution of artifacts from sources in China, Korea, and Far East Russia. Through an analysis of lithic technology, this study sheds new light on the variety and complexity of the social, technological, and landscape factors that shaped the long distance movement of stone artifacts.

Commentary: A Critical Review of Environmental Archaeology in Northeast China

Environmental archaeology in northeastern China has reached a critical period of development, although the state of progress varies across this large geographical region. The lack of collaboration between archaeologists and associated scientists remains the main obstacle in current research. Almost exclusively conducted by dedicated scientists, research in the field is often ignored by archaeologists because it is not presented within an archaeological context. Furthermore, the research is not of a high spatial and temporal resolution: there is the tendency to make broad generalizations about large regions over long periods of time and to disregard areas that do not fit their general climatic models. Another problem is the misguided borrowing of concepts developed in other parts of the world, for example, the Holocene Climate Optimum (HCO), which is well defined in prehistoric Europe but is still being developed in China. Many researchers have simply applied this term to the same period in China and assumed that the climate around that period resembled that of prehistoric Europe, despite the fact that this is currently unsupported by local palaeo-environmental evidence. Other obstacles to the development of environmental archaeology include deterministic approaches and oversimplistic research procedures. To address these problems, a conversion of qualitative data to quantitative data on temperature and precipitation is required. Future research should be conducted by teams of scientists and archaeologists working collaboratively on both natural and archaeological deposits, in order to establish a strong foundation for further environmental reconstruction research.
