The pre-Magdalenian phase of the Côa River Valley open-air rock art is mostly distributed at the boundary between the rocky valley slopes and the floodplain that correspond to the most favourable geomorphological setting for the preservation of pecked and deeply superposed engravings of the most famous artistic phase of the area. The natural vertical panels of the engraved art located at this geomorphological interface have suffered weathering during two cold events of the Lateglacial. They were buried by several colluvial and alluvial deposits. The reconstruction of the sedimentary and archaeological context of the CôaRiver Valley engraving permits a better assessment of the preservation processes and interpretation of Palaeolithic open-air rock art. 相似文献

Climatic signal in tree-ring chronologies of Cedrus deodara from Chitral Hindukush Range of Pakistan
Tree-rings are an important tool for the investigation of paleoclimatic records for regions or periods of time with no instrumental climatic data. However, the responses of different species and sites to various climatic parameters are unusual. In the present study, we developed tree-ring-width chronologies of Cedrus deodara from three different sites of Chitral Hindukush range of Pakistan. The study was conducted to understand tree-growth climate relationship and its applicability in proxy climate investigations. The chronologies covered the past 469 to 595 years, with a mean segment length (MSL) ranging from 148 to 223 years. Climatic data obtained from the three weather stations showed strong correlation and was found useful for tree-ring climate relationships. Correlation Function (CF) and Response Function (RF) analysis showed that spring precipitation (March–May) is a critical limiting factor for tree-ring growth, and temperature prior to November may also play a major role in affecting tree ring-growth. The results exposed that the three sites have continuous relationship indicated that only single species from different locations are affected by the same environmental variables and hence can be used in climate reconstruction in combination. The Cedrus deodara chronologies developed at different locations had several corresponding narrow and wide marker rings indicating a large macroclimatic response to regional climatic conditions. The current study suggests that the tree-rings of Cedrus deodara from the Chitral Hindukush range could be used to develop chronologies for the reconstruction of seasonal climatic variables. 相似文献

Kosovo has been under various forms of international administration since 1999. Although the political dimension of this international experience has been widely studied by scholars — especially those associated with the critical theory of liberal peacebuilding — the economic dimension of international rule has received less attention. This article explores the economic dimension by linking insights from rentier theory with critical approaches to liberal peacebuilding and statebuilding. The postulate informing this article is that the sources of a state's income have an impact on its institutional development. The article discusses liberal peacebuilding through the lens of rentier theory, it analyses the economic management in the early years of the international administration of Kosovo, and describes and explores some of the unintended consequences of this massive international presence in Kosovo for the local economy. 相似文献

The potential of hyperspectral and multi-spectral imagery to enhance archaeological cropmark detection: a comparative study 总被引:1,自引:0,他引:1
Aerial photography has made the single most important contribution to our improved appreciation of the density, diversity and distribution of archaeological sites in Britain since World War Two. This is particularly the case for areas of intensive lowland agriculture where ploughed-out sites are known mainly from marks in the crops growing above them. However, reconnaissance for such cropmarks is not equally effective throughout the lowlands, because of the particular conditions of drier weather, well-drained soils and arable agriculture required before they become visible, and is highly unpredictable. 相似文献

Conservation in urban areas is an active issue, but in remoter areas historical remains are neglected by both public and government. Conservation of maritime archaeological sites is fast becoming important elsewhere. Acknowledging the importance of conservation for other types of historical sites, this paper addresses the need for conservation of the as-yet-unknown number of maritime archaeological sites in Malaysia. This will take time and continuing effort. Malacca Maritime Museum is a case-study, built specifically for showcasing artefacts from shipwrecks. The first such museum in Malaysia, it has benefited tourism as well as preserving objects and educating the public.
