Esquilleu cave site has provided a moderately well preserved archaeological cave deposit from the Late Pleistocene in the Cantabrian area. Phytolith quantification, identification and determination of the refractive index have been carried out, together with FTIR analyses, from sediment samples collected in the profile. The comparison of the data obtained with the previous micromorphological results allows us to make inferences about the site formation processes and the Neanderthals use of the cave. Phytolith results show the presence of grass leaves nearby the hearth suggesting the repetitive existence of a bedding zone on the same area. Neanderthal behavioral patterns should be revised on the light of high resolution analyses, since diagenetic processes can obscure the existence of differentiated activity areas in the site.  相似文献

The comparative study of sedimentary fabrics in relation to archaeological fabrics in various levels of the sites of Cova Gran de Santa Linya (Middle and Early Upper Palaeolithic) and the Roca dels Bous (Middle Palaeolithic) has made it possible to analyse the formation dynamics of the deposits and determine the extent of disturbance of the archaeological levels by natural processes. To achieve this, diagrams and two- and three-dimensional indices were calculated from the azimuth and dip angle of natural clasts and artefacts. The results indicate that the sedimentary levels were formed mainly by planar fabric shape gravitational processes (low depositional angles), which differ notably from the archaeological fabrics they contain, characterised by a greater degree of isotropy. This difference in the fabrics would reflect human activity and indicates that the archaeological levels both in Cova Gran and Roca dels Bous have not been subject to significant natural modifications, and are preserved in situ.  相似文献

Excavations at Golson (22HU508), an archaeological site on the Yazoo River in western Mississippi, USA, produced an assemblage of over 4000 freshwater mussel shells, 77 percent of which were identifiable to species. Although limited spatial sampling of the deposits limits what can be said about past mussel community characteristics, twelve new river records for mussel species are derived from the assemblage. This typical result emphasises the value of archaeological shell assemblages for conservation biology and provides a rationale for why sites containing shell may be considered significant based upon their potential contributions to environmental history.  相似文献

This article reads Alice Munro’s “Material” as a staging of the failure of its narrator’s voice and understanding. Her failure exposes the limits of the mind to understand and language to represent, but it does so within a complex aesthetic structure that obliquely asserts the value of literature. This aesthetically realist story displays a deconstructive ethics that shows Munro working toward a literature free from phallogocentrism and pushing at the limits of logos itself. “Material” exposes the ethical risk and the power of writing, as well as the significance of that which lies beyond its ability to express.  相似文献

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
