Recent innovations in portable energy-dispersive X-ray fluorescence (PXRF) spectrometry have increased its utility for the geochemical characterization of obsidian artifacts for archaeological provenance research. However, concerns over the utility of PXRF instrumental analyses have been raised, focused on the validity and reliability of the geochemical data produced. Here we adopt the framework of Richard Hughes (On Reliability, Validity, and Scale in Obsidian Sourcing Research, 1998), whereby reliability addresses instrument stability and issues of measurement while validity pertains to an instrument’s ability to discern geochemical source provenance. This is done in order to test the utility of PXRF instruments for archaeological provenance research. k-Means cluster analysis was used to test the accuracy of PXRF through statistical comparison of data acquired via laboratory and portable energy-dispersive XRF instruments. Multivariate analysis was employed to demonstrate obsidian source representation at two Classic Maya archaeological sites in southern Belize – Uxbenká and Ek Xux – and to test the validity of data obtained from a PXRF instrument in answering archaeological research questions pertaining to regional interactions between lowland Maya polities. Results suggest that portable XRF instruments produce internally consistent results. However, data acquired from a PXRF instrument are not statistically equivalent to other XRF instruments. This is to say that while PXRF is not a reliable technique, it is valid for questions pertaining to geochemical source representation. 相似文献

Elective Affinities: Musical Essays on the History of Aesthetic Theory collects a selection of Lydia Goehr's recent essays. In them she traces "a history of attraction and reaction … of music to philosophy, drama, birdsong, crime, film, and nationhood" (ix). Goehr examines the ways that philosophers, the ideas that they present, and works of art display "elective affinities". Her procedure is like that of an art historian who presents parallel slides to reveal visual affinities, even between artists who themselves were unaware of each other. Her analyses are erudite, lucid, and always suggestive, but what I found most admirable in Elective Affinities is Goehr's extraordinarily brave experimentation with a novel form of philosophy-writing, the adumbration of which is the focus of this review. Her book is strange enough to be genuinely magnificent and lastingly influential. 相似文献

ABSTRACTNorman H. Hardy is not a well-known historical character, so an element of salvage exists in bringing his art and book illustration to a wider audience. His short career as an artist with the Sydney Mail and the 68 paintings in The Savage South Seas in 1907 open up a wider discourse concerning the links between art and photography, between visitation and recording in the field, between art and journalism, and between popular imagination and the publishing practices for illustrated travelogues. Hardy's paintings of Papua, Solomon Islands and New Hebrides reached a wide audience and provide a close-up, intimate record of Indigenous life in the islands, as well as hinting at complex encounters between Islanders and traders. The visual evidence in The Savage South Seas also contributes to debates about the motivations of early 20th-century Euro-American travellers, authors and purchasers of books on the Pacific and provides yet another citation of notions of faraway lands and people in the Pacific as perceived by distant readers and audiences. 相似文献

Integrating portable X-ray fluorescence (pXRF) instrumentation into archaeological investigations has generated as much interest as skepticism because several characteristics of the technique limit analytical accuracy and precision. This paper seeks to explore inter-instrument performance in order to assess the potential pXRF instrumentation has in examining the elemental composition of lithic raw materials. Two pXRF instruments, Delta and Omega models both manufactured by Olympus Innov-X Systems, were utilized to obtain the trace element signatures of five fine-grained volcanic sources and four obsidian sources in the Great Basin. We compared the two portable instruments to a wavelength-dispersive instrument extensively calibrated with geologic standards and to a commercial benchtop energy-dispersive system. Our results suggest that the relationships between the data produced by these different instruments are complex, and as we look to the future of pXRF use in archaeological analysis we argue that that the same strict protocols applied in laboratory-based XRF analyses, involving instrument calibration, evaluation of inter-instrument performance, and comparison to accepted geologic standards, need to be applied in pXRF analysis. 相似文献

Uranium-series age estimates for rock art in southwest China 总被引:1,自引:0,他引:1
We report the first uranium-series age estimates for rock art in China. Calcite bracketing a paint layer was used to constrain the age of a naturalistic outline hunter-gatherer painting in the Jinsha River area of northwest Yunnan Province (southwest China). The rock paintings in this region are unique in style and content compared with other bodies of rock art in China, which are dominated by Neolithic subject matter. The minimum and maximum ages were determined using isochron techniques on multiple samples of calcite from above and beneath the paint layer. A large painted deer head was dated to between 5738 and 2050 years. This painting and underlying flowstone are superimposed on older paintings that suggest the older paintings are at least 3400 years old, if not older than 5738 years. The results indicate for the first time that Jinsha River rock art is older than other forms of rock art in the region and show that rock art likely extends back to at least the transition from the Palaeolithic to Neolithic in this part of China. 相似文献

This article explores the relevance of acoustics as a factor for in the production and active use of Levantine rock art in Spain. The renowned rock art area of La Valltorta Gorge serves as a case study. Two experiments are described; the first assessed whether the sites with the most painted motifs had better acoustics than those with fewer motifs. The second tested which areas in La Valltorta Gorge had better acoustics and whether there was a difference between the acoustics of the decorated area and the contiguous sectors of the Gorge where no paintings have been found. In both experiments different sounds and pitches were used. The results suggest a strong relationship between the painted areas and the sonority of the place, with the major sites generally having provided the best results, with the exception of the sonority when facing the rock art panels. It is suggested that La Valltorta Gorge was chosen to be decorated with a view to increasing the perceptual impact of the rituals that may have been held at rock art sites due to the amplification caused by the echoing and resonance. 相似文献
