Within the aim of contributing to the artisanal craft history at Sagalassos (SW-Turkey), an archaeometric programme including thin section analysis, ICP-MS and multivariate statistics was developed to define the variability on a provenance and/or technological scale of the Classical/Hellenistic ceramic assemblage of Sagalassos and Düzen Tepe. The obtained data were used to evaluate the extent and variation of local pottery production. Petrographic and geochemical analysis as a grouping technique proves to be conditional for documenting the variation in ceramic wares present on both archaeological sites. Elemental evidence supports local production activities between Classical and Hellenistic times, documenting a deliberate change in treatment of raw materials during the Late Hellenistic period in function of ware groups. 相似文献

This paper details the chemical sourcing of 135 obsidian artefacts from Çatalhöyük, a Neolithic site in central Anatolia, the trace-elemental analyses being undertaken in two laboratories using ICP-MS, ICP-AES and LA-ICP-MS. The material is assigned to three sources in Cappadocia: Göllü Da?-east, Nenezi Da? and Ac?göl West. The various interrelationships of technology, raw material and date are considered, the data suggesting an increased reliance upon the Nenezi Da? source in the latter part of the Early Neolithic, a shift that coincides with, and is related to, the introduction of new blade technologies. 相似文献

We report geochemical analysis of seven rock specimens and six stone artifacts from Nihoa and Necker Islands, Hawai'i. The analyzed rock specimens exhibit chemistry consistent with published data sets and establish a major element distinction between Nihoa and Necker. Their trace element data indicate that the analyzed rocks and artifacts are local in origin and they reliably discriminate from sources on Kaua'i. These preliminary results support Emory's thesis that early (archaic) Hawaiian colonists on Nihoa and Necker relied on their local basaltic stone to manufacture stone tools, containers, and other portable objects. 相似文献

Artifacts made from sinistral (left-handed) whelk shells are commonly found at inland archaeological sites in eastern North America. Past attempts to source the coast of origin of these marine shells based on chemical analyses have provided tentative results. A knowledge of sinistral whelk natural history is essential before attempting shell sourcing studies. The common occurrence of sinistral whelks in the Gulf of Mexico and their uncommon occurrence along both the South Atlantic and Mid-Atlantic bights are documented. Critical biogeographical and morphological information is presented, as well as a new method of sourcing artifacts based on spire-angle measurements. Sinistral whelk artifacts from Spiro, East St. Louis, and Cahokia probably came from the eastern Gulf of Mexico. 相似文献

Obsidian was broadly used along the Andean Cordillera in South America. Particularly in Peru, its use can be traced to the earliest human occupations, continuously through pre-Columbian times to contemporary Andean agro-pastoralist societies. In order to distinguish the provenance of obsidians from Peru, this paper reports a new X-ray fluorescence (XRF) analysis on several obsidians obtained in surface collections of the Ayacucho region. The analysis and source determination were made by XRF on 52 specimens. The source assignments involved comparisons between the compositional data for the specimens and the University of Missouri Research Reactor (MURR) XRF obsidian database for sources in Peru. After analysing the samples, obsidian sources were recognized and documented. All had small nodules not larger than about 4 cm. They were recovered from Ñahuinpuquio and Marcahuilca hill which belonged to the previously identified Puzolana source. Another identified source was the well-known Quispisisa, located 120 km south of the city of Ayacucho, and distributed through a vast region in central Peru. The results expand previous observations made on the obsidian provenance at Ayacucho Basin, as well as the extension of the Puzolana source between Yanama and Huarpa hills, south of Ayacucho city. 相似文献

To assess the analytical accuracies and precisions of archaeometric elemental analyses by different techniques, a relatively homogeneous material such as obsidian must be studied. An assessment of published elemental concentration data from two Anatolian obsidian sources shows that while in most cases analytical accuracy is as high as is commonly expected, in some cases it is not. It also shows that the dispersions of elemental concentration data (indicators of analytical precisions) coming from modern analytical procedures are akin to the estimated homogeneity of the obsidian. Based on this latter observation, if one has element dispersion data from a single analytical technique, with a single source of obsidian as a control, data sets that contain multiple, but similar sources of obsidian may be differentiated. 相似文献

We report on energy-dispersive X-ray fluorescence (EDXRF) sourcing of 807 basalt artifacts and 34 basalt ecofacts recovered from stratified midden at Nu‘alolo Kai, Kaua‘i. These data are compared with EDXRF analyses of 473 alluvial pebbles from Waimea Canyon, 34 adzes from the Kaua‘i Museum, and published geochemical data for Kaua‘i basalts. Formal tools, such as adzes, chisels, and mirrors were predominantly manufactured from sources not available at Nu‘alolo Kai. Most adzes and chisels are consistent with sources available elsewhere on Kaua‘i, but two basalt mirrors are outside the expected geochemical range of Kaua‘i basalts. In contrast, almost all expedient tools were manufactured from basalts available at Nu‘alolo Kai. These findings support the existence of an island-wide distribution system for adze material on Kaua‘i, and challenges extant models of pre-contact Hawaiian economics to consider the mechanisms through which specialized commodities were produced and distributed. 相似文献

Petrographic analysis and INAA geochemistry of prehistoric ceramics from Robinson Pueblo, New Mexico

The examination of thin sections is a successful method for discovering provenance groupings of archaeological ceramics if non-clay inclusions in pottery paste can be identified with petrographically distinctive geologic sources. When this is not the case, geochemical analysis must be employed to search for more subtle evidence of such groupings. This situation is likely to arise in studies, such as the present one, where the objective is to discern local or subregional patterns of pottery manufacture and exchange. Ninety potsherds from site LA46326 in New Mexico were subjected to both INAA and petrographic analysis. The results of this conjoint approach are assessed in relation to geochemical theory and are analysed graphically and statistically. 相似文献

Galena has been recovered mostly in mortuary contexts – burial mounds, burial caves, and associated mortuary facilities – from Middle Woodland sites in the Southeast. Three small pieces of galena from the Cork site (22OK746) in northeast Mississippi came from midden deposits at a site with no mound or burials. Lead isotope analysis was used to source the samples to the Central Missouri-Tri-State-North Arkansas region. Isotopes provide an excellent sourcing method because their ratios are stable and large comparative source datasets are available. Recovery bias may have led to underestimation of galena presence in Middle Woodland habitation sites. 相似文献
