Two locations adjacent to the great central oases of the Egyptian Western Desert experienced an unusual period of sedentism in the early to mid-Holocene. Around the Southeast Basin near Dakhleh Oasis and in the Wadi el-Midauwara above Kharga, areas sharing close cultural ties, groups of slab structure sites attest to increased sedentism spanning 2,500 years. Kharga seems to have been settled fairly continuously through the two and a half millennia, but little is known of subsistence practices in this location. Dakhleh experienced two episodes of increased sedentism. Early Holocene Masara groups occupied a well-watered location within a generally dry desert. In the wetter mid-Holocene, Bashendi settlers in large stone-built sites hunted, collected wild cereals, and may have kept herds. As the desert dried after 5300 BC, the settlers switched to a life of mobile forager-herders.

Charcoal forms a crucial source of archaeological and palaeoenvironmental data, providing a record of cultural activities, past climatic conditions and a means of chronological control via radiocarbon (14C) dating. Key to this is the perceived resistance of charcoal to post-depositional alteration, however recent research has highlighted the possibility for alteration and degradation of charcoal in the environment. An important aspect of such diagenesis is the potential for addition of exogenous “humic acids’ (HAs), to affect the accuracy of archaeological and palaeoenvironmental reconstructions based upon chemical analyses of HA-containing charcoal. However the release of significant quantities of HA from apparently pristine charcoals raises the question whether some HA could be derived via diagenetic alteration of charcoal itself. Here we address this question through comparison of freshly produced charcoal with samples from archaeological and geological sites exposed to environmental conditions for millennia using elemental (C/H/O) and isotopic (δ13C) measurements, Fourier Transform Infrared Spectroscopy (FTIR) and proton Liquid-State Nuclear Magnetic Resonance (1H NMR). The results of analyses show that the presence of highly carboxylated and aromatic alkali-extractable HA in charcoal from depositional environments can often be attributable to the effects of post-depositional processes, and that these substances can represent the products of post-depositional diagenetic alteration in charcoal.  相似文献

In the study area (the Upper Rhine Lowlands and the southern Black Forest), colluvial and alluvial sediments could be dated with the aid of 14C analysis, archaeological finds, pollen analysis and stratigraphic assessments. On the basis of these dated deposits, six different maps have been produced showing the distribution of the colluvial and alluvial sediments for the corresponding archaeological cultural periods. For each of these periods, the intensity of human impact on the environment has been estimated in relation to climatic conditions and different economic activities; for example, woodland clearance and mining activities.  相似文献

The presence of the flyThoracochaeta zosteraein cesspits had led to the unlikely interpretation that seaweed had been present in Mediaeval cesspitis. Archaeological and modern pupae fromT. zosteraewere sampled along with their probable larval diets (extracted plant material from cesspit and seaweed, respectively). The spacing between pupae and food for δ13C and δ15N was similar for both modern and archaeological samples. Modern pupae had isotopic ratios typical for marine invertebrates for δ13C. Archaeological puparia had isotopic values typical for terrestrial grazers (i.e., non-marine), indicating that there was no marine inclusion in the cesspits.  相似文献

The concept of modernity has played an essential role in the development of anthropological archaeology. Providing the philosophical foundation upon which both culture historical and processual archaeologies were constructed, the application of theories based in modernism has led to the persistence of essentialist notions concerning the archaeological records of both Western and non-Western peoples. Examining archaeological materials from the Muskogee Creek peoples of interior Southeastern North America, I contend that previous conceptualizations of modernity lack sufficient nuance to adequately address the diversity of cultural practices among the post-contact Creeks (circa A.D. 1550–1830). Rather than the dichotomous perspective of Western moderns and indigenous primitives that predominates, recent archaeological research in Southeastern North America reveals a cultural milieu in which dynamic, contested modernities were created by both the colonizers and the colonized.  相似文献

Before the arrival of the Spaniards in Peru in 1532, many different societies flourished in the coastal desert of southern Peru. Of these, one of the best known is the Nasca culture (living in the area between about 260 cal BC and 640 cal BC.), which created the famous geoglyphs on the desert floor. In this paper we present a numerical chronology for the cultural development in the valleys of Palpa, in the northern part of the Nazca region, which spans the time from the Archaic Period (starting there around 3760 cal BC) to the Late Intermediate Period (terminating with the arrival of the Spaniards in 1532 AD). The chronology is based on more than 150 14C samples collected by our project from well-documented archaeological excavations of 17 different sites in and around Palpa. Thanks to the advanced AMS-14C dating technique, demanding only few milligrams of organic material, we could focus on samples of plants, like beans, corn, or reed, representing single years of growth or use, and also on delicate materials like straw from clay bricks (adobe) and textiles. All single 14C dates were combined to cultural phases using a Bayesian statistical model, implementing the a priori information of the archaeological contexts, and adopting the relative ceramic chronologies available for this area.  相似文献

Abstract

Geoarchaeological research on the southern coast of Oregon brought to light archaeological evidence of early human occupation in the late Pleistocene. Indian Sands (35CU67) lies on a highly eroded deflated headland on the Oregon coast where previous surveys had found and dated surficial cultural materials as early as 8250 b.p. (uncalibrated radiocarbon years). Prior to excavation of Indian Sands, sediment and stratigraphic analysis, along with radiocarbon and thermoluminescence dates, established the existence of late Pleistocene deposits. The excavations confirmed the presence of buried cultural deposits containing lithic artifacts, charcoal, and fire-cracked rock. Dispersed charcoal from the floor of an artifactbearing level was dated to 10,430 b.p., more than 2000 l4C years older than any other Oregon coastal site.  相似文献

Abstract

The protection of Palestine's archaeological heritage faces several serious obstacles: unenforced laws, lack of public awareness, deterioration of Palestine's economic status, unregulated urban development, and the protracted political conflict between the Palestinians and Israelis. As a result, a significant number of archaeological features and sites have been vandalized, looted, or intentionally destroyed without compunction over the past several decades. The Palestinian-Israeli political conflict has negatively affected the archaeological heritage in “Area C,” which remains under complete Israeli civil and military control. This area includes nearly 60% of the archaeological heritage located within the Palestinian Occupied Territories, but the Palestinian Department of Antiquities and Cultural Heritage lacks the authority to monitor and protect these sites. Furthermore, the Israeli civil and military authorities in the West Bank do not provide the necessary protection of cultural heritage resources in Area C. The devastation of these resources throughout the Palestinian Territories provides the impetus for this research. The main aim is to identify the results of the political conflict on Palestinian archaeological and cultural heritage sites, using a case study at the site of Khirbet el-Lauz.  相似文献

Migration is a commonly used explanation for cultural change in world prehistory, and is also a central theme in the prehistory of the Pacific Islands. However it is rarely subject to direct archaeological research. This paper applies strontium and oxygen radiogenic/stable isotope (87Sr/86Sr, δ18O), and trace element concentration (Ba/Sr) analyses to 27 individuals buried at the archaeological site of Nebira (ca.720–300 BP), located inland on the South Coast of Papua New Guinea. The analyses seek to identify non-local individuals within the population and provide a more in-depth understanding about the social identity of the possible migrants in this community.The strontium isotope data indicates that five individuals were non-local to Nebira, having possibly come from a coastal location. Correlation with biological data, such as age and sex, also indicates that the pattern of migration at Nebira was not sex or age specific. The results support the archaeological findings that suggest the inhabitants from Nebira were in contact with coastal communities during a period in prehistory of increased cultural interaction. However, despite the considerable isotopic variation identified in the Nebira sample, it is also demonstrated that more research is needed to identify the possible origins of these non-local individuals.  相似文献

Abstract

There are roughly 2300 recognized archaeological sites in Taiwan. Under the Cultural Properties Preservation Law (CPPL) of 1982, archaeological heritage falls under the category of 'historic relics'. However, archaeological sites are not designated as such until they have been excavated and studied to prove their cultural value. Protection of the archaeological heritage has been reinforced through the Environmental Impact Assessment Act (EIAA), which regulates all environmental management plans. These study and determine the degree and scope of the potential impact of development on the cultural environment.

The CPPL was extensively amended and promulgated in 2005, and in this recent document discussed archaeological heritage in a distinct chapter (Chapter 3 with 16 acts). Furthermore, three regulations have been issued concerning the examination of designations of archaeological sites, qualification standards for excavation, as well as the administration and protection of archaeological sites. The newly enacted Cultural Law and Regulations confer competent authorities at all levels with all powers to supervise, administer, and then protect valuable buried cultural property. Although the protection of archaeological heritage has been better enforced since 2005, archaeological remains in Taiwan are still under various threats. Preservation of the cultural heritage is threatened by development, in many cases resulting in impasse. This paper discusses several recent examples of such dilemmas and presents a personal opinion on a better way to settle the controversy.  相似文献

ABSTRACT

Submerged shell midden sites and natural shell deposits can have similar characteristics and can be difficult to distinguish archaeologically. We excavated two test units from a large (at least 35 m×70 m) submerged shell mound in Fort Neck Cove in southern Rhode Island to assess whether it was natural or cultural in origin. This mound had been recognized as a potential archaeological feature as early as the 1970s. Excavation, radiocarbon dating, and subsequent laboratory analysis of excavated materials suggest that the mound was a natural oyster reef rather than a submerged archaeological site. No artifacts were found; there was no clear evidence for human modification of any shells; small species that would not have been targeted as food were present; and δ13C values of oyster shells from the mound were consistent with freshwater input into their growth environment, suggesting that they grew in an estuarine environment that did not exist prior to the inundation of the ponds. The stratigraphically oldest radiocarbon date we could obtain (430–190 cal BP, 2σ range), from 70 cm below the pond floor, placed deposition of shells at least 3,000 years after the inundation of the pond. The excavation methods that we used and the process of testing, irrespective of whether the feature is cultural, are valuable contributions to the methodological literature on submerged site archaeology and help provide insight for other researchers working to discern natural from cultural shell midden sites.  相似文献

The Projecto de Carta Arqueológica Subaquática do Concelho de Lagos (PCASCL) aimed to locate, identify and protect existing underwater cultural heritage within the district's coastal area. This project was based on a five‐phase methodology which included archival research, assessment, survey and conservation. PCASCL resulted in the discovery of five shipwrecks and several artefacts which were added to the Portuguese archaeological record. This also led to the development of a secondary project which focused on one of the five shipwrecks as well as proposals for an underwater archaeological park in Lagos.  相似文献

Understanding how to live successfully within our environment is among the most pressing challenges facing contemporary society. This paper probes the problem based on comparative analysis and discusses the relationship between the spatial–temporal distribution of the Neolithic cultural sites and the geographic context in the Hanjiang River Basin in the south of Shaanxi Province, China. Archaeological studies have identified 175 Neolithic cultural sites in the study area, with a sequence of Laoguantai (14C age 8–7 ka BP), Yangshao (14C age 7–5 ka BP) and the late period of the Neolithic Age (14C age 5–4 ka BP). The total number of archaeological sites, the distribution area and the density all showed an early ascending and later descending trend, but the proportion of the number of archaeological sites in the study area to the corresponding value of the entire Shaanxi Province declined sharply. Spatially, these sites were concentrated on the terraces of the Hanjiang River and its main tributaries with an altitude of 400–800 m. Multiple data were integrated to clarify the critical effects of tectonic and geomorphologic conditions on the distribution of the Neolithic sites. Further comparisons revealed the correlation of Holocene climate change and environmental evolution with the Neolithic cultural succession in the study area that ameliorated conditions to generally promote the development of the primitive culture while degeneration coincided with the culture's transition or interruption. The discussion on the origin of the primitive culture and the temporal–spatial distribution corresponding to the regional culture differentiation sheds light on the complex and dynamic human–nature interaction system during the Neolithic Age, thus emphasising the wider field-based investigation and high-resolution reconstruction works of the palaeoclimate and palaeoenvironment in the future.  相似文献

Radiocarbon (14C) dates are the most important means for determining the age of Holocene archaeological deposits. The theoretical physical basis of this method is by now unassailable, having been consistently tested and refined over two generations. However, the means by which this method has been applied and the interpretation of these results remain as key issues, particularly for complex archaeological discoveries that substantially affect our understanding of world prehistory and social evolution. Many factors can produce uncertainty or variation in the 14C concentrations of samples, even those that have been selected from the same archaeological context or event. A number of recent studies have also addressed the ways in which ambiguities and irregularities in the 14C calibration curve can affect the interpretation of archaeological dates and temporal patterns. Of greatest concern, however, is a growing practice of using only one or two samples to date a significant prehistoric context or event. The date of these events, usually relative to other human activities, often holds important theoretical implications for evolutionary anthropology and related disciplines. In this article, we demonstrate that such a practice is rarely adequate or acceptable. Rather, proper procedure requires a suite of dates that permit statistical verification that the deposit or event itself is being correctly dated. We present a detailed case study that highlights the importance of analyzing multiple samples of 14C from significant archaeological contexts.  相似文献

Radiocarbon (14C) dating of archaeological coastal sites in arid areas is challenging because of the relative rarity of datable terrestrial artefacts. Marine artefacts provide an abundant source of carbon, which is technically easy to date but radiocarbon dates need to be corrected for local variations from the global average marine 14C reservoir age (ΔR). In archaeological sites, this is usually done by the comparison of the 14C age measured between coeval pairs of terrestrial and marine samples that have no inbuilt age. Here, we present the results of a study that aims to determine the local 14C marine reservoir effect (MRE) along the Eastern coast of the Arabic Peninsula during the 4th millennium BC, a period of important cultural, demographic and social changes in this region. Previous estimates of the MRE based on associated shells and charcoal vary by about 400 14C yr and this is a serious limitation to the establishment of a precise chronology in the area based on marine material. In order to maximize the chances to obtain contemporaneous terrestrial–marine pairs for a new assessment of the MRE in this region we dated charcoal, shells, fish and turtle bones as well as human bones found in three recently and carefully excavated graves from Ra’s al-Hamra RH5. A large variability was found between charcoals (up to 240 14C yr) and marine specimens (up to 785 14C yr) present in the same grave. This variability was attributed to inbuilt ages, diagenesis and possibly environmental factors although taphonomic processes cannot be excluded. We discarded the oldest charcoals and used the 14C ages obtained on human apatite as a cut-off value to remove the marine outliers. Two out of the three graves provided terrestrial and marine assemblages which did not differ statistically and were used to calculate an average MRE of 645 ± 40 14C yr (ΔR = 255 ± 55 14C yr). This value is consistent with previous estimates based on the 14C dating of marine sediments off Pakistan and suggests stability of the MRE in the Arabian Sea since the 4th millennium BC.  相似文献

This essay is an analysis of archaeological contributions to the understanding of Nigeria's cultural history between ca. 2000 B.C. and A.D. 1900 focusing on the following themes: the origins of food production; development and transformations in metallurgical traditions; the beginnings of social complexity; and the character of state formation and urbanism. The transformations in everyday material life as a result of the entanglement with the Atlantic commerce and ethnoarchaeological approaches to understanding material culture and archaeological contexts also receive attention. The essay provides pathways to some of the turning points in Nigeria's cultural history, shows the convergence and divergence of cultural historical developments in different parts of the country, and identifies the critical gaps in archaeological research agenda.  相似文献

It is now three decades since Waterbolk introduced evaluation criteria to 14C chronology. Despite this, and other subsequent attempts to introduce quality control in the use of 14C data, no systematic procedure has been adopted by the archaeological community. As a result, our databases may be significantly weakened by questionable dates and/or questionable associations between dated samples and the archaeological phenomena they are intended to represent. As the use of chronometric data in general becomes more ambitious, we must pause and assess how reliable these data are. Here, we forward a set of evaluation criteria which take into account archaeological (e.g. associational, stratigraphic) and chronometric (e.g. pre-treatment and measurement) criteria. We intend to use such criteria to evaluate a large 14C dataset we have assembled to investigate Late Glacial settlement in Europe, the Near East and North Africa, supported by the Leverhulme Trust. We suggest that the procedure presented here may at least form the basis of the development of more rigorous, scientific use of 14C dates.  相似文献

Multi-isotope fingerprints in the bioapatite of archaeological skeletons are mostly superior over single isotope analyses for provenance studies. Gaussian mixture model (GMM) clustering is a novel tool for a similarity search among multidimensional data sets and at the same time permits the evaluation of the structural importance of particular isotopic ratios in the data set. We applied three GMM clustering experiments on multi-isotope fingerprints—stable strontium (Sr), lead (Pb) and oxygen (O) isotopic ratios—established in 217 archaeological animal bones excavated along a specific transect across the European Alps. This reference region had been in use since prehistoric times by humans who crossed the Alps from north to south, and vice versa. The resulting clusters permit a spatial assignment of the specimens with a very high probability, in particular with regard to the geological complexity of the region. A combination of Sr with Pb stable isotopes led to an optimal differentiation between the southern and northern Alpine forelands that cannot be distinguished from each other by 87Sr/86Sr ratios alone, while the contribution of δ18O is not particularly high. The isotopic mapping and subsequent cluster analysis is suitable for the analysis of archaeological human finds and the reconstruction of the direction of transalpine mobility and trade.  相似文献
