Abstract

Aerial photography has been employed by archaeologists since 1906. This study discusses the application of image processing of historical photographs as an aid to archaeological excavations at two California mission sites.

Research on the Mission Vieja de la Purisima site involved the mapping of the Old Mission complex, destroyed by an earthquake and mudslide in 1812. Optical means of multiple-image registration and scale change were employed. The second study involved the digital transformation of an historical photograph of Mission San Buenaventura from its oblique perspective into a “psuedo-vertical” format.

Information obtained in these studies is being used by archaeological researchers and has been found accurate and extremely useful. The preliminary mapping of the Mission Vieja de la Purisima has aided in the preservation of the area and played a major role in the mission's being designated as a California and National Historical site.  相似文献

Abstract

The fluting of Early Paleo-Indian bifaces and associated failure rates have received considerable archaeological attention—perhaps at a scale exceeding its comparative importance. Nonetheless, if we are to properly evaluate explanations of the origins and purpose of fluting and the function of particular sites in Paleo-Indian settlement systems, estimates of failure rates are required. To date, such estimates have been based largely on experimental replication and rarely on a1Achaeological data, and it is suggested the experimental estimates are inaccurate. In order to overcome these problems, three interrelated, yet independent, methods of estimating fluting failure rates from archaeological data are developed and applied to data from the Parkhill site in Ontario and the Windy City site in Maine. The consistency in the results obtained by these methods inspires faith in their relative accuracy. The results suggest failure rates, at least at these sites, were not on the scale often assumed by previous investigators, being on the order of only 10–15% or less.  相似文献

Abstract

The project developed at the Lemba Experimental Village in Cyprus seeks to explain some aspects of the workings of archaeology through the medium of an ongoing and dynamic research project. The Lemba Experimental Village was established in 1988 with a view to understanding site formation processes through the construction of full-scale experimental buildings of the Chalcolithic period (3500–2800 BC). Experiments have been carried out with mud construction, lime plaster making and building construction. Monitoring and recording of construction and erosion processes provides a long-term history of events on the site which can be related to the deposits and features encountered when excavation is undertaken. Comparative information has been obtained from the structural analysis and excavation of buildings abandoned 25–30 years ago in the village of Souskiou, where similar deposits are encountered. The results of the work at Lemba and Souskiou are used as a comparative database for understanding deposits on prehistoric archaeological sites. The juxtaposition of the experimental building constructions with completed excavations at Lemba has led to the emergence of a policy of site presentation in which the methods of a particular form of archaeological research – experimental archaeology – constitute the main focus of interest on the site. This has been encouraged in the development of the site as a visitor centre, with an annually changing programme of new buildings being constructed and older ones being destroyed.  相似文献

Abstract

Few sites relating to Archaic procurement of copper have been archaeologically investigated in the southern part of the Lake Superior basin. The Duck Lake site, located in the Ontonagon River watershed of Michigan's Upper Peninsula, is within the source area for native copper. Investigations at this site reveal a field camp consisting of one or more occupations by Late Archaic groups. Lithic analysis demonstrates a strong reliance on non-local raw materials, and suggests a degree of residential mobility within a region known to the occupants. Lithic material was obtained through embedded procurement and exchange with more distant groups. Copper likely entered the early Late Archaic exchange system in the Midwest through frequent interactions and trade between groups, and appears consistent with a down-the-line model of exchange.  相似文献

Temporary consolidation is widely used to protect delicate artefacts or other fragile relics in art conservation. Although cyclododecane is extensively accepted, the safety‐related issues have become an increasing concern and its short working time is always annoying. Inspired by its low melting point, polar structure, well‐established safety profile, easy local availability and low cost, we propose menthol as a new temporary consolidant on the new excavation site of Qin Shihuang's Terracotta Army. In this paper, we offer a preliminarily exploration of the kinetics of menthol sublimation on two different matrices, its residue after volatilization, its penetrability and distribution in simulated terracotta samples, as well as other important properties in the laboratory. The results obtained from these tests reveal that the sublimation of menthol can be a zero‐ or a first‐order process, depending on the porosity of the matrices, and its best operational temperature resides in the range of 60–80°C. Finally, two field cases at the archaeological site of Qin Shihuang's Terracotta Army are presented to show that menthol is a very effective temporary consolidant.  相似文献

Abstract

The Toqua site (40MR6) is one of the most thoroughly excavated Late Mississippian mound sites in East Tennessee. The site has been a focal point of research on late prehistory in southern Appalachia, but there are issues surrounding its chronological placement. The radiometric dates obtained for the site in the 1970s and the archaeomagnetic dates reported in 1999 have large standard deviations. These dates are too imprecise to be useful for a temporal placement of the site that is clear enough for current discussions of the development of Mississippian culture. A newly obtained Accelerator Mass Spectrometry (AMS) date from the large platform mound (Mound A) allows a reevaluation of the occupation sequence of the Toqua site. This date provides an anchor for a refined chronology for Mound A. In addition to the new AMS date, this refined chronology is based on complementary lines of evidence, including architectural evidence, mortuary practices, pottery traditions, and shell gorget styles.  相似文献

In Trade, Tribute, and Transportation, Ross Hassig argues that indigenous towns in the northern Basin of Mexico during the colonial period were largely self-sufficient. They traded with Mexico City mostly in elite goods, but for the most part they produced for their own subsistence or traded with nearby towns. Chemical characterization by instrumental neutron activation analysis (INAA) and portable X-ray fluorescence (pXRF) of ceramics and obsidian from post-conquest contexts in Xaltocan, a site in the northern Basin of Mexico, reveals that Hassig’s model is partly correct for describing Xaltocan. The town focused on trade with nearby towns and it produced some ceramics for local consumption. However, Xaltocan was hardly isolated and self-sufficient in the post-conquest period. Instead, the data suggest that the people of Xaltocan also obtained ceramics and obsidian from a greater variety of sources than under Aztec domination. Rather than being an isolated rural site, Xaltocan either increased its external connections and number of trading partners after the Spanish conquest, or it managed to obtain a greater variety of products than before through a bustling market system.  相似文献

A large number of Mediterranean Group vessels were recovered at the Etruscan site of Spina in northern Italy and dated from the 6th to the 3rd century BC. In this work a number of vessels belonging to the so-called “Group II” were analysed. The samples are mainly Alabastra, Oinochoai, Amphoriskoi, and Hydriai, in general opaque and deeply coloured. The aims of this study are: 1) to characterize these samples since there is a lack of data in literature regarding Mediterranean Group II; and 2) to compare the data obtained with that of glass for previous centuries (Mediterranean Group I) recovered at the same site in order to establish whether they could have the same origin. The chemical analyses of major and minor elements were carried out by electron microprobe and the nature of the opacifying and colouring agents was determined by X-ray diffraction. The sample set is relatively homogeneous and most of the samples can be classified as Low Magnesium Glass produced with natron and a calcareous silicatic sand. The XRD analyses proved the use of lead antimonates in the manufacture of yellow decorations and of calcium antimonates in the white and light blue decorations. The consistency of the chemical compositions of Mediterranean Groups I and II samples makes it possible to hypothesize a common origin.  相似文献

The objectives of this work are to present a set of methodological procedures to analyse commingled bone assemblages (e.g. secondary burials), in order to build the mortality profile of the Paso Alsina 1 site and discuss the obtained age at death distribution in a context of hunter‐gatherer populations that inhabited the eastern Pampa–Patagonia transition (Argentina) during the Final Late Holocene. The Paso Alsina 1 site is a formal disposal area of inhumations composed by multiple secondary burials dated at ca. 500 14C years BP. The site is comprised of a minimum number of 77 individuals, represented by both sexes and all age categories. The mortality profile is characterized by a bimodal pattern with a peak of greater representation of individuals younger than 3 years and another comprising the range between 20 and 34.9 years old. These results are discussed in relation to the paleopathological information available for the site, indicating that individuals suffered mainly disruptions in growth and development by systemic stress. The mortality profile obtained suggests that this skeletal series would not have formed as a result of a catastrophic event. On the contrary, it is an atricional mortality profile, consisting of individuals who died at different times and places and for varied reasons. Later, skeletal remains were grouped into secondary bundles and simultaneously buried at the site. Body manipulation and secondary burials are common in the context of a social reorganization that occurred in the area and in neighbouring regions during the Final Late Holocene.

Graphic and metric information about the site and its environment and about the different structures and artefacts located are indispensable for the optimal management of an archaeological excavation. A Geographic Information System (GIS) proves useful in managing and analysing information and data obtained from different sources. Two techniques of data capture, Terrestrial Laser Scanning (TLS) and close range photogrammetry, are used to generate accurate and high-resolution 3D models of a cave, the silos and a combustion structure at the Can Sadurní site (Begues, NE Spain). This site is especially noteworthy on account of its complete stratigraphy of the Catalonian Holocene. The capture and processing of the photogrammetric and TLS data used to generate 3D models are discussed in detail. These models cannot be obtained by classic archaeological techniques since the record is made layer by layer, approximately one decimetre apart, with the result that the information between the layers is lost. Our findings highlight the potential of these techniques for obtaining accurate and photorealistic models that facilitate a complete analysis of the available information at an archaeological site.  相似文献

The paper applies Bayesian statistical modelling to radiocarbon dates obtained for a stratigraphic sequence comprising occupation features and superimposed burials from the Late Mesolithic (c.7400–6200 cal BC) to the Mesolithic–Neolithic transition (c.6200–5900 cal BC), from Vlasac in the Danube Gorges region of the north‐central Balkans. This sequence, investigated in the course of excavations at the site in 2006–9, yielded stratigraphic evidence of the transformation of local forager populations as a result of contact with Neolithic communities. Our paper provides a reliable chronological framework for changes from Late Mesolithic burial rites to new, Neolithic types of ornamental beads at the top of the sequence. The use of the same burial location and continuities in burial rites over a considerable period of time raise significant questions about the role of tradition and the potential for enduring practices in prehistoric societies.  相似文献

Data of high resolution for reconstructions of archaeological site formation processes can be obtained only by the use of precise excavation methods and comprehensive recovery techniques using fine-mesh water screening, followed by meticulous sorting and quantitative studies of all the small organic components from the screens. These methods are generally used at human occupation sites, but are not often employed at paleontological or mixed human-carnivore sites. At the site of Bois Roche, an Upper Pleistocene hyena den, we have used these meticulous recovery techniques in combination with absolute dating, geoarchaeological observations, taphonomic analyses, studies of microvertebrates and pollen analysis. Correlation of the site environmental data from pollen and microvertebrate assemblages with the vegetation record of a deep-sea core taken in the Bay of Biscay have allowed us to constrain the ages provided by ESR dating of bovid teeth and to reconstruct the physical environment of the site with a degree of confidence rarely achieved by the use of fossil remains from archaeological sites alone.  相似文献

The remains of six species of geese are commonly recovered from archaeological sites in Britain dating from the Saxon and later periods. However, identification of this material to species level is hampered by a lack of morphological variation and a large overlap in size. To address this issue we obtained DNA sequence data for a section of the mitochondrial cytochrome b gene from modern samples of each species, and successfully identified several DNA markers for Branta species. No markers were found within the cytochrome b gene for the genus Anser. Ancient DNA techniques were then used to recover DNA from goose bones excavated from two archaeological sites. The DNA sequences enabled identification of Barnacle goose (Branta leucopsis) from one site and confirmed the presence of Anser species at another. © 1998 John Wiley & Sons, Ltd.  相似文献

The early Epipalaeolithic site of Ohalo II offers evidence that, some 19 400 years BP, prehistoric people on the shore of the Sea of Galilee exploited birds in large numbers as a food source and for the decorative value of their feathers and claws. The superb preservation of even the most delicate fauna at this site enabled an extensive analysis of a type rarely possible with avian remains of this antiquity. Certain types of birds were obtained preferentially, although a broad variety of avifauna was taken; preliminary analysis of some 488 identifiable bone fragments indicates that 16 families, 40 genera, and 68 different species are represented in the archaeological assemblage. As might be expected from a lakeshore site, the remains of waterfowl abound. The most diversity within a family occurs among the Anatidae, with ten genera and 22 species; however, the most frequently occurring birds are those of the family Podicipidae, or grebes, which account for approximately one-third of the assemblage. Species common to a variety of other environments are found in significant numbers as well (namely the Accipitridae). Large birds dominate the assemblage and the number of species represented by each family is disproportionate to the numerical frequency of those species at present, with passeriformes relatively poorly represented. The regular migration pattern of birds today broadly indicates that the site was occupied during the months of September–November and February–April. There are, however, a number of species that appear in this region today only from December through to March, which might indicate a longer, semi-permanent encampment. A biseasonal, or perhaps extended winter occupation pattern at Ohalo II seems to support a shift away from the generalized foraging economy of hunter–gatherers and to indicate the onset of planned intensive collecting, thus foreshadowing the initial steps toward sedentism. © 1998 John Wiley & Sons, Ltd.  相似文献

One of the largest and best known sites of the Central European Gravettian is the Kraków Spadzista site. This article summarizes archaeological, palaeontological, and zooarchaeological data from the site, obtained in the course of more than 40 years of excavations and studies. The site is known mainly from the discovery of the large mammoth bone accumulation in trench B. During field work conducted in a few trenches located close to this assemblage, numerous human artifacts and faunal remains were found. On the basis of analyses of lithic materials, faunal remains, and radiometric data it is concluded that the Krakow Spadzista site was frequently re-occupied during a few weeks or months, by groups of Gravettian hunters in the period 24–22,000 rcyBP This short-term camp site was related to mammoth hunting. The analysis allowed identification of three possible activity zones, characterized by the presence of different groups of flint tools, fireplaces, and different faunal assemblages: a camp area, a lithic workshop, and an animal-processing area, besides the well known accumulation of mammoth bones.  相似文献

The aim of this paper is to fill the gap in data relating to local supply chains in the proximity of nuclear sites by investigating the site of Sellafield in West Cumbria, UK. Using information obtained from invoice data provided by Sellafield Ltd, the site-licenced company, and from primary research, the authors explore the relevance of nuclear procurement within the area, by evaluating levels of economic leakage and seepage resulting from suppliers’ subcontracting and work carried out locally. The study shows that the presence of a nuclear site has a crucial role for the surrounding area and for its economy. The results indicate a significant level of financial retention in the area with regard to work carried out in-house and local subcontracting at a first tier. In particular, the results identify cash flows related to second-tier suppliers located in West Cumbria, demonstrating that about a third of the total work carried out or subcontracted at the nuclear site stays in the area. These findings underline the significant impact of Sellafield on the West Cumbria economy and, more generally, provide an overview of the importance of nuclear sites for local supply chains in peripheral and remote areas.  相似文献

Abstract

The Abbeydale Industrial Hamlet (Grid Reference SK 326820), known historically as the Abbeydale Works, was built over a long period of time for the manufacture of edge tools. The earliest reference, 1676, described the site as a cutlery grinding shop. By 1714 it was established as an agricultural edge tool manufactory. The extant buildings date between 1785 and 1842. By the beginning of the nineteenth century the site was one of the largest on Sheffield's rivers, and a highly successful business in scythes, sickles, hay knives and other agricultural tools was developed until the Works closed down in 1933. This article traces the history of the site and also covers the period of restoration in the late 1960s, culminating in its opening to the public as a site museum in 1970. Some of the problems encountered during the restoration are discussed.  相似文献

Abstract

Located in a spring-fed meadow at 2620 masl, Helen Lookingbill is a stratified, high-altitude open site in the Washakie Range of the Absaroka Mountains in NW Wyoming. The site contains cultural material ranging in age from Paleoindian through Late Prehistoric periods. Although the densest cultural deposits date to the Early Archaic (8000–5000 b.p., uncalibrated), other time periods are well represented. A 10,400 year old layer comprises the earliest component (Haskett/Hell Gap) in the main excavation area; above it is a series of Late Paleoindian, Early Archaic, later Archaic, and Late Prehistoric components. The major materials at the site are chipped stone and bone, while a deer bone bed dating between 6500 and 6800 b.p. is contained within the main excavation block. In addition to deet; the site contains the remains of mountain sheep, bison, porcupine, and other mammals. Located on and near both quartzite and chert stone sources, the mountain meadow served as a prehistoric camp site and yielded evidence of tool production, heat treatment, refurbishing, and use. Interdisciplinary research provides much information pertinent to understanding the nature of site occupation with implications for regional cultural dynamics, high altitude hunter-gatherer adaptations, and site formation processes.  相似文献

Abstract

Tell Qasile, in the area of the Eretz Israel Museum in north Tel Aviv, is the location of a small town founded in the twelfth century BCE. The site has significant importance for the study of various aspects of the Iron Age period in Israel. The buildings at the site were constructed of mudbricks on stone foundations. Conservation of buildings at the site was carried out using three methods: 1) building roofs (in roofed areas no other conservation was needed); 2) conserving mudbrick walls by plastering them in modern plaster made up in imitation of ancient building material; 3) full restoration of buildings up to roof level (carried out in one case). These methods were successful, and, due to the location of the site within a large museum compound, it is utilized for archaeological education, mainly of schoolchildren.  相似文献
