Lapa clas Boleiras rockshelter, a Paleoamerican archaeological site in Central Brazil, was intensely occupied by humans from 10,000 C-14 BP (11.8 cal kyr BP), until approximately 7500 C-14 BP (8.4 cal kyr BP). In this paper we present some interpretations about the formation processes operating on the site. One of our main conclusions is that the bulk of accumulated sediments at the site is of anthropogenic origin: they are constituted by volumetrically significant quantities of plant ash remains, what is somewhat unexpectedly in view of prevailing models about the lifestyle of Paleoamerican hunter-gatherers in South America. The evidence we discuss below is also consistent with paleoenvironmental data that suggest a dry period during the mid-Holocene in the region, probably leading to a decrease in human occupation [Araujo, A.G.M., Neves, W., Pilo, L.B., Atui, J.P., 2005. Holocene dryness and human Occupation in Brazil during the `Archaic Gap`. Quaternary Research 64, 298-307]. We surmise that both factors underpin a surprising reduction in sediment accumulation at the site during the mid-Holocene.

In this article we present some results of ground-penetrating radar (GPR) studies carried out at the Lapa do Santo archaeological site. This cave is within the Lagoa Santa karstic region, Minas Gerais State, Brazil. Results from 44 GPR profiles obtained with 400 MHz shielded antennas indicated anomalous hyperbolic reflections and areas with high sub-horizontal reflection amplitude suggesting archaeological and geological potential targets, respectively. These results were encouraging and were used to guide excavations at this site. Excavation of test units (metre by metre) allowed identifying an anthropogenic feature, e.g., a fire hearth structure and natural features, such as a stalagmite and top of bedrock. Results also indicated the importance of the GPR survey as a tool for orienting archaeological researches, increasing the probability of finding archaeological interest targets in an excavation program in an area of environmental protection.; Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP), a Brazilian state level research agency; Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP), a Brazilian state level research agency [04/01321-6, 06/50720-6, 01/06881-1]

O objeto de estudo desta pesquisa é o sítio arqueológico Capelinha 1, situado nas proximidades da cidade de Cajati-SP. Tanto sua implantação na paisagem quanto suas características estruturais - particularmente sua composição conchífera - sugerem, em princípio, sua inclusão na categoria dos "sambaquis fluviais", encontrados no médio vale do Ribeira. A presença, porém, de uma indústria lítica associada à Tradição Umbu, inserida em uma estratigrafia em que predomina a matriz conchífera, contribui para a indefinição da natureza cultural do sítio e uma conseqüente dificuldade em relacioná-lo ao contexto arqueológico regional. Assim, o objetivo precípuo desta pesquisa é investigar os processos de formação do sítio Capelinha, procurando solucionar as questões por ele apresentadas e inseri-lo no contexto arqueológico do médio vale do Ribeira, com reflexos na arqueologia do Brasil meridional. Esta pesquisa é integrada ao projeto temático Investigações Arqueológicas e Geofísicas nos Sambaquis Fluviais do Vale do Ribeira de Iguape, Estado de São Paulo, apoiado pela FAPESP; The study object of this research is the Capelinha 1 archaeological site, located in the outskirts of Cajati-SP. Both its placement in the landscape and its structural characteristics - particularly its conchiferous composition - suggest...

O objetivo do presente trabalho é o estudo da tecnologia de produção artefatual lítica lascada e suas cadeias operatórias em sítios líticos a céu aberto localizados no nordeste do Estado de São Paulo. Inicialmente foi levantada a bibliografia amadora e especializada dentro da área de estudo, dedicando atenção às tecnologias líticas produtivas e procurando nelas tópicos como preferências locacionais dos sítios líticos e os tipos de matérias-primas e seus suportes; em outras palavras, as economias de matéria-prima levadas a cabo pelos artesãos. Todo o aporte teórico-metodológico do conceito de cadeia operatória foi empregado, inclusive buscando-se o gestual dos artesãos - análise diacrítica, tentando reconstruir por meio do processo operatório e seu gestual o projeto mental do artesão, que se encontra sob uma matriz técnica, a tradição cultural. Por fim apresentamos os resultados das análises alcançados, sintetizando as cadeias operatórias praticadas e ilustrando os artefatos líticos por meio de croquis. Embora tenham sido estudados diretamente os artefatos líticos, com atenção a seus atributos técnicos, é fato que representam mais do que um contexto particular, e propiciam, mesmo que indiretamente...

A arqueometria é uma área consolidada, com ampla utilização de métodos analíticos nucleares destrutivos e não destrutivos para caracterização, proteção e restauração de peças arqueológicas. O presente projeto teve como objetivo estudar a composição química elementar de amostras de fragmentos cerâmicos encontradas no sítio arqueológico São Paulo II localizado na calha do rio Solimões, próximo ao município de Coari na Amazônia Brasileira. Realizou-se a caracterização das amostras pela determinação de Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Sb, Sm, Rb, Sc, Ta, Tb, Th, U, Yb and Zn por meio da análise por ativação com nêutrons (NAA). A partir da composição química da cerâmica, foi possível definir o agrupamento de amostras em função da similaridade/dissimilaridade da composição química presente no material cerâmico. O agrupamento foi interpretado por métodos estatísticos multivariados como análise de cluster, análise de componentes principais e análise de discriminante. Foram selecionadas, a partir da formação dos grupos, 7 cerâmicas com o objetivo de elaborar o horizonte temporal do sítio, realizado por termoluminescência (TL) e ressonância paramagnética eletrônica (EPR). A temperatura de queima da cerâmica foi determinada em 6 fragmentos por meio da técnica de EPR. Os resultados apresentados neste trabalho podem contribuir com os estudos arqueológicos sobre a dinâmica da ocupação da Amazônia Central anterior à colonização Brasileira.; Archaeometry is currently a well established field in the archaeological sciences. The nuclear method for analysis of chemical elements is one of the important instruments for the characterization of the archaeological materials and has influences on the preservation and restoration. From the chemical and physical analyses it is possible to infer technical processes in ceramics manufacture and tools used by ancient people. Therefore...

In this study, nine organic sediment samples from a medieval archaeological site at Pineuilh, France, were examined for Giardia intestinalis using two commercially available immunological kits [enzyme-linked immuno sorbent and immunofluorescence (IFA) assays]. Both techniques detected G. intestinalis in one sample, dated to 1,000 Anno Domini. This is the first time IFA was successfully used to detect protozoa in Old World archaeological samples. Such immunological techniques offer important perspectives concerning ancient protozoa detection and identification.

The aim of the present study was to examine the parasite fauna present in rodent coprolites collected from Cueva Huenul 1 (CH1), northern Neuquén (Patagonia, Argentina), an archaeological site that provides stratified sequences of archaeological and palaeontological remains dating from the Late Pleistocene/Early Holocene Transition to the Late Holocene period. Twenty rodent coprolites collected from different sedimentary units from the site, with ages ranging from 13.844 ± 75-1.416 ± 37 years BP, were examined for parasites. Each coprolite was processed as a whole: rehydrated, homogenised, spontaneously sedimented and examined using light microscopy. The coprolites and the eggs of any parasites present were described, measured and photographed. In all, 158 parasite eggs were found in 10 coprolites. The faeces were positive for Viscachataenia quadrata Denegri, Dopchiz, Elissondo & Beveridge and Monoecocestus sp. Beddard (Cestoda: Anoplocephalidae) and for Heteroxynema (Cavioxyura) viscaciae Sutton & Hugot (Nematoda: Oxyuridae). The coprolites examined were tentatively attributed to Lagidium viscacia Molina (Mammalia, Rodentia, Caviomorpha, Chinchillidae). The life cycles of these parasites are discussed.

AMS (Accelerator Mass Spectrometry) radiocarbon dates for eight potsherds from a single piece of pottery from a wetland archaeological site indicated that charred material from the inner pottery surfaces (5052 ± 12 BP; N = 5) is about 90 14C years older than that from the outer surfaces (4961 ± 22 BP; N = 7). We considered three possible causes of this difference: the old wood effect, reservoir effects, and diagenesis. We concluded that differences in the radiocarbon ages between materials from the inner and outer surfaces of the same pot were caused either by the freshwater reservoir effect or by diagenesis. Moreover, we found that the radiocarbon ages of carbonized material on outer surfaces (soot) of pottery from other wetland archaeological sites were the same as the ages of material on inner surfaces (charred food) of the same pot within error, suggesting absence of freshwater reservoir effect or diagenesis.

Palynomorphs extracted from the mud coffins and plant remains preserved at the archaeological site of Xiaohe Cemetery (Cal. 3980 to 3540 years BP) in Lop Nur Desert of Xinjiang, China were investigated for the reconstruction of the ancient environments at the site. The results demonstrate that the Xiaohe People lived at a well-developed oasis, which was surrounded by extensive desert. The vegetation in the oasis consisted of Populus, Phragmites, Typha and probably of Gramineae, while the desert surrounding the oasis had some common drought-resistant plants dominated by Ephedra, Tamarix, Artemisia and Chenopodiaceae. This present work provides the first data of the environmental background at this site for further archaeological investigation.

Preventive conservation requires monitoring and control of the parameters involved in the deterioration process, mainly temperature and relative humidity. It is important to characterise an archaeological site prior to carrying out comparative studies in the future for preventive conservation, either by regular studies to verify whether the conditions are constant, or occasional ones when the boundary conditions are altered. There are numerous covered archaeological sites, but few preventive conservation works that give special attention to the type of cover installed. In particular, there is no background of microclimatic studies in sites that are in the ground and, as in the Plaza de l’Almoina (Valencia, Spain), are buried and partially covered by a transparent roof. A large effect of the transparent cover was found by the sensors located below this area, with substantial increases in temperature and a decrease in the relative humidity during the day. Surrounding zones also have values above the recommended temperature values. On the other hand, the influence of a buried water drainage line near the site is notable, causing an increase in relative humidity levels in the surrounding areas. Multivariate statistical analyses enabled us to characterise the microclimate of the archaeological site...

The Noheda archaeological site is unique and exceptional for its size, and the quality and conservation condition of the Roman mosaic pavement covering its urban pars. In 2008 a tent was installed as protection from rain and sun. Being of interest to characterise the microclimate of the remains, six probes with relative humidity and temperature sensors were installed in 2013 for this purpose. Microclimate monitoring allowed us to check relative humidity differences resulting from the groundwater level, as well as inner sensors reaching maximum temperatures higher than the outdoors ones as a consequence of the non-ventilated tent covering the archaeological site. Microclimatic conditions in the archaeological site were deemed detrimental for the conservation of the mosaics. Thus, in summer 2013, expanded clay and geotextile were installed over the mosaics as a corrective action. The outcomes of this study have proven the effectiveness of this solution to control temperature and relative humidity, helping to configure a more stable microclimate suitable for preservation of the mosaic.

By means of radarfacies identification, this study aims to delimit the archaeological site and differentiate the coastal depositional systems that compose its substrates. For these purposes, available models of the temporal-spatial distribution of depositional systems in the area were used and sedimentological analysis (granulometry, quantification of heavy minerals and clay-mineral characterization) were performed on samples spaced at 0.5-m vertical intervals in auger drills cutting the identified radarfacies. GPR data were obtained along a radial grid, which allowed the rapid mapping of a large area (several hundred square metres). The results allowed to characterize an archaeological layer, the soil and two sedimentary layers (palaeolagoon and aeolian) in the substrates under and around the site. The high porosity and the grain size...

The site HLO1 in the Wadi al-Hilo, which means “Hilo river valley”, in the Emirate of Sharjah, UAE, has been excavated since 2007 by a Joint Project of the Directorate of Antiquities of the Government of Sharjah and the Institute of Pre- and Protohistory of Tübingen University under the direction of Sabah A. Jasim from the Sharjah side and Margarethe Uerpmann and Hans-Peter Uerpmann from the Tübingen side. The author was in charge of the actual excavations at the site from 2007 to 2012 and, under the supervision of Ernst Pernicka and Gregor Markl, of the evaluation of finds and findings presented in this dissertation. The site is situated near the upper end of the valley. Its name translates as “sweet valley”, which is due to its fertility and the rich supply of fresh water in its alluvial underground. Geologically, the area is dominated by Gabbro of the Oman–UAE Ophiolite, which contains small occurrences of copper ore. Some of them indicate traces of surface mining, including a locality at the northern periphery of the archaeological site. Indications for copper smelting at the site begin during the transition from the Neolithic to the Bronze Age. At present, this is the earliest proof for metallurgy in SE Arabia. Indications for continued occupation of the site during the Bronze and Iron Ages exist in the form of typical pottery from these periods. Direct and indirect evidence for metal production was found in the form of smelting furnaces...

The PoPaTERVA project is developing applied research regarding the comprehension of the multi-layered cultural background of the Terva Valley Archaeological Park, in Boticas, Portugal. One of the main aspects focused on the project is the appliance of remote sensing techniques to enhance non visible archaeological features. An earth resistance tomography (ERT) survey was carried out at the Sapelos hillfort, by the specialized SINERGEO geophysicist’s team, using a Wenner-Schlumberger array. The resulting data was analyzed by the authors in order to extract and verify valid archaeological features regarding the settlement’s structures. There are several adequate systems that can be used to visualize the surveyed data (x, y, z, Ω). However, the authors preferred the open source Visualization Toolkit (VTK) from Kitware Inc., since it supports several visualization and modelling techniques that are useful for interpretation purposes in archaeological contexts: for instance, it is possible to represent the archaeological site as a virtual scale model, which can be freely manipulated. For the Sapelos hillfort, two distinct visualizations were developed to represent the acquired electrical resistivity data. The first one is used to create a comprehensive volume from the surveyed data...

The archaeological site Cornesti "Iarcuri" is the largest earth fortification in Romania, made out of four concentric compounds, spreading over 1780 hectares. It is known since 1700, but it had only a few small attempts of systematic research, the fortress gained interest only after the publishing of some satellite images by Google Earth. It is located in an area of high fields and it occupies three interfluves and contains two streams. Our paper contains a geomorphologic, topographic and cartographic analysis of the site in order to determine the limits, the structure, the morphology, the construction technique and the functionality of such a fortification.Our research is based on satellite image analysis, on archaeological topography, on soil, climate and vegetation analysis as a way to offer a complex image, through this interdisciplinary study of landscape archaeology. Through our work we try not to date the site as this objective will be achieved only after completing the systematic excavations which started in 2007, but only to analyze the co-relationship with the environment.; Comment: 14 pages, exposed on 5th International Conference "Actualities and Perspectives on Hardware and Software" - APHS2009, Timisoara, Romania

This is the final version of the article. It was originally published in the Journal of Archaeological Science, Volume 55, March 2015, Pages 122?134, doi: 10.1016/j.jas.2015.01.001; Radiocarbon date frequency distributions and archaeological site counts are two popular proxies used to investigate prehistoric demography, following the assumption that variations in these data reflect fluctuations in the relative size and distribution of past populations. However, the two approaches are rarely applied to the same data-set and their applicability is heavily conditioned by the archaeological record in question, particularly research histories, agendas, and funding availability. In this paper we use both types of data to examine the population history of the Upper Palaeolithic hunteregatherers (~40 000e12 000 cal BP) of Southwestern France, comparing the demographic signatures generated. Both proxies produce similar signatures across the Upper Palaeolithic sequence of the region, strengthening the interpretation of relative demographic changes as the cause of the pattern. In particular, a marked population decline is seen in both datasets during the Late Gravettian (~28 000 cal BP), as well as a population increase in the Late Solutrean (~25 000 cal BP) supporting the notion that the region acted as a population refugium during the Last Glacial Maximum. Where the two proxies diverge in the demographic signatures they produce...

The HMS Swift was a British Navy sloop-of-war that sank off the Patagonia coast in 1770. The Swift shipwreck site, on the northern coast of Santa Cruz Province (Argentina), is a well-preserved underwater archaeological site. The high frequency of wooden artifacts at the site permitted the development of specific research designed to identify the primary natural and cultural post-depositional processes related to the preservation and spatial distribution of those artifacts. This paper presents the methodological framework for this research, which included both direct observations and experimental studies that led to the characterization of the organisms related to the shipwreck site and their interaction with archaeological materials. Results confirm that sedimentary conditions have played a central role in the preservation of wooden materials and their spatial distributions. Furthermore, the archaeological consequences of organisms' damaging activities (mainly those of marine wood-borer mollusks) are assessed.
