The design of effective and efficient trial trenching strategies for discovering archaeological sites

This paper reports a study on the effectivity and efficiency of trial trenching strategies for site discovery within the context of Dutch archaeological heritage management. It discusses the principles of site discovery by means of trial trenching, and suggests the optimal strategies for trial trenching survey, based on the results of simulations. Effective and efficient strategies for discovering different groups of archaeological sites are given, according to their presumed size, shape and feature density. The recommended strategies will be included in the Quality Norm for Dutch archaeology.

Surveys and Mesoamerican Archaeology: The Emerging Macroregional Paradigm

This article is a review of regional archaeological surveys in Mexico, emphasizing published full-coverage surveys from the last 20 years. The geographic focus is non-Maya Mexico terminating at the Tropic of Cancer. The temporal focus is the 3000-year period from the earliest settled villages to the Spanish conquest (A.D. 1521), with emphasis on long-term evolutionary trajectories. The main argument is that explanations of regional-scale settlement patterns are proving to be incomplete now that archaeologists are confronted with site distributions on the macroregional scale. Implications of the emerging macroregional paradigm are discussed for current debates in Mesoamerican archaeology.     

The implications of water storage for human settlement in Mediterranean waterless islands: The example of Pantelleria

Abstract

Consistent water supply is a common issue in the history of Mediterranean civilizations, where hydraulic solutions, such as cisterns, wells, reservoirs and aqueducts, were adopted for private and public supply. In this context, the island of Pantelleria, where surface freshwater is virtually non-existent, represents a unique case for understanding human–environment interaction in waterless environments. Here, in historical times, year-round water supply was only possible through the storage of rainwater in underground cisterns. An intensive field survey carried out across the island led to the discovery of hundreds of cisterns dated from the Punic and Roman periods to the present day. The study of the spatial distribution of the cisterns was compared with archaeological data on the island to gain new insights on historical settlement and demographic patterns. The present work focusses on a semi-quantitative assessment of water storage on the island of Pantelleria based on the evaluation of potential volumes of stored water for different periods. Data available for cisterns in Pantelleria have been analysed and compared with those from coeval Mediterranean regions. Calculations on the seasonal fluctuation between water demand and supply have been estimated to evaluate the efficiency of such system for sustaining human population and subsistence activities through time.     

Establishing discovery probabilities of lithic artefacts in Palaeolithic and Mesolithic sites with core sampling

This paper reports the results of a study into the effectiveness of core sampling for discovering Palaeolithic and Mesolithic hunter-gatherer sites in the Netherlands and northwestern Belgium. Earlier work established optimal sampling strategies for use in archaeological heritage management survey in the Netherlands. However, the statistical model used for this was based on a limited amount of data on the distribution of lithic artefacts in Palaeolithic and Mesolithic sites. For the current study we have analyzed the distribution of artefacts in a selected number of excavated sites, and estimated discovery probabilities of these sites through simulation. The simulation results indicate that discovery probabilities are lower than expected due to the effect of clustering of finds. Furthermore, the density of flints in Palaeolithic and Mesolithic sites is generally lower than the estimates that were used for setting up the optimal sampling strategies, and a substantial number of sites is very small. This means that, in order to discover Palaeolithic and Mesolithic sites with sufficient reliability, we will have to apply more intensive survey strategies than have been recommended up to now.     

The use of an improved pRIA technique in the identification of protein residues

Blood and protein residue identification in archaeological research has been a controversial subject for the last 20 years. This paper reports on the use of an improved protein radioimmunoassay (pRIA) technique in identifying protein residues. Results from the blind testing of the original and improved pRIA techniques in identifying bloodstains on experimental lithic artifacts are described and compared. We argue that the improved pRIA technique is highly sensitive and accurate for identifying protein residues to genus, and thus has excellent applications for archaeological research.     

UAV and RPV systems for photogrammetric surveys in archaelogical areas: two tests in the Piedmont region (Italy)

Aerial photogrammetric surveys are usually expensive and the resolution of the acquired images is often limited. For this reason, different innovative systems have been developed and tested in order to perform a photogrammetric survey in an inexpensive way, with high-resolution images. In this context, one of the most promising acquisition techniques is represented by the use of Unmanned Aerial Vehicles (UAVs) equipped with a digital camera.     

Modelling spatial heterogeneity and nonstationarity in artifact-rich landscapes

In this paper we consider a crucial issue for survey archaeology: how we identify and make sense of the heterogeneous and often inter-dependent behaviours and processes responsible for apparent archaeological patterns across the landscape. We apply two spatial statistical tools, kriging and geographically weighted regression, to develop a model that addresses the spatial heterogeneity and spatial nonstationarity present in the pottery distributions identified by our intensive survey of the Greek island of Antikythera. Our modelling results highlight a clear spatial structure underlying different scales of pottery density as well as locally varying relationships between pottery densities and several environmental variables. This allows us to develop further testable hypotheses about long-term settlement and land-use patterns on Antikythera, including more explicit models of community organisation, and of the relationship between the island's geomorphological structure and its history of past human activity.     

The Landscape Archaeology of Southwest Sardinia Project: New Data and Method from the Insular Mediterranean

Sardinia has played a vital integrative role in the Holocene Mediterranean, most notably—although not only—as a key locus in emergent maritime “Mediterraneanization” and as an object of contestation among mainland polities over the last three millennia. Yet, despite the florescence of Mediterranean survey archaeology, this standard method has only been sparsely employed in Sardinia, with a pronounced focus on large, urban, coastal sites. Accordingly, we have little understanding of the ebb and flow of human settlement in the Sardinian interior. This represents a significant lacuna in the study of Mediterranean archaeology and history. Here, we report data from the first two seasons of the Landscape Archaeology of Southwest Sardinia (LASS) Project, a multidisciplinary project designed to correct this bias and to investigate how episodic integration into—but also disintegration from—larger economic and political structures drove sociocultural and socioeconomic change in southwestern Sardinia over the Mid-Late Holocene.     

前视全景钻孔电视在龙门石窟防渗工程中的应用

影响龙门石窟雕刻艺术品长期保存的主要病害是渗水,卸荷裂隙往往切割洞窟、隙宽较大而成为洞窟渗水的主要通道。为查明洞窟卸荷裂隙的分布位置,最可靠的方法是在现场进行水平钻探。但受钻探施工的干扰,钻孔岩芯可能在钻探取芯的过程中造成折断或破裂,钻孔取芯率也会相对较低,因而仅靠观测岩芯难以确定卸荷裂隙的准确部位。为此,采用有潜在价值的钻孔电视方法,以识别不同的岩层,确定裂隙的分布情况及裂隙中的充填物。研究结果表明钻孔电视在龙门石窟防渗工程中取得成功的应用,说明这是一种值得在岩土文物保护工程中推广应用的新技术。     

Satellite imagery and archaeology: the example of CORONA in the Altai Mountains

Satellite imagery, and specifically CORONA, is now of common use in archaeology. CORONA, as it produces two images of the same spot (afterward and forward), allows for stereoscopic view and is a perfect tool for the production of maps, especially in remote areas, where maps are not reliable of even absent.     

The spatial distribution of Palaeolithic human settlements and its influence on palaeoecological studies: a case from Northern Iberia

The aim of this study is to assess the influence of human site location choice on biogeographical and paleoecological studies based on archaeological remains, through a case study in north-western Spain. Data from an exhaustive literature survey and field trips were managed with GIS and subjected to statistical analyses. The results show that the influence of the different variables shifted through the Palaeolithic, although certain general preferences can be seen: low altitudes (median: 151 m a.s.l.), South-facing surfaces, generally gentle slopes (median: 13°) and moderate distances to water courses (median: 297 m). These choices were conditioned by geomorphological factors, with LGM glacier extent imposing an upper limit in the range of occupied altitudes and marine and fluvial terraces conditioning site location patterns. The results suggest that human site location patterns during the Palaeolithic were not random, conditioning the information available from archaeological remains. Our results allow us to identify some key areas where information on past faunal distributions, and more generally on biocoenoses, will be scarce or missing.     

Combined application of pansharpening and enhancement methods to improve archaeological cropmark visibility and identification in QuickBird imagery: two case studies from Apulia,Southern Italy

Launch of Very High Resolution (VHR) satellite sensors meant a significant evolution for Remote Sensing archaeological applications since data with high spatial resolution may be used to identify signals related to buried archaeological remains (e.g. cropmarks, soilmarks, dampmarks) in very extended territories. The aim of this work is to develop a suitable image processing workflow to improve the cropmark visibility in the VHR satellite images. The workflow implemented consists of two steps: first the panchromatic and multispectral images have been pansharpened in order to merge the two images, then some Enhancement methods have been applied on the pansharpened image. As a result of the several tested pansharpening techniques, the Principal Component Resolution Merge yields images of very good quality useful not only for visualization but also as input for further processing. Among the different enhancement methods taken into consideration, the Spatial Enhancement, carried out by applying the Wallis Adaptive filter further improve the visibility and recognition of the archaeological signals.     

The Azazo Project: Archaeology and the Community in Ethiopia

Abstract

In this article we discuss the motivations, aims, and preliminary results of working with a local community in Ethiopia. Trying to escape from the (neo)colonial archaeology that is still practised in Africa, this project aims to achieve a cooperative and participative archaeology. This work with the community has been one of our main priorities in our last seasons, and although we have focused on elementary school and university students, we have opened up a number of different paths to follow in future years. The experience has been very positive, and engagement with local people has helped us to create awareness about the importance of cultural heritage, hopefully ensuring the future protection of the sites.     

Spatial and temporal variety of prehistoric human settlement and its influencing factors in the upper Yellow River valley,Qinghai Province,China

We report an investigation of forty-two prehistoric sites in the upper Yellow River valley located in Guide, Jianzha, Hualong, Xunha and Minhe, Qinghai Province, China, including forty-four new radiocarbon dates from twenty-four sites, review published archaeological surveys and radiocarbon dates, analyze landform features and discuss the reasons for spatial and temporal variety of regional prehistoric human settlement. Our results suggest that people occupied the upper Yellow River valley during the early Holocene, but a continuous archaeological record begins only after about 5500 Cal yr BP. Thereafter, the intensity of prehistoric human settlement in the area is varied. Neolithic human settlement spread northwestward to high altitude areas of the upper Yellow River valley during early-mid Majiayao and Qijia periods, but moved southeastward to lower locations in the area during late Majiayao period. During the Bronze period, two coeval archaeological cultures, the Kayue and Xindian, occupied the upper Yellow River Region. Kayue archaeological sites are numerous and widely distributed in the high areas of the upper Yellow River, while Xindian sites are restricted to the lowest basin of the region. Variation in site density and location are likely the result of changing paleoclimate and technology.     

Liangzhu and Centennial Archaeology: The Underestimated Neolithic Age in China

The discovery in Yangshao, Mianchi, Henan in 1921 marked the beginning of modern Chinese archaeology. Nowadays, Chinese archaeology has gone through a full 100 years. Through the hard work of generations of archaeologists, Chinese archaeology has achieved sustained growth and development. Chinese archaeology has been advancing for a century and has made great contributions to the construction of Chinese history and culture. Archaeology has important practical significance in contemporary times. Archaeological exploration is not limited to discovering the past, but also lies in the thoughts of gazing at history in the current context. Chinese archaeology in the new era is committed to integrating the spirit of this discipline into cultural construction and social life, so as to learn the new by reviewing the past. After more than 80 years of archaeological exploration, many large tombs of the Liangzhu culture were discovered one after another, mainly including burial of jade, from the 1970s to the end of the 1980s. The ritual jade artifacts such as cong (a long hollow piece of jade with rectangular sides) and bi (jade disk), as well as the differences in the levels of tombs, all reflect the high development of Liangzhu society. The ancient city of Liangzhu was discovered in 2007, and the water conservancy system was confirmed in 2015, pushing the Liangzhu culture to the height of national civilization. In 2019, the Archaeological Ruins of Liangzhu City was listed as a World Heritage site.     

The objective–subjective dichotomy and its use in describing probability

ABSTRACT

This article reviews the nature of the objective–subjective dichotomy, first from a general historical point of view, and then with regard to the use of these terms over time to describe theories of probability. The different (metaphysical and epistemological) meanings of ‘objective’ and ‘subjective’ are analysed, and then used to show that all probability theories can be divided into three broad classes. A formal definition of (epistemological) objectivity is given and used to clarify this division.     

Mineral weathering in forest soils and its relevance to the preservation of the buried archaeological resource

There is more woodland in Britain now than for many centuries and considering many international climate change mitigation policies, woodland cover, both in Britain and internationally, is being promoted. However, neither the management of existing woodlands nor their expansion should be at the expense of important archaeological evidence. Due to the large number of known archaeological sites, the large areas of land with uninvestigated archaeological potential and the expanding woodland cover, suitable mitigation strategies need to be developed to allow preservation in situ of important sites. An understanding of how woodland soils and the buried archaeological resource interact is, therefore, essential. This paper utilises ongoing environmental research into the mineral weathering rates in forest soils and considers its application to artefact preservation. The study concludes that soil water pH, its movement, and the saturation of dissolved ions in the soil solution are major factors determining both mineral and artefact longevity. A simple guide to artefact longevity based on these properties is proposed and a geochemical model for predicting loss is tested. These tools could be applied to any soil or individual horizon irrespective of land-use.
