AN EVALUATION OF ANALYTICAL AND INTERPRETATIVE METHODOLOGIES FOR THE EXTRACTION AND IDENTIFICATION OF LIPIDS ASSOCIATED WITH POTTERY SHERDS FROM THE SITE OF SAGALASSOS,TURKEY*

Three lipid analysis methods were applied to extracts of archaeological potsherds from the ancient city of Sagalassos, south‐west Turkey. In the fatty acid methyl ester fraction, obtained by selective transesterification of acylglycerols, the ratio of methyl palmitate to methyl stearate was determined. Secondly, by means of gas chromatography– combustion–isotope ratio mass spectrometry (GC–C–IRMS), stable carbon isotope ratios were measured for the same methyl esters. Finally, triglyceride composition was determined via high‐performance liquid chromatography–mass spectrometry (HPLC–MS). All three methods can be used to trace the origin of animal fat. Agreement between them is reasonable, especially in recognizing ruminant adipose fat. One sample was found to be of dairy origin using both GC–C–IRMS and HPLC–MS. The advantages of the various methods are discussed. Variations in lipid composition were observed between samples from different periods and excavated in diverse areas within the city of Sagalassos.     

PURPLE-DYE PRODUCTION IN LYCIA – RESULTS OF AN ARCHAEOZOOLOGICAL FIELD SURVEY IN ANDRIAKE (SOUTH-WEST TURKEY)

Summary.   In 2003 a substantial deposit of heavily fragmented shells of purple snails was by chance located at the site of Andriake, the ancient port of the Lycian city of Myra near Demre, in southern Turkey. The archaeozoological and archaeological record of a survey project in 2004 proved the identification of a large installation for the production of purple dye. Adjacent to a well preserved Hadrianic granary and partly superimposing the remains of a U-shaped building, the deposit is wrapped around three sides of a subterranean cistern. Apparently dating to the sixth century AD, the deposit contains approximately 300 m³ of shell debris. The unique chance of examining an undisturbed and well preserved manufacturing place for purple dye provides an excellent opportunity to investigate the processual particularities as well as the ecological impact of purple-dye production in antiquity.     

ELECTRON SPIN RESONANCE STUDY OF WHITE MARBLES FROM THARROS (SARDINIA): A REAPPRAISAL OF THE TECHNIQUE,POSSIBILITIES AND LIMITATIONS*

The characterization of various samples of white marble from the archaeological site of Tharros (Sardinia) is the starting point for the reexamination of the capabilities of electron spin resonance (ESR) spectroscopy as a tool for identifying the quarries of origin of ancient marble artefacts. Existing methods and data bases are employed for the assignment of our samples, but also reviewed to see if a more extensive use of the technique is feasible. It turns out that ESR spectroscopy, coupled with other available methods, may readily provide valuable information, often yielding the final answer to the problem of marble provenance. However, it is also clear that much work has still to be done to standardize the data collection and analysis procedures and to expand the available data base.     

TRACING THE RESOURCES OF IRON WORKING AT ANCIENT SAGALASSOS (SOUTH‐WEST TURKEY): A COMBINED LEAD AND STRONTIUM ISOTOPE STUDY ON IRON ARTEFACTS AND ORES*

Lead and strontium isotope analyses were performed by thermal ionization mass spectrometry (TIMS) on Roman to Byzantine iron artefacts and iron ores from the territory of ancient Sagalassos (south‐west Turkey), to evaluate Pb and Sr isotopes for provenance determination of ores for local iron production. It can be demonstrated that for early Roman artefacts and hematite iron ore processed in early Roman times from Sagalassos proper, as well as for magnetite placer sands and early Byzantine raw iron from the territory of the city, Sr isotopes are much less ambiguous than Pb isotopes in providing clearly coherent signatures for ore and related iron objects. Late Roman iron objects were produced from iron ores that as yet remain unidentified. Early Byzantine iron artefacts display more scatter in both their Pb and Sr isotope signatures, indicating that many different ore sources may have been used. Our study demonstrates that iron objects can be precisely analysed for their Sr isotopic composition, which, compared to Pb isotopes, appears to be a much more powerful tool for distinguishing between chronological groups and determining the provenance of raw materials.     

THE CHARACTERIZATION OF PAINTS AND WATERPROOFING MATERIALS FROM THE SHIPWRECKS FOUND AT THE ARCHAEOLOGICAL SITE OF THE ETRUSCAN AND ROMAN HARBOUR OF PISA (ITALY)*

This work presents the results of a diagnostic survey on the shipwrecks from the archaeological site of the ancient harbour of San Rossore (Pisa, Italy). The original waterproofing, caulking and painting materials were characterized by Fourier transform infrared spectroscopy (FTIR), gas chromatography – mass spectrometry (GC–MS), energy‐dispersive X‐ray microanalysis (EDX) and X‐ray diffraction (XRD). The major constituents of the waterproofing and caulking materials detected on the planks were tricyclic abietanes showing a high degree of aromatization. These compounds are indicative of a pitch obtained from the wood of trees of the Pinaceae family. The analysis of the organic components of the paint samples revealed diterpenoid acids characteristic of Pinaceae resins together with linear long‐chain alcohols and fatty acids, highlighting the presence of beeswax. Noticeably, the characteristic odd carbon number alkanes that are normally present in beeswax were not detected. The EDX and XRD analyses showed that hematite, calcite, cerussite and kaolinite were employed as pigments to paint the ships’ hulls.     

ARCHAEOLOGICAL VOLCANIC GLASS FROM THE SITE OF ROCCHICELLA (SICILY,ITALY)*

The site of Rocchicella, near Catania, in eastern Sicily, has yielded important archaeological evidence from prehistoric times to the Middle Ages. Extensive archaeological investigations of cultural layers dating from the Palaeo‐Mesolithic to the Copper Age have recently been undertaken, and volcanic glass, mainly obsidian, has been collected in the course of excavation. To determine the provenance of this volcanic glass, a non‐destructive elemental analysis was carried out to measure the concentration of characteristic trace elements. The analysis was carried out using a new XRF spectrometer equipped with a beam stability controller and a quantitative method developed at the LANDIS laboratory of the INFN–CNR Institutes of Catania. In addition to the obsidian, it was demonstrated for the first time that a local vitreous material similar to obsidian, but displaying a completely different composition, was used during all the investigated periods. This material was identified as a basaltic glass, characterized by a superficial product of devitrification called palagonite. Analysis of the obsidians has led to the identification of the island of Lipari as the provenance source. High‐ and low‐power microscopic use‐wear analysis on obsidian and basaltic glass artefacts indicated that soft wood and plant matter might have been processed at the site.     

OPTICAL DATING OF ANTHROPOGENIC SEDIMENTS AT THE ARCHAEOLOGICAL SITE OF HERRENBRUNNENBUCKEL,BRETTEN-BAUERBACH (GERMANY)*

Optical dating was applied to natural and anthropogenic silts at an Iron Age settlement in southern Germany. The natural sediments were dated accurately and allowed study of the human impact on the landscape. The studied anthropogenic sediments were infills of cellars and ditches. Again, deposits derived from soil erosion proved to be datable using infrared-optically stimulated luminescence. However, optical dating of fine grained sediments was at its limits when sediments consisted of a mixture of bleached and unbleached grains. This is shown on sediments of known age originating from cellar infills. Improvements were obtained when using the 560 nm emission and a partial bleach approach. Experimental evidence shows that the D_E versus shine-time plot discloses insufficient bleaching only in cases in which all grains are insufficiently bleached to the same degree.     

MULTISENSOR GEOPHYSICAL SURVEY RESULTS FROM THE PINE TREE MOUND SITE: A COMPARISON OF GEOPHYSICAL AND EXCAVATION DATA

Abstract

A multisensor geophysical investigation of portions of the Pine Tree Mound site (41HS15) located in Harrison County, Texas, was conducted prior to large-scale block excavations there. The investigation included electrical resistance, magnetic field gradient, and ground-penetrating radar surveys. The geophysical survey and subsequent excavations were undertaken in an effort to mitigate the effects of coal mining operations on the site. This article presents the results of our geophysical investigations and describes an online data analysis tool created with the intention of simplifying interpretation of these complex multivariate data and making these data available to a broad audience. The article also compares the geophysical signal response with excavation results from the site. Sources of uncertainty in both data sets are discussed, and possible reasons for observed incongruities between the geophysical and excavation data are explored. We end by making recommendations for innovative ground truthing methods that might allow us to more definitively interpret geophysical data in the future.     

GEOPHYSICAL AND ARCHAEOLOGICAL INVESTIGATIONS AT THE CLEMENT SITE,A CADDO MOUND COMPLEX IN SOUTHEASTERN OKLAHOMA

Abstract

Since the 1960s, few professional archaeological excavations have been conducted at Caddo sites in southeastern Oklahoma. This article summarizes the initial phase of a research program designed to increase our knowledge of this area. Geophysical and archaeological investigations at the Clement site (34Mc8) were conducted during the summer of 2008 by the University of Oklahoma. These revealed deep middens, intact mound stratigraphy, and architecture, and suggest that Clement had multiple Caddo occupations spanning approximately 300 years.     

THE GEOCHEMISTRY OF THE MAJOR SOURCES OF ARCHAEOLOGICAL OBSIDIAN ON HOKKAIDO ISLAND (JAPAN): SHIRATAKI AND OKETO

The geochemical compositions for obsidian from two of the most important sources on the Japanese island of Hokkaido, Shirataki and Oketo, are presented. This work represents the first systematic study of obsidian geochemistry on Hokkaido from the view of modern methodological standards. The study was performed with the help of neutron activation analysis to determine the concentrations for 28 elements. The results obtained allow us to subdivide both sources into two geochemical groups (Shirataki‐A and ‐B; and Oketo‐A and ‐B), with each representing an individual sub‐source. Obsidian from both Shirataki and Oketo sources is identified at archaeological sites located on Hokkaido, on the neighbouring Sakhalin Island and Kurile Islands, and in the lower course of the Amur River basin. The distance of obsidian transport during the Upper Palaeolithic was up to ～250 km, and in the following Neolithic and Palaeometal periods up to ～1200 km. This testifies to the wide distribution of Hokkaido obsidian to archaeological complexes in North‐East Asia and its active transport/exchange in prehistory. The data presented here should be used as a reference for the obsidian geochemistry of Shirataki and Oketo sources from now on.     

A TOWN AT THE CROSSROADS: SITE-WIDE GRADIOMETRY SURVEYING AND MAPPING AT OLD TOWN RIDGE SITE (3CG41) IN NORTHEASTERN ARKANSAS

Abstract

Gradiometry survey at the Old Town Ridge (3CG41) site, a stockaded Middle Mississippian period town in the central Mississippi River Valley of Arkansas, demonstrates the efficacy of a broad-coverage, site-encompassing remote sensing methodology for initial interpretation of intrasite organization and complexity. Site access, time constraints, deep plow furrows, and cotton plant “stubble” associated with ongoing agriculture at the site defer the efficient use of a site-wide multisensor prospection methodology. However, a gradiometry survey identified multiple anomalies consistent with prehistoric structures, earthworks, earthquake liquefaction, and other interpreted features encompassed within the remains of a 7-ha, rectangular enclosure. Aerial photography, topography, and preliminary archaeological ground truthing provided additional information for analysis and interpretation.     

THE FIRST ARCHAEOMETRIC CHARACTERIZATION OF ROMAN MILLSTONES FOUND IN THE AQUILEIA ARCHAEOLOGICAL SITE (UDINE,ITALY)*

An archaeometric study of all the Roman millstones preserved today in the National Archaeological Museum of Aquileia, the ancient capital of the X Regio Augustea –‘Venetia et Histria’ located on the Friuli plain (northeastern Italy), has been recently envisaged to define their geological–geographical provenance. We present here the results of the first step of the research, which is aimed at characterizing all of the definitely allochthonous lithologies. In order to carry out petrography on thin‐section and geochemical analyses, 10 small samples were picked out directly from Pompeian‐style millstones (catilli and/or metae) and rotary querns. Five different lithologies originating in various Italian regions were recognized: eight samples consist of pale‐ and dark‐grey lavas from the Venetian Volcanic Province, Vulsini Volcanic District (Latium), Etna Volcano and Pantelleria island (Sicily), whereas two samples were shown to be made of green garnet‐bearing schists (pietra ollare) from the Western Italian Alps. The presence of Alpine pietra ollare in northeastern Italy, used to produce pots and food containers, was established for numerous classical findings at Roman and Middle Age sites, but the analysed items represent the first evidence for the utilization of this kind of stone to produce mills during the Roman epoch.     

THE DEVELOPMENT OF NEOLITHIC AND COPPER AGE SETTLEMENT IN THE GREAT HUNGARIAN PLAIN PART II: SITE SURVEY AND SETTLEMENT DYNAMICS

Summary. Within the region of the Great Hungarian Plain (discussed in the first part of this article) the processes of settlement change can be followed in greater detail from site survey in the Szeghalom area. This central part of the Plain, drained by the Körös and Berettyó rivers, was a major focus of settlement in Neolithic times (6000-4000 BC), and its rising importance can be followed in the emergence of a series of wealthy 'supersites'. During the succeeding Copper Age, the character of sites altered as the role of the area in relation to the rest of the region began to change. Around 3500 BC a dramatic shift in settlement patterns coincided with the appearance of large tumuli of steppe type, which mark a new phase of land use in this region.     

NETWORK EQUILIBRIUM MODELS OF URBAN LOCATION AND TRAVEL CHOICES: A RETROSPECTIVE SURVEY*

ABSTRACT The origins and development of the network equilibrium problem are traced and interrelated. Two principal formulations are considered the network equilibrium problem with variable travel demand, and the combined model of trip distribution and traffic assignment. The relation of these models to subsequent developments concerning mode choice, residential location, estimation of origin-destination tables from link flows and stochastic route choice are then reviewed.

EMBEDDEDNESS AND THE (RE)MAKING OF RETAIL SPACE IN THE REALM OF MULTICHANNEL RETAILING: THE CASE OF MIGROS SANAL MARKET IN TURKEY

The purpose of this article is to investigate the value of the concept of embeddedness for economic geographers. Alongside the case study of the multichannel grocery retailing brand Migros in Turkey, the spatial impacts – in relational and physical terms – of digitalization and the integration of an online shop into the profile of a supermarket chain are investigated. In applying the concept of embeddedness the article seeks to understand these complex, diverse and uneven processes of (retail) restructurings that affect different dimensions and dynamics of networks, societies and spaces. In my case study I identify two dimensions of embeddedness processes: (1) embedding the online shop in the firm's routines and practices, whereby processes of transfer of knowledge and technology dominate; and (2) embedding online shopping in the customer's routines and practices, whereby processes of adaption to consumer culture dominate. These dimensions are reflexive and as such mirror ongoing negotiation processes between the two stakeholders. On one hand multichannel retailing thus not only alters where but also how people shop, and can result in new retail spaces like pick‐up stores. On the other hand it can be shown, that the “locations”, where online shopping of Migros is available, reproduce spatial variations of socio‐economic factors, such as income distribution or population density. As such, the concept of embeddedness is useful for economic geographers – also in the realm of e‐commerce – to unravel the interconnections of societal, organizational and spatial patterns as well as their variations across space. The study is based on qualitative interviews.

PHOSPHORUS ANALYSIS AT ARCHAEOLOGICAL SITES: AN OPTIMIZATION OF THE METHOD AND INTERPRETATION OF THE RESULTS

The application of phosphorus analysis to archaeological contexts can be considerably improved through ultrasonic extraction and the statistical evaluation of results through an analysis of variance. Such tools make the archaeological application of phosphorus analysis faster as well as more economical and coherent. This paper describes the features of these tools and provides a practical case: the Late Neolithic—Early Copper phase of the site ‘Polideportivo’in Martos, southern Spain.
