The Silversmith's Workshop of Tira Del Lienzo (Totana,Murcia) In The Context of Iberian Bronze Age Metallurgy

The south‐east of the Iberian Peninsula saw deep social and political changes at the dawn of the second millennium bce . The emergence of important economic asymmetries inside communities was apparently based to a large extent on control of the secondary metallurgical production process; namely, forging. In this sense, the recently excavated architectural complex at the Argaric site of Tira del Lienzo constitutes an exceptional finding. At this site a series of macrolithic artefacts were recorded, which were related to the forging of metals and, more specifically, to the working of silver, according to morpho‐technological and functional studies (use‐wear and residue analysis).     

Mapping Mesolithic and Neolithic cultures behaviours and interactions with nature and properties of rocks in Western France

Multivariate statistical methods are used to study recent Prehistory lithics from the Armorican Massif, allowing us to classify them in more or less distinct groups according to the structural and mineralogical qualities of rock types involved. Analyses are carried out on metamorphic, sedimentary and magmatic rocks making up lithics collected from 31 localities. The petrographic properties are determined by polarizing microscope (POM), while the mechanical properties are obtained by Vickers's indentation method (VI), compression/traction (CT) and ultrasound echography (UE). The results provide us with important information about the management of lithic raw materials used by various human and cultural groups during the Mesolithic and Neolithic of the Armorican Massif. The more commonly used materials show a homogeneous and stable distribution of regional technology styles. The rock types exhibiting mature and homogeneous structures possess the better qualities for knapping (fracture energy G_Ic) and use (edge toughness M₁), and are more involved in exchange. The application of Upward Hierarchical Classification (UHC) and Principal Component Analysis (PCA) allows us to identify the classes of materials as well as the causes of variations of rock type abundance within the lithic assemblages of the Mesolithic and the Neolithic. In this way, we can then also predict the discovery of archaeological artefacts in areas lacking any known indications of the exploitation of outcropping materials.     

THE MATERIALS OF HOYSALA TEMPLES AND SCULPTURES: A PETROGRAPHIC CHARACTERIZATION

Talcxhlorite schist is the material commonly used by the sculptors and builders of the Hoysala dynasty, which ruled i n the western part of India south of the Deccan from the eleventh to the mid-fourteenth century. Forty-one samples from seven Hoysala sites were examined by petrographic microscopy and electron beam microprobe analysis. Although it is difficult to distinguish between some of the rocks from the different sites. many contain minerals that can be valuable in distinguishing between different possible quarry sources.     

INTERPRETING THE SOCIAL MEANING OF DIFFERENT SHAPES OF HOUSE STRUCTURES BY EXAMINING THE FLOW OF RESOURCES: A CASE STUDY OF SAQACENGALJ AT THE SOUTHERN TIP OF TAIWAN

Social differentiation is characterized by differences in social status and wealth, which are established and maintained by controlling and constraining the labour and flow of resources. This would affect the development of various aspects of a settlement in establishing hierarchical relationships. This study focuses on identifying the variations in the distribution of certain resources, such as imported goods, that help interpret the social meaning, particularly with regard to social status and wealth, of house structures having different shapes in an ethnic settlement in Taiwan. A petrographic study and residue analysis of the pottery along with spatial examination of the material remains were conducted to achieve the goal.     

Archeometric characterization of prehistoric grindstones from Milazzo Bronze Age settlement (Sicily,Italy)

The results of a petrographic and geochemical study carried out on archeological grindstones allow to provide new constraints on protohistoric commercial exchanges over the Mediterranean area. Eleven grindstones, discovered in an archeological site located in Milazzo (Messina, Sicily) and dated from the Early Bronze Age, have been investigated by geochemical and petrographic techniques. The raw materials are mainly volcanic rocks characterized by calc-alkaline and K-alkaline affinities with volcanic arc geochemical signature. Only one sample, made of basalt belonging to the Na-alkaline series, shows an intraplate signature. The comparison with the available literature data for similar rocks allowed constraining the volcanic origin of the exploited lavas. While the intraplate-type raw material came from Mt. Etna Volcano (Sicily), the arc-type volcanic rocks are mostly trachyandesites, basaltic andesites, and one rhyolite. Although most of them come from the Aeolian Arc, a provenance of some samples from the Aegean Arc cannot be excluded. This last region could represent the most probable provenance area for the rhyolite sample.     

Raw material availability,flaking quality,and hunter–gatherer technological decision making in northern Tierra del Fuego Island (southern South America)

The technological organization and lithic raw material procurement of Holocene hunter–gatherers have been topics of considerable interest in northern Tierra del Fuego Island. Ongoing archaeological investigations indicate that most of the rocks employed by native human populations came from secondary deposits of fluvio-glacial and marine origin. However, a primary geological source for two distinctive lithologies has been recently discovered near the Chorrillo Miraflores Valley (Tierra del Fuego, Chile). These raw materials became the focus of further research since one of them (a silicified tuff) has been identified in several archaeological sites of Tierra del Fuego. Some of these sites are located more than a hundred kilometers away from the source. A regional survey of potential lithic sources along with petrographic and geochemical analyses confirmed that the silicified tuff is only available at Chorrillo Miraflores. Here we present the technological analysis of artifacts manufactured on Miraflores silicified tuff that were recovered from the Argentine portion of northern Tierra del Fuego composed of Espíritu Santo and San Sebastian Capes. The role of utilitarian currencies in the prehistoric use of this lithology is assessed through the application of the Metcalfe and Barlow (1992) field processing model. The results show that this raw material may not have been exclusively selected for its flaking quality, although an alternative functional efficiency hypothesis is also introduced. Finally, its spatially restricted availability as well as unique macroscopic aspect suggests its selection and use may have been mainly influenced by social factors.     

战国秦汉时期制铁耐火材料的矿物组织与含量分析

战国秦汉时期是中国古代生铁与生铁制钢技术体系的发端与形成期,制铁耐火材料为发达的生铁与生铁制钢技术体系提供了结构、化学、热性能上的技术保障,具有重要的作用。但目前制铁耐火材料的研究较少,影响了对中国古代钢铁技术的全面认识。本研究对战国秦汉时期出土的制铁耐火材料开展了文献、田野考察和矿相分析,科学认知其微观结构,认为战国秦汉时期制铁耐火材料以黏土质材料为主,使用了砂质材料,但尚未出现砂泥混合质材料。同时,炉壁、铸铁范、鼓风管之间的矿物显微组织和含量差异较大,表明战国秦汉时期工匠已能根据性能需求的不同制作不同的耐火材料用于不同的制铁生产环节。     

Contribution to the geology of Failaka Island,Kuwait: Evidence from sedimentological and petrographic data from the NE part of the island

Kuwait–Georgian archaeological work at Failaka Island showed the need for geological study. Analysis of sediments related to drinking water-collecting cisterns was performed on a Late Islamic settlement (NE part of the island) in 2018. Field sedimentological, grain size and XRD analysis of the sediment profiles showed that the shallow (about 1 m deep) cone-shaped wells are dug in the loose, porous, cross-stratified calcareous coarse-grained quartz sandstones. Three upper layers of quartz sandstones in the profile have high infiltration rate and provide a rare yet ideal material for water retention. The fourth dense layer below, composed of very fine sand and silt fraction, tends to hinder water movement and forms a relatively impermeable water-resistant surface. Thus, the distribution patterns of clay content, grain sizes and porosity of the well-hosting sediments are favourable for freshwater infiltration and harvesting. An additional petrographic analysis was conducted on different types of rocks discovered on the archaeological site, used as building material and fragments of stone artifacts to identify their origin. It was established that archaeological building material is of local origin, whereas the source rocks for stone artifacts were imported.     

RAMESSIDE GLASS-COLOURING CRUCIBLES*

The preparation of glass in New Kingdom Egypt heavily involved the use of crucibles. Shape, mode of operation and function of these vessels have been reconstructed on the basis of new, stratified material from the excavation at Qantir, eastern Nile Delta. The crucible fabric, the internal layer protecting the vessel from the charge, and the glass melted in the crucibles are characterized by chemical and petrographic studies. The crucibles were apparently employed mainly to add the colourants to the glass. The broader archaeological context strongly suggests that glass production in the Late Bronze Age has been a highly developed, specialized and organized craft, with different factories for glass production, for colouring, and for working, connected by a wide-ranging trade network.     

Vagabond Capitalism and the Necessity of Social Reproduction

A vagabond, as is well known, moves from place to place without a fixed home. However, vagabondage insinuates a little dissolution—an unsettled, irresponsible, and disreputable life, which indeed can be said of the globalization of capitalist production. This paper reframes the discussion on globalization through a materialist focus on social reproduction. By looking at the material social practices through which people reproduce themselves on a daily and generational basis and through which the social relations and material bases of capitalism are renewed—and the havoc wreaked on them by a putatively placeless capitalism—we can better expose both the costs of globalization and the connections between vastly different sites of production. Focusing on social reproduction allows us to address questions of the making, maintenance, and exploitation of a fluidly differentiated labor force, the productions (and destructions) of nature, and the means to create alternative geographies of opposition to globalized capitalism. I will draw on examples from the “First” and “Third Worlds” to argue that any politics that effectively counters capitalism's global imperative must confront the shifts in social reproduction that have accompanied and enabled it. Looking at the political‐economic, political‐ecological, and cultural aspects of social reproduction, I argue that there has been a rescaling of childhood and suggest a practical response that focuses on specific geographies of social reproduction. Reconnecting these geographies with those of production, both translocally and across geographic scale, begins to redress the losses suffered in the realm of social reproduction as a result of globalized capitalist production. The paper develops the notion of “topography” as a means of examining the intersecting effects and material consequences of globalized capitalist production. “Topography” offers a political logic that both recognizes the materiality of cultural and social difference and can help mobilize transnational and internationalist solidarities to counter the imperatives of globalization.     

Novel use of cathodoluminescence to identify differences in source rocks for Late Paleoindian quartzite tools

Heterogeneous quartzite artefact finds from North America's Late Paleoindian period occur in several areas throughout the Northern Great Lakes region. Standard petrographic analysis, back-scatter scanning electron microscopy and cathodoluminescence are used to identify the properties of a regionally abundant, high-quality orthoquartzite stone as compared with high-quality Hixton silicified sandstone from the Silver Mound Archeological District in Jackson, Wisconsin. The results demonstrate the potential for reducing misidentification among material sources, and also exhibit the acutely discerning tendencies of pre-contact peoples. Lithological interpretations of thin sections identify the different properties of the Hixton material. Conversely, Mesnard quartzite, while it functions adequately as a tool stone, is fundamentally compromised of a tightly packed microstructure. This microstructure produces a hard, less tractable material with erratic breakage, possibly explaining Mesnard quartzite's limited distribution prehistorically.     

Chemical and Petrographic Analysis of Pre‐Hispanic Pottery from the Southern Abaucán Valley,Catamarca, Argentina

Neutron activation (NAA) and petrographic analyses were carried out on Late and Inca Period pottery from 15 archaeological sites and several clay samples in the southern Abaucán Valley, Catamarca, Argentina. The results from the NAA and petrographic analyses provide new data concerning local versus non‐local pottery production and vessel exchange for these two pre‐Hispanic cultural periods. The chemical data demonstrate the use of different clay sources over time until the Inca appearance in the region, when a more structured and controlled production is observed. Petrographic analyses show a similar change in the ceramic paste recipes used by ancient potters.     

The chert from the Castelltallat Formation (south-central Pyrenees): archaeometric characterisation and archaeological implications

Chert from the limestones and marly limestones of Castelltallat Formation (Ebro Basin) was widely used throughout prehistoric times in north-eastern Iberia to produce stone tools due to its properties and accessibility. A rough estimate indicates that this rock—either as raw material or as lithic products—was distributed mainly to the north of the outcrops, over an area of 6000–8000 km². However, other rocks in the area have similar characteristics which can lead to confusion in the interpretation of its prehistoric use and distribution. In order to establish useful archaeometric criteria for differentiating this chert from other similar, the Castelltallat chert is characterised in petrographic, mineralogical and geochemical terms. The chert nodules are found to be homogenous at the macroscopic and microscopic level, with a significant presence of bioclasts, thus indicating they might be formed in a freshwater lake environment by the early diagenetic replacement of carbonates in shallow waters. The mineralogical composition is homogeneously uniform and of a flint type, characterised by an almost exclusive predominance of quartz, without any opaline phases, and a variable proportion of moganite. The iron oxide content is very low, whereas its chemical composition is unusually high in uranium which correlates positively with carbonate content and negatively with silica. Archaeometrical parameters are provided to reach a proper identification of tools knapped with this chert. This way, chert from Castelltallat Formation turns out to be a valuable lithological marker to evaluate the range of mobility of the human groups who lived in the north-eastern Iberia and their contacts with neighbouring areas.     

Salt mining tools and techniques from Duzdaği (Nakhchivan,Azerbaijan) in the 5th to 3rd millennium B.C.

The emergence of mining reflects profound changes in the organization of late prehistoric societies. In terms of lithic and ore mining, salt is a highly strategic mineral resource which was exploited for its dietary and healing properties. The exceptional prehistoric salt mine of Duzda?i (Nakhchivan, Azerbaijan) is located in a high salt-bearing region centered on the Aras River in the Lesser Caucasus. Field survey, spatial recording of archaeological materials and use-wear analysis of macrolithic tools have allowed us to outline the mining operations and techniques there from the Chalcolithic period onwards. We have identified workshops for the manufacture and repair of tools, as well as salt extraction and processing areas.     

The Faragola Ceramic Collection: Ceramic Production,Consumption and Exchange in Seventh‐Century Apulia

A collection of 30 ceramic samples, 16 of coarse wares and 14 of fine painted wares, have been investigated by optical microscopy, scanning electron microscopy, inductively coupled plasma optical emission spectrometry, inductively coupled plasma mass spectrometry and neutron activation analysis. Further samples of clayey sediments, both locally outcropping and found within the settling tank, have been submitted to the same analytical techniques for comparison with the ceramic collection. The results demonstrated that local clayey sediments were used as received for the production of coarse wares. The same raw materials were sieved and/or refined by decantation for the production of fine painted wares, which, in fact, provided results that were perfectly comparable with those for the clayey raw materials found within the settling tank. The Faragola productions were distinguished from the neighbouring Apulian productions according to petrographic features (the presence of leucite‐bearing volcanic rocks and Mn‐rich wads) and their bulk chemical composition.     

2005 Cultural Heritage Legal Summary

Abstract

Archaeologists studying ancient state societies often divide political economic models into separate prestige goods and subsistence goods systems. For the Maya during the Late Classic period (ca. A.D. 600–900), scholars have suggested that the elite centrally controlled the production and circulation of prestige goods while local communities and households were responsible for subsistence goods manufacture and exchange, which operated in a largely decentralized fashion. We examine an alternative to this dichotomous system through a festival market model that postulates a wide array of social groups engaged in material goods exchange during ceremonial events and public festive gatherings. This model is investigated using modal, petrographic, and Instrumental Neutron Activation analyses (INAA) of Late Classic ceramic figurines from the Motul de San José region, Petén, Guatemala. Ceramic figurines are frequently associated with household affairs because of their presence in household middens. We find that paste types crosscut different household status groups and communities within the region and argue that figurines were exchanged within the context of festival markets. This exchange pattern has important implications for linking households to larger political and regional spheres of social and economic life.     

PETROGRAPHIC AND GEOCHEMICAL EVIDENCE FOR LONG‐STANDING SUPPLY OF RAW MATERIALS IN NEOLITHIC POTTERY (MENDANDIA SITE,SPAIN)

Pottery from the Neolithic Mendandia site has been studied. The radiocarbon dating of the site corresponds to a range of dates from 7488–7546 cal bc to 5283–5437 cal bc : the first occurrence of pottery is dated at 5968–6040 cal bc for the lower level III, and up to 5386–5560 cal bc for level II. The antiquity of the potsherds places them within the oldest pottery production sequences in the Iberian Peninsula, which adds to the interest of this study. Ten potsherds from level II and five from level III are analysed for their petrographic and chemical characterization. The petrographic data show two different methods of raw materials manufacture—intentionally tempered pottery (ITP), using calcite and/or limestone and grog, and naturally or non‐intentionally tempered pottery (NTP). According to the matrix paste features, on the basis of the amount, shape, and average or size range of the mineral inclusions, clayed (type A) and sandy (type B) paste types were established and related to two different source areas. The chemical features also indicate two raw material sources and are in agreement with the petrographic paste types. The absence of significant chemical and mineralogical differences between the pottery from levels II and III suggests two contrasting areas for raw materials supply that lasted for at least 600 years.     

THE JUDICIOUS SELECTION AND PRESERVATION OF TUFF AND TRAVERTINE BUILDING STONE IN ANCIENT ROME*

The Republican and early Imperial monuments of Rome are, for the most part, built of tuffs quarried from at least seven pyroclastic deposits erupted from nearby Monti Sabatini and Alban Hills volcanoes. Remarks by Vitruvius (2.7.1–5), field observations of the monuments, and petrographic and rock testing studies of samples from Roman quarries demonstrate that Roman builders developed a good knowledge of the diverse material properties of the tuffs over centuries of use and exposure. Measurements of compressive strength, specific gravity, water absorption and adsorption of water vapour confirm that the petrographic characteristics of each tuff lithology strongly influence its strength and durability. Early construction utilized weakly durable, soft or vitric tuffs such as Tufo del Palatino or Tufo Giallo della Via Tiberina that are susceptible to decay, as at Temple C (290 bc ) of the Largo Argentina Sacred Area. Late Republican structures, such as the Temple of Portunus (80–90 bc ), employed somewhat durable, vitric–lithic Tufo Lionato reinforced with travertine, a durable limestone quarried near Tivoli. Roman builders selected the material properties of the tuffs to advantage for specific structural elements within large public monuments of the first century bc and the first century ad , as at the tabernae of the Forum of Caesar (46 bc ), where an upper storey of lightweight Tufo Lionato is supported by robust, lithic–crystal Lapis Gabinus pillars and flat arches reinforced with travertine. The tuffs are not very durable building stones; Romans preserved them with protective stucco, and travertine and marble cladding. Their high water intake, coupled with direct exposure to rain, daily fluctuations in relative humidity and urban weathering at present makes them especially vulnerable to decay.     

Petrographic and Geochemical Investigations on the Pottery Production from Arslantepe–Malatya (Eastern Anatolia) from the Fourth to the Second Millennium BCE: Technological Continuity,Innovation and Cultural Change

The petrographic and geochemical analyses of 130 Late Chalcolithic 3 (LC3, 3800 bce ) to Early Bronze Age IIIB (EBAIIIB, 2000 bce ) ceramics from Arslantepe and the Malatya Plain in the Eastern Anatolian Upper Euphrates have identified critical differences in raw material procurement and paste preparation, reflecting typological, chronological and cultural changes. Based on these differences, distinct modes of production that correspond to phases reflecting significant social, economic and political changes were recognized. In particular, the interruption of the centralization process and the establishment of mobile groups during EBAI (3000–2900 bce ) were accompanied by the exploitation of new sources.     

STUDYING TECHNOLOGICAL PRACTICES AT A LOCAL LEVEL: NEUTRON ACTIVATION AND PETROGRAPHIC ANALYSES OF EARLY CERAMIC PERIOD POTTERY IN CENTRAL CHILE*

We discuss neutron activation and petrographic analyses of domestic ceramics and some raw materials from five archaeological sites in the Valdivia de Paine locality, in Central Chile. During the time period studied, the area was occupied by small‐scale horticultural groups with disperse and sedentary or semi‐sedentary settlement patterns. The analyses indicate that diverse local raw material sources were used in pottery production, and shared by members of different co‐residential units and between different cultural groups. The data indicate as many similarities as differences among the technological practices of pottery‐producing groups who lived in spatial proximity. The results have implications for the understanding of pottery‐producing communities at a local level, as well as small‐scale groups in general.
