Petrographic and geochemical analysis on the provenance of the Middle Bronze and Late Bronze/Early Iron Age ceramics from Didi Gora and Udabno I, Eastern Georgia

We report thin section petrographic and geochemical analysis of a total of 20 Middle Bronze, Late Bronze/Early Iron Age ceramics excavated from Didi Gora and Udabno I located in the Eastern part of the Republic of Georgia and 31 clay samples from eight different regions in the surrounding areas of the sites. The major and trace element compositions of the ceramics and clays were determined using a wavelength dispersive X-ray fluorescence technique. The results indicate that the ceramics were manufactured from local clays in Eastern Georgia, mainly from two local clays without any preference of one of the sources during the Middle Bronze, Late Bronze/Early Iron Age.

2003年,对西安市楼阁台遗址进行钻探,发现东西并列的两个小城,及城内的主要道路和部分建筑遗址,并在西小城南墙北侧进行试掘,出土遗物大部分为建筑材料。西小城南墙可能始建于十六国时期,沿用至北朝时期。东、西小城应是自前赵以来,经前后秦、北朝直至隋初长安城的东西宫城遗址。     

Characterization of Iron age pottery from eastern Turkey by laser- induced breakdown spectroscopy (LIBS)

Selected pottery sherds coming from the Ayanis, Dilkaya and Karagündüz excavations in eastern Turkey and dated from the Early to Middle Iron Age were examined as regards their composition by using laser-induced breakdown spectroscopy (LIBS). The objective of the study was first to investigate the potential of the LIBS technique in the compositional analysis of pottery and further to explore correlations in spectral data, by using chemometrics methods that would possibly enable discrimination among different sherds. This work is part of a broader study aiming to examine clay variability both before and during the Urartian State period and to explore possible relationships and differences among pottery objects from fortresses and settlements or settlements and cemeteries on the basis of the clay composition of sherds. Preliminary results demonstrate that by using the LIBS technique it is possible to analyse pottery sherds in qualitative and semi-quantitative ways, providing information on the clay and slip composition. Furthermore, encouraging results have been obtained by carrying out principal component analysis (PCA) on the LIBS spectra, which suggest that in certain cases, it is possible to directly correlate spectral information with the origin of pottery sherds.     

An archaeometric study of the Konya basin metallic ware through FTIR and XRD analysis with chemometrics: Central Anatolian Early Bronze Age ceramics

Fourier-transform infrared, X-ray diffraction and chemometrics were used to characterize the mineralogical composition and firing conditions of 59 Early Bronze Age ceramic sherds from the Konya Plain (Turkey). These include the Konya Basin Metallic Ware (KBMW) and a control group of contemporary local products. The analysis indicates significant differences in mineral inclusions and firing temperatures, with KBMW generally being fired above 800°C and characterized by standardized fabric recipes. Assessed together with other published evidence, these results indicate a high degree of specialization in the production of KBMW ceramic assemblages in central Anatolia during the third millennium BCE.     

Geochemical and Petrographic Analysis of Late Bronze Age Cypriot Ceramics (White Slip I and II and Monochrome) from Tell Atchana/Alalakh (Hatay) in the Amuq Valley

White Slip ware, both White Slip I and II, and Monochrome ware are Middle to Late Bronze Age Cypriot pottery types found across a large area of the Eastern Mediterranean region. A vast quantity of these wares has also been uncovered in Tell Atchana/ancient Alalakh in Hatay in southern Anatolia. We analysed a total of 56 White Slip (n = 36) and Monochrome potsherds (n = 20) from Tell Atchana using XRF, ICP–MS and petrographic thin‐section methods. The main aim of the study was to explore the compositional characteristics of the wares and to determine whether they are local imitations of the Cypriot White Slip and Monochrome wares or represent Cypriot exports to this region. The analytical results proved that White Slip I and II were produced from raw clay of mafic and ultramafic source rocks exposed in the Troodos Massif, available in the Limassol area of southern Cyprus and traded to Tell Atchana. Examples of Monochrome ware excavated in Tell Atchana were also imported to the region, most probably from east/north‐east Cyprus. These results demonstrate a close trading connection between Tell Atchana/Alalakh and southern Cyprus during the Middle to Late Bronze Age.     

Alienated and politicized? Young planners’ confrontation with entrepreneurial and authoritarian state intervention in urban development in Turkey

Planning in Turkey is dominated by powerful market interests and authoritarian state regulation, resulting in a conflictual socio-political environment. Caught in the crossfire between interventionist urban policies and a planning education system that is oriented towards the public good, planners have come to feel alienated from their work. This paper considers how young planners respond to these challenges, drawing upon questionnaires and semi-structured in-depth interviews with planners with fewer than 10 years of experience. Their confrontation with entrepreneurial and authoritarian state interventions in urban development alienates them from their ideals, leading them to explore new ways of dealing with increasing political authority and economic neoliberalism. The participants of the study came up with a number of diverse responses related to this process. Disappointed with the practice of their profession ‘lost planners' begin searching for alternative pathways outside their practice towards a more meaningful society. In contrast, ‘profiteer planners' focus on getting more business and play a conformist and opportunistic role in the existing planning practice; while ‘struggling planners' develop alternative ways to pursue the public good by participating in urban movements. In short, they cope with alienation through politicization, solidarity and the identification of new means of engaging with society.     

Sequential Incisions on a Cave Bear Bone from the Middle Paleolithic of Pešturina Cave,Serbia

We present the detailed analysis of a cervical vertebra from a cave bear, found at Pe?turina cave, Serbia, in a Mousterian archaeological level dated by radiocarbon at 43.5–44.6 kyr cal BP, and by ESR to between 93.5 and 102.5 kyr BP. Identified as a portion of the cranial articular facet, the fragment displays ten subparallel grooves. The microscopic study of these grooves and other surface modification present on the bone fragment, conducted with multifocus optical and confocal microscopes and complemented by a taphonomic analysis of the associated faunal assemblage, supports the hypothesis that the incisions were made by humans. Results are used to critically examine ambiguities implicit in the analysis and interpretation of early engravings, a category of material culture that has been playing a key role in the identification of early instances of symbolically mediated behavior.     

Application of electron microprobe analysis to identify the origin of ancient pottery production from the Castillo de Huarmey,Peru

A vast amount of ceramics (among other grave goods) were recovered from Castillo de Huarmey, a Wari culture (650–1050 ce ) archaeological site on the north coast of Peru. In order to assess ceramic production area(s) and possible trade, political or cultural interactions with other regions, and to complement earlier petrographic analysis, electron microprobe analysis (EMPA) was conducted following a rarely used methodology in archaeology. The chemical composition of individual minerals in ceramics and sediments samples from the Huarmey Valley was obtained, focusing mainly on amphiboles, feldspars and pyroxenes. The results of the analyses clearly indicate that the majority of the ceramic analysed was made of raw material of local origin.     

Reflections on the Transformation in Mexico

This article offers panoramic portrait of Mexican politics since the election victory of Andrés Manuel López Obrador’s Morena movement in July 2018. Along its path to overwhelming success, Morena presented a vision of a historic transformation of a thoroughly corrupted Mexican state. Morena’s opponents viewed its emergence with anxiety, as a radical, populist, leftist force. But the new regime has been extremely cautious, affirming existing geopolitical and security commitments and pursuing conservative macroeconomic policies. Working within these constraints, the López Obrador government has largely focused on a moral transformation of the state. The context of Morena’s victory was the ongoing collapse in the Mexican state’s monopoly of force and its historic complicity with criminal and paramilitary violence. The government’s post-election approach has included a public reckoning with state crimes, from 1968 to Ayotzinapa. But its primary strategy has been one of ostentatious political asceticism. Rhetorically, this encompasses ideas of ‘political love’ and ‘republican austerity’; in practical terms, it includes campaigns of public frugality and the performative vulnerability of the president himself. In closing, we analyse the proposed National Guard, arguably the centrepiece of Morena’s putative state transformation, a policy condemned by some as renewed militarisation in the name of utopian republicanism.
