Article Citation - WoS: 1Citation - Scopus: 1Calcite Precipitation on Excavated Andesite Surfaces From the Archaeological Sites of Aigai and Assos (turkey)(Springer Heidelberg, 2024) Kaplan, Caglayan Deniz; Boke, HasanThe conservation interventions of crusts or patinas formed on the surfaces of stone monuments should be evaluated within a comprehensive approach in archaeological excavations, taking into account their material characteristics. In this study, the mineralogical, chemical and microstructural characteristics of whitish crusts formed on the surfaces of buried and later excavated andesite surfaces at the archaeological sites of Aigai and Assos (Turkey) were investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), X-ray fluorescence (XRF) and scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS) analyses in order to establish a conservation approach at the archaeological sites. The whitish crusts formed on the excavated andesite surfaces are mainly composed of calcite with freshwater diatom species. Calcite is most likely formed by the alteration of plagioclase by carbon dioxide in the soil during the burial of the andesites. In the soil, CO2 reacts with plagioclase to produce kaolinite and calcite which are precipitated on the andesite surfaces after excavation. The presence of freshwater diatom species in the whitish crusts may indicate that the andesite remains were buried in the waterlogged soil for many years and later excavated. Therefore, whitish crusts should not be cleaned from the andesite surfaces, as they are a sign of the burial history of the monuments and a protective layer against weathering.Article Evolution of a Medieval Castle Town and Its Landscape in the Southwestern Anatolia(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2023) Etlacakuş, Aysen; Turan, Mine HamamciogluThe objective of this paper is to develop a framework for understanding the archaeological sites composed of the remains and traces of castle towns and evaluating these sites together with their landscapes with a retrospective focus. A case study approach was undertaken with a focus on Kale Tavas (Tabae) in the Southwestern Anatolia. The scope of the Historic Landscape Characterisation was adapted to characterise the remains and traces of the castle town together with its landscape. Site survey at different scales, archive research, and in-depth interviews were used to acquire data. Our results suggest the related conservation boundaries should be determined not only considering the citadel walls but also the natural context that had contributed to the evolution of the castle town. For Kale Tavas, heritage management should be planned by considering the values of the historical landscape and the factors that threaten them, as this study shows.Article Citation - WoS: 1Citation - Scopus: 1Profiling the Bacterial Diversity in Historic Limestone From Anazarbos Archaeological Site by Advanced Molecular and Spectroscopic Techniques(University of the Aegean, 2022) Aydın, Rozelin; İpekci, Emre; Daday, Mine Taykurt; Yüceer, Hülya; Böke, HasanThe architectural remains as well as sculptures, mosaics, and other artifacts in the archaeological sites are mostly made of stone and susceptible to biodeterioration by microorganisms. Bacterial communities are known to have the most effective role in biological deterioration in stones. The ancient city of Anazarbos (Anavarza), chosen as the study area, is the 1st Degree Archaeological Site in the vicinity of Dilekkaya Village, Kozan District, about 70 km north of Adana. The microbiological, chemical, mineralogical, and microstructural properties of stone samples taken from different places were studied in this research. Samples were taken from i) where no deterioration occurred, ii) where different forms of deterioration were observed, iii) archaeological deposits, iii) archaeological deposits that came from deteriorated stone samples area. Spectroscopic, thermal, and microscopic techniques applied included: X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy-Energy Dispersive System (SEM-EDS), Thermogravimetric Analysis/Differential Thermal Analysis (TG/DTA). The bacterial biodiversity was analyzed by the application of Illumina-based next-generation sequencing methods. Results show intense biological colonisations with clay minerals on limestone surfaces. A patina of clay minerals was observed on newly excavated stone surfaces, while biological colonisations have not yet intensified. The metabarcoding analysis showed 15 bacterial phyla. The Proteobacteria and Actinobacteria were the most abundant phyla in both stones and archaeological deposits samples. Human activity (intensive agriculture, animal husbandry), accumulation of rainwater in excavated areas adversely affects stones, which leads to acceleration of biological deterioration in stones. Thus, all features of the site require multi-faceted studies prior to unearthing of archaeological remains.Article Citation - WoS: 1Citation - Scopus: 1Anastelosis of Greco-Roman Temple Remains in Western Anatolia: Principlis, Implementations and Assessment(Taylor & Francis, 2020) Toköz, Özge Deniz; İpekoğlu, BaşakAnastelosis, which is defined as the reassembly of a structure by bringing together its existing original fragments, is a technique of conservation and presentation in archaeological sites. The aim of this study is to contribute to the conservation and presentation of the structures and to determine the basic principles to be considered during the implementation by analysing and evaluating the anastelosis implementation at temple structures in Western Anatolia, Turkey. The authors examined on-site evidence, archival and literature review. Analysis criteria were determined as emphasis of the structure within site scale and in original state, structural and visual integrity of the monument, authenticity, reliability, distinguishability, visual and material compatibility, reversibility and re-treatability. As a result, it was pointed out that the principles of reversibility/re-treatability and distinguishability should be managed while providing reliability, compatibility/structural and visual integrity in line with the preservation of authenticity.Article Citation - WoS: 6Citation - Scopus: 9Reconstruction of Archaeological Sites: Principles Practice and Evaluation(Taylor and Francis Ltd., 2012) Yaka Çetin, Funda; İpekoğlu, Başak; Laroche, DidierThe reconstruction works at archaeological sites need to be approached with caution to prevent disturbing any surviving evidence. This study aims to develop criteria for the evaluation of reconstructions at archaeological sites. The criteria have been developed through review of current international and national conservation charters to help improve reconstruction proposals. These criteria are determined considering the remain scale and the site scale. Accuracy of the reconstruction, avoidance of physical damage, compatibility of materials, distinguishability of the interventions, availability of the interventions for future applications, and reversibility are the criteria concerning the remain scale; limits of the intervention, retainability of the original characteristics of the site, and perception of the reconstruction are the criteria concerning the site scale. These criteria are applied to the reconstruction works realized at the West Stoa of Agora, zmir, Turkey during 1930s, which had to be dismissed and reimplemented in 2000s. The recent reconstruction was applied with compatible materials; the interventions did not damage the original materials and they are distinguishable. This study of the reconstruction presents the latest architectural information, provides a basis for future studies, and is reversible. The reconstructed structure does not falsify the original characteristics, but enables increased perception of the site.Article Citation - WoS: 10Citation - Scopus: 12Weathering of Andesite Monuments in Archaeological Sites(Elsevier Ltd., 2013) Kaplan, Çaglayan Deniz; Mürtezaoğlu, Fulya; İpekoğlu, Başak; Böke, HasanArchaeological sites, which are the integral parts of cultural heritage, have to be conserved as a whole to have a variety of information about past societies. In this study, the weathering problems of unburied and newly excavated andesite monuments in Aigai archaeological site (Manisa, Turkey) were investigated for the purpose of their conservation. With this intent, the basic physical properties, mineralogical and chemical compositions and microstructural properties of sound and weathered samples were determined by using XRD, SEM-EDS, FT-IR and TGA analysis. Results of the study indicated that the weathering mechanisms of unburied and post-excavated andesite differ from each other. The main weathering problems observed on the unburied stones are mainly increasing microcracks from inner parts to the surfaces, deposition of iron oxides and microbiological colonization due to climatic conditions of the site. In the newly excavated areas, calcium carbonate deposition, accumulation of clay minerals and microbiological colonization are the main weathering problems due to weathering of silica minerals through the action of carbon dioxide and water during burial.
