    The Effect of Case Hardening on the Natural Preservation of Stone Monuments, Fraktin Monument, Türkiye
    (Springer Heidelberg, 2025) Korkanc, Mustafa; Ince, Ismail; Huseyinca, Mehmet Yavuz; Tosunlar, Mehmet Bahadir; Hatir, Mehmet Ergun
    Case-hardening processes that develop in monuments reduce the porosity of rocks while increasing surface hardness. This situation may contribute to the transfer of cultural stone heritage markers to future generations by limiting the penetration into the rock structure of water, which is the most destructive agent in atmospheric weathering processes. This study focused on the Fraktin relief monument, which was created by the Hittites in the 13th century BCE by carving into the rock surface. The site was investigated to reveal the case-hardening mechanism and its effects on the physical properties of the rock. The geochemical formation mechanism of the surface-hardening process, which contributed to the survival of the Fraktin relief monument, was examined by use of scanning electron microscope-energy dispersive spectrometry (SEM-EDS) and analysis by an inductively coupled plasma-mass spectrometer (ICP-MS). In addition, the effect of the hardening on the physical properties of the rock was investigated with nondestructive tests applied both in situ and in a laboratory. The SEM-EDS and ICP-MS analyses revealed that amorphous silica filled the pores of the rock and created surface hardening. This situation has increased the geotechnical properties of the unit in which the monument was carved, making it more resistant to atmospheric processes.

    Assessment of Accumulation, Spatial Distribution and Sources of Potentially Toxic Elements (PTEs) in Sediments of a Saline Lake
    (Taylor & Francis Inc, 2025) Huseyinca, Mehmet Yavuz; Kupeli, Suayip
    Potentially Toxic Elements (PTEs) are hazardous for human and ecosystem health due to their non-biodegradable nature. In this study we investigated the concentrations of PTEs, including As, Co, Cr, Cu, Mn, Mo, Ni, Pb and V in sediments of Lake Tuz around the salt pans for possible contamination. Lake Tuz is a shallow saline lake where halite (table salt) production is carried out in the salt pans and has significant geo and eco-tourism potential due to its unique ecosystem and natural beauty. The extent of pollution level and ecological risk were evaluated by geochemical indices and guideline values. According to the Geoaccumulation Index (Igeo), Enrichment Factor (EF) and Contamination Factor (Cf) indices Cr, Mo, As and occasionally Ni accumulated in moderate to strong levels. Intensity maps of Pollution Load Index (PLI) and Modified Degree of Contamination (mCdeg) indicated pollution hotspots in the neck region and in the eastern shore of the lake respectively. The Potential Ecological Risk Index (PERI) values indicated low and moderate levels of ecological risk. Statistical analyses including Pearson Correlation Coefficient (PCC), Hierarchical Cluster Analysis (HCA) and Principal Component Analysis (PCA) suggested that Co, Cr, Cu, Mn, Mo, Ni and V are of geogenic origin and As and Pb are of anthropogenic origin. Provenance analysis suggested that host rocks for geogenic PTEs were granodiorites and ophiolites situated in the catchment area of the lake. Anthropogenic PTEs were most likely related to agrochemicals used in surrounding farmlands.

    Interpreting Sulfated Crusts on Natural Building Stones Using Sulfur Contour Maps and Infrared Thermography
    (SPRINGER, 2019) Korkanç, Mustafa; Hüseyinca, Mehmet Yavuz; Hatır, Mehmet Ergün; Tosunlar, Mehmet Bahadır; Bozdağ, Ali; Özen, Latif; İnce, İsmail
    In this study, the effect of sulfation due to air pollution in the portals of the Ince Minareli Madrasa built of pyroclastic rocks and the Karatay Madrasas (Konya, Turkey) built of marble was investigated. Since the sulfur element in sulfate salts is represented as sulfate, the sulfur contour maps (SCM), obtained by transferring the portable X-ray fluorescence measurements onto the orthophotographs, also show the sulfated crust formation, distribution and anomaly regions on the portal surfaces. Additionally, the anomaly regions originating from the difference in thermal conduction between the sulfated crusts and portal surfaces on thermal camera images were determined, and they were observed to be compatible with the anomaly regions on SCM. However, the size of this correlation depends on the chemistry of the building stone and the thickness of the sulfated crusts. Then, it was determined that the anomaly regions on SCM were distributed in relation to the washing out of sulfated crusts by rainfall and capillary moisture content. Accordingly, portal surfaces were divided into three as the sheltered, washing and capillary regions. Consequently, it was demonstrated that the sulfation effect due to air pollution on historical building surfaces which have appropriate rock chemistry can be determined by non-destructive testing methods like using the SCM supported by infrared thermography. The fact that the method is simple and repeatable and is easily applicable to other buildings was considered as the most important success of the method.

    Mineralogy and Geochemistry of Sediments From Lake Tuz
    (2021) Hüseyinca, Mehmet Yavuz; Küpeli, Şuayip
    Lake Tuz is in a closed basin, in the center of the Anatolia (Turkey). The lake has shallow hypersaline water. In this study, mineralogical and geochemical features of the lake sediments sampled by core drillings were investigated. Halite, polyhalite, calcite, magnesite, dolomite, huntite, quartz, and albite minerals were found in bulk sample and montmorillonite and vermiculite minerals were found in the clay fraction XRD analyzes. In geostatistical evaluations, elements are divided into four clusters. These clusters are named as Clastic, Hydrothermal, Evaporite-carbonate and Evaporite-sulphate. Trace elements included in the clastic cluster were used to interpret provenance. The Light Rare Earth Element (LREE) enriched chondrite normalized average REE pattern suggests a cratonic provenance for the lake sediments except for the low negative Eu anomaly. Trace element ratios of La/Sc, La/Co, Th/Sc, Th/Co, Zr/Sc, Zr/Co, Ba/Sc, and Ba/Co, which are critical for provenance, show a provenance in a “felsic-intermediate magmatic” composition. According to the La-Th-Sc diagram, the tectonic setting of the source area was found as "Continental Island Arc".

    Geochemistry of Upper Eocene-Oligocene sandstones from Tuzgölü Basin (Central Anatolia)
    (2022) Hüseyinca, Mehmet Yavuz; Küpeli, Şuayip
    In this study, mineralogical and geochemical features of Upper Eocene-Oligocene sandstones exposed by the Tuzgölü Fault Zone (TFZ) at the eastern border of the Tuzgölü Basin were investigated. The absence of zircon enrichment in the Zr/Sc-Th/Sc diagram indicated no sedimentary recycling. This shows that the sandstones are first cycle sediments, that is, the material transported directly from the source. Critical element ratios for provenance such as La/Sc, La/Co, Th/Sc, Th/Co, Th/Cr, Zr/Sc, Zr/Co, Ba/Sc, and Ba/Co, Th/Sc-Eu/Eu* diagram and average Rare Earth Element (REE) pattern suggest a provenance in “intermediate magmatic” composition. The variation in the negative Ce anomaly effect observed between the lower and upper parts of the sequence indicates variation in the oxygen level of the water. In each of the La-Th-Sc, Th-Co-Zr/10, and Th-Sc-Zr/10 tectonic setting discrimination diagrams, the sandstone average fell onto the “Continental Island Arc” position. This tectonic setting defines the arc that developed along the continental margin of the subduction zone. The tectonic setting found for the basin, supported the evolution model that the Tuzgölü Basin developed as a fore-arc basin.
