    Geophysical methods are frequently used in archaeological sites to obtain significant priori information. These methods assist archaeological excavation strategies by indicating the anomaly zones that may be associated with buried remains. Archaeo-geophysical methods are based on measuring the physical parameter contrast (e.g. magnetic susceptibility, dielectric constant, resistivity, density) between the buried archaeological remains and the covering environment. In this study, magnetic and ground penetrating radar methods were applied to contribute to excavation planning. The study area is a historical cemetery and has been used as an interment area for about 1000 years. Considering the information obtained from the previous excavations, the research depth was initially planned not to exceed 3 meters in general, but information up to 10 meters was obtained. We aimed at determining possible graves in the area outside the walls of Square Cemetery in Ahlat (Bitlis) district. After performing some data-processing steps to the raw data obtained, magnetic and ground penetrating radar anomaly maps were produced. Based on the distinguishable geophysical traces most promising locations were determined and suggested for archaeological excavations.

    Geophysical Investigation of Mount Nemrut Stratovolcano (Bitlis, Eastern Turkey) Through Aeromagnetic Anomaly Analyses
    (Springer Basel Ag, 2020) Ekinci, Yunus Levent; Buyuksarac, Aydin; Bektas, Ozcan; Ertekin, Can
    Quaternary Mount Nemrut stratovolcano, having a spectacular summit caldera and associated lakes, is located north of the Bitlis-Zagros suture zone, Eastern Turkey. Although much attention has been paid to its geology, morphology, history and biology, a detailed geophysical investigation has not been performed in this special region. Thus, we attempted to characterize the stratovolcano and the surroundings using total field aeromagnetic anomalies. Potential field data processing techniques helped us to interpret geologic sources causing magnetic signatures. Resulting image maps obtained from some linear transformations and a derivative-based technique revealed general compatibility between the aeromagnetic anomalies and the near-surface geology of the study area. Some high amplitude magnetic anomalies observed north of the Nemrut caldera rim are associated with the latest bimodal volcanic activity marked by lava fountains and comenditic-basaltic flows occurred along the rift zone. After minimizing the high-frequency effects, a pseudogravity-based three-dimensional inversion scheme revealed that the shallowest deep-seated sources are located about 3.0 km below the ground surface. Two-dimensional normalized full gradient solutions also exposed the depths of these anomaly sources, in good agreement with the inversion results. This first geophysical study performed through aeromagnetic anomalies clearly gave insights into some main magnetized structures of the Mount Nemrut stratovolcano.
