The purpose is to determine the total thickness of the sedimentary units and the basement topography, to clarify the underground structure, to identify the regions that can operate in terms of geothermal energy and the lateral discontinuities of the sedimentary units. The study was carried out in the eastern part of Sindirgi/Balikesir Province (Turkey). 60 MT and AMT measurements were made in the area and the deep geological structure was tried to be clarified. Paleozoic metamorphic rocks and the Upper Cretaceous age series which are incompatible with them were found in the study area. Upper Miocene volcanics unconformably overlie the complex sequence. These units cover alluviums unconformably, especially in stream beds. According to the results, it was found that there were many lateral discontinuities in which the throws and directions were very different from each other. When the cross-sections were examined in terms of the resistivity distributions, it was observed that low resistivities, high-very high resistivities dominated deep in the regions near the surface. The low resistivity zones between very high resistivity blocks were interpreted as a possible volcanic activity in the area.","PeriodicalId":134345,"journal":{"name":"10th Congress of the Balkan Geophysical Society","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132229437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The survey area has formerly been postulated as the location of a buried caldera that was one of the main eruptive centres of Cappadocian Volcanic Province. Three-dimensional non-linear conjugate gradient inversion of magnetotelluric data by using the full impedance tensor helps to delineate the subsurface resistivity distribution. The derived resistivity model reveals the possibility of a buried caldera. The low resistivity anomalies are interpreted as the clay alteration zones caused by hydrothermal activities.","PeriodicalId":134345,"journal":{"name":"10th Congress of the Balkan Geophysical Society","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128602099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present a successful case study, where local geophysical noise sources were overpassed by using ERT method. High-resolution 2D models allowed to locate buried remains of old facilities and even to reconstruct the footprint of an old building which displayed a complex “L” shape. The 3D ERT resulted model allowed to compare different sectors of the building, to extract the most probable foundation structure (different on two wings) and to analyze the construction rubble filling material.","PeriodicalId":134345,"journal":{"name":"10th Congress of the Balkan Geophysical Society","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122764098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
