Abstract

The first author, Cemal Kaya, passed away in February, 2022. The Turkish geophysical community will always remember Cemal Kaya’s friendship, honesty and sincerity. He graduated from Istanbul Technical University (ITU) Faculty of Mines, Department of Geophysical Engineering in 1981. He started his career as a geophysical engineer at the General Directorate of Mineral Research and Exploration. He completed his MS and PhD under my supervision at Ankara University. We completed many research projects in the 1990s, including the controlled-source audio-magnetotelluric (CSAMT) method for massive sulfide exploration and the magnetotelluric method in geothermal resource exploration, the first examples in Türkiye. We also initiated the systematic use of the MT method in crustal research as a joint TÜBITAK project of Ankara University and the General Directorate of Mineral Research and Exploration in 1995. This article is the first profile of national crustal research project. Since only two-dimensional modelling could be applied in the 1990s, a conductive artefact zone appeared under the Hisarlıdağ uplift in the resistivity model since the Thrace Basin surrounded by the Aegean, Marmara and Black Seas on three sides. Now, we have constructed a more realistic model of the Thrace Basin using the three-dimensional modelling that permits including the seabed topography.
