Geophysical investigations of the Seferihisar geothermal area, Western Anatolia, Turkey

Evaluation of gravity data by using artificial neural networks case study: Seferihisar geothermal area (Western Turkey)

“…The geothermal activities of the region are controlled by fault tectonics. Agamemnon, Cumalı, Tuzla and Doğanbey are the main faults (Drahor and Berge, 2006;Magri et al, 2010). The Seferihisar area is consisted of Paleozoic metamorphic rocks of the Menderes Massif, Mesozoic Bornova Flysch or Melange, Cenozoic volcano-sedimentary rocks, and Quaternary alluvium deposits (Magri et al, 2010).…”

“…The focal depths are approximately 500 m for Tuzla fault and 450 m around the Karakoç hot spring. Drahor and Berge (2006) used magnetic, VLF, and self-potential data to characterize the structures of the geothermal system between the Cumalı and Doğanbey hot springs in the Seferihisar geothermal area. Bouguer anomaly map of the region is shown in Fig.…”

“…Many geological and geophysical studies have been carried out on this region. Self-potential (SP), magnetic, and very low frequency electromagnetic (EM-VLF) methods were applied in the area to identify fault zones and to describe the features of geothermal system (Drahor and Berge, 2006). Furthermore, resistivity and gravity studies were applied to characterize the area.…”

Assessment of geothermal energy potential by geophysical methods: Nevşehir Region, Central Anatolia

“…Turkey has four main geothermal energy regions; the West, Central and East Anatolian regions, and the North Anatolian Fault Zone where there is young volcanic activity (Drahor and Berge, 2006). Among these especially the west Anatolia region has the highest geothermal potential.…”

Interpretation of VLF Measurements Related to Hydrogeological Surveys

“…The advantages of the specific electromagnetic method are that (a) it is very quick in fieldwork, (b) light equipment is used and (c) the data collected are quit easy to be interpreted in a qualitative manner. It is a favourable tool for many professional geologists-geophysicists as well of many researchers who apply VLF methods in addition with other geophysical methods in order to study hydrogeological problems as well as geotechnical ones (Benson 1997, Sampaio and Dias 2001, Hautot et al 2002, Sharma and Baranwal 2005, Drahor and Berge 2006a, b, Zlotnicki et al 2006). …”
