Three-dimensional models of the crustal electrical resistivity were derived from the inversion of magnetotelluric data in the eastern end of the Gediz basin, western Anatolia. In total, 179 MT sites measured in three different areas have been used in modeling. The study aims at providing information about the electrical resistivity distribution in the subsurface and its relations to structural setting and fluid pathways mainly controlling the development of geothermal reservoirs in the upper crust. The electrical resistivity models reveal a surficial low-medium resistivity layer associated with Neogene-Quaternary supradetachment sedimentary succession and a deeper high resistivity layer related to the Central Menderes Massif. The sedimentary cover over the metamorphic basement includes undulations, presenting an asymmetric extensional basin. The thickness of the sedimentary layer varies along strike from west to east and reaches approximately 3 km (max) in the graben. An anomalously conductive zone associated with a clay alteration zone was observed in this layer. The resistivity models also bring out two deep conductive zones along the southern margin of the basin: a conductive zone that could be interpreted as a geothermal reservoir at the easternmost end of the basin, however instead described as a part of a deep low resistivity zone with regional extent and another conductive zone interpreted as a region possessing an interconnected fracture network developed mainly by the extensional tectonic regime and that probably contains geothermal fluids. Moreover, normal faults exposing along the basin margins characterize the geometry of the basin, and particularly the main graben-bounding fault and Gediz detachment fault provide possible fluid pathways in the upper crust.

地壳电阻率的三维模型是根据安纳托利亚西部格迪兹盆地东端的大地电磁数据反演得出的。总共在三个不同区域中测量的179个MT站点已用于建模。该研究旨在提供有关地下电阻率分布及其与构造环境和流体路径的关系的信息，这些信息主要控制上地壳地热储层的发育。电阻率模型揭示了与新近纪-第四纪超分离沉积序列相关的表层中低电阻率层和与中央Menderes断层有关的更深的高电阻率层。变质基底上的沉积覆盖物包括起伏，呈现出不对称的伸展盆地。沉积层的厚度沿从西向东的走向变化，在grab岩中达到约3 km（最大）。在这一层中观察到与粘土蚀变带相关的异常导电带。电阻率模型还沿着盆地的南缘带出了两个深部的传导带：一个传导带，可以解释为盆地最东端的地热储层，但是却被描述为深部低电阻率带的一部分，区域范围和另一个导电带，其解释为一个具有相互连接的裂缝网络的区域，该裂缝网络主要由伸展构造带发展而成，并且可能包含地热流体。此外，沿盆地边缘露出的正常断层是盆地的几何特征，
