2 Tectonosedimentary Evolution of the Eşen Basin 2.1 Introduction Geological Setting of Sw Turkey

The Eşen Basin is a ca. 30 km long and 15 km wide, NNE-SSW trending young graben which is located in SW Turkey between the Isparta Angle and the Western Anatolian Extensional Province (Fig. 3). The basin has a key position in the south-western part of the Fethiye-Burdur Fault Zone (FBFZ), which is a presumed strike-slip zone with faults that run through numerous small cities and villages. There is a critical need to advance our knowledge and understanding of the history of this complex fault system for two main reasons: 1) A spatial and temporal (4D) basin reconstruction would help to understand the role of the various fault systems, not only on a basin scale, but also within the larger FBFZ. 2) This kind of information is necessary for seismic hazard assessment of the Eşen Basin and its surroundings, which are moderately well studied in this context.
