Abstract
The Büyük Menderes Graben (BMG) of western Turkey is bounded by E–W oriented normal faults and has been a depositional center for thick sedimentary layers since the Miocene. Four Mio-Pliocene depressions (from west to east, the Çine, Bozdoğan, Karacasu,and Denizli basins) having overall N–S trends are situated just south of the BMG. In this study, we focused on the structural characteristicsof the BMG using Bouguer gravity data covering the area between 37°N and 39°N and 26°30′E and 30°E and gravity data along 4 profilesto estimate the discontinuous basement relief of the BMG. Our main objectives were to investigate the geometry of the faults boundingthe BMG and surrounding faults, and to describe the extent of the cross-graben structures. Boundary analysis, analytical signals, andsecond derivative methods were applied to Bouguer gravity data in order to determine tectonic border lines. The 2D inversion of gravitydata together with the analysis of the power spectrum for each profile exposed an image of the subsurface. As a result of both methods,the thickness of the sedimentary cover was determined to be 1.44–2.3 km in the BMG. According to model geometry, the thickness ofthe sedimentary deposits decreases to the south of the graben.
