Abstract :In this study, discontinuities and major tectonic boundaries are interpreted in and around Türkiye by Bouguer gravity anomaly. The World Gravity Map 2012 is used for the interpretation of major tectonic features in the Anatolia Region. Radial average power spectrum (RAPS) and band-pass filter are used for long and short wavelength separation. For the whole study area, four depth segments are detected. Moreover, the radial average depths of these depth segments are 54.9 km, 32.2 km, 21.9 km and 8.0 km. In order to conduct better interpretation, the study area was divided into three subareas from the west to the east (area 1 to area 3). In area 1 (41.4 km, 21.2 km and 7.8 km) and area 2 (48.1 km, 20.0 km and 6.6 km), three depth sources are detected. Furthermore, four various depth segments are analysed in area 3 (54.3 km, 29.8 km, 20.8 km and 8.6 km). The interpretation of the whole study area, area 1, area 2 and area 3 showed that depth of the sediment  accumulation in the Western Anatolia is estimated as 7.8 km.
