Abstract

© 2016 SEG.In this study, wavelet transform was used for identifying the locations and boundaries of discontinuities in gravity data. Therefore this method was applied both synthetic models and field data. One and two prism models were used to compare structural effects. In addition, the square root of the sum of the squares of the H, V and D components (HVDM) method and relief shaded maps of wavelet transform results were investigated for comparing the results. A Bouguer gravity data set from eastern part of Turkey is used for field data. The eastern part of Turkey which has major tectonic structures, with the effect of Arabian Plate's northward motion, Anatolian block and Northeastern Anatolian Block escape to west and east, respectively. The study area includes major tectonic elements such as East Anatolian Fault (EAF), Malatya Fault (MF) and Bitlis-Zagros Suture Zone (BZSZ). In synthetic part of our study, the locations and boundaries of one and two prism models were successfully determined with using wavelet transform especially in the results of vertical and horizontal components and also HVDM method. In field study, MF, one of the major tectonic elements in study area, was detected in the result of vertical component; EAF and BZSZ were detected in the result of horizontal component of wavelet transform. The location of same tectonic elements was also observed in the results of the HVDM method and relief shaded map.
