Abstract

Summary

Gravity method is a natural potential field method which is frequently used in geophysical investigations. The main principle of the method is to determine the buried structures in the ground by taking advantage of the changes in the vertical direction of gravity acceleration. There are many different methods developed to determine the depth of structures. In this study, the mean depth values of Bouguer gravity data obtained in Dikili district of İzmir province were determined using Radial Amplitude Power Spectrum Method (RAPSM) based on 2D Fourier transform. The greatest advantage of this method over the conventional power spectrum is that it works by determining the mean value of the cross-sections taken in different directions. Thus, it does not matter what direction the user takes the cross section and the depth of the structure can be determined more accurately. As a result of the application, the average depth values of the basement structure of the study area were determined. The topography of the basement structure varies between 320 m and 640 m in the region.
