Comparing of the 2D–3D Gravity Calculations in Cartesian Coordinates and 3D in Cartesian-spherical Coordinates

In this study, various calculations comparisons were made to achieve the best results in gravity computation. In the first study, 2D and 3D gravity computation were compared by using a suitable synthetic model in cartesian coordinates. And also in the second study, 3D gravity calculations are compared by using a suitable synthetic model in spherical and cartesian coordinates. In the first study, accuracy of the 3D gravity calculation results were found by inversion in cartesian coordinates. And also in the second study, the 3D gravity calculation results were found to be true in the spherical coordinates instead of in cartesian coordinates. The two studies, forward and inversion solutions were made for these model geometries by intensity of adoption by using a special algorithm (Çavşak H. 1992). Thus, the three-dimensional gravity studies are necessary to do is tried to explain in spherical coordinates.
