3D Modeling of Gravity Anomalies Using 2D Synthetic Models

Abstract

The advantages of 3D gravity studies have been investigated in this study. For this purpose, first of all, 3D four different synthetic models geometry have been designed in order to determine the importance of 3D gravity study. The studies have been done with the first mass model have been described in this study. Then, 3D gravity anomalies have been calculated by using a special algorithm, for this model geometry by intensity, the algorithm results have been used in the next 2D and 3D inversion algorithm as measurement value. The calculated densities by different inversion algorithm and the other calculated parameters, as shown in the following order, have been compared with each other: 1. The forward solution 2D models have been compared with the forward solution 3D simulation models. This test has been done in order to prove 2D and 3D simulation model geometries are same. 2. The forward solution 3D original model has been compared with the inverse solution 2D and 3D simulation models. Here, as expected, the 2D and 3D simulation model intensities are equal to each other, but 3D original
model intensity is different from the others. 3. The forward solution 3D original model has been compared with the inverse solution 3D original model. This final step has been done for the test. Thus, according to the manner of formation, in item 2 of the above mentioned, why 3D gravity study should be done instead of 2D gravity study have been worked to explain. Giving accurate results of gravity studies of the first condition, model geometries have been defined as 3D. As a result, the following can be said that 3D gravity studies should be done instead of 2D gravity studies
