Two dimensional gravity modeling and inversion

Two Dimensional Gravity Modeling and Inversion. While scientific purposed gravity studies can successfully applied on lands and on seas now-a-days, usage and development of gravity method become important with the time. Parallel to improving technology, these studies become more economic and much fester. Gravity model studies of basic geometric figures have been done since the beginning of science of geophysics. In study, the gravity method are applied models that obtained from real data. In addition, combinations of the gravity value and its model geometry are used in inversion calculation and the most suitable formation densities that explain the gravity, are obtained. Underground model geometries and observed anomaly values of profiles that used in this study, are provided from one of the government agency. Vertical sections of below the formation profiles, which are obtained underground geometries, are identified as polygons. Using Talwani method, their 2- dimension gravity anomalies are calculated both using assumed densities, and then, using interpretive values of inversion method of these assumed densities. Software used in these calculations were written by Dr. Çavşak. In the models, both situations of excluding of boundary effect and including boundary effects are investigated. Moreover, similar density masses, that are identified in preliminary studies, are assumed as different density and using inversion method, their densities are recalculated. Later, these masses are added up and used in calculations in order to obtained more logical results. Key words: Gravity, Modeling, Inversion, Observed Anomaly, Calculated anomaly
