Abstract

In exploratory geophysics, main and primary purposes are determination of researching targets densities, which have a particular density difference with that of the host rock. In this study, hence, we introduce new method for density determination, called "variogram method”, which is based on the fractal geometry. It is based on minimizing the Bouguer anomaly surface roughness in which fractal dimension of the surface is used as Bouguer anomaly surface roughness criterion. Through this method, we can determine the optimum density of charak in the South Hormozgan, which is utilized in order to accomplish some corrections and review their results about isostatic circumstances of those regions. There are various methods to illustrate the bedrock topography and we will explain one of these methods at the present paper. The calculation is dome in the Fournier domain. The method mentioned above was implemented to detect the bedrock topography and the results were compatible to the region geology.
