In this study, the Parker Oldenburg method, also known as Parker's generalized method, is utilized to ascertain the depth of the basement. This specific approach has been extensively employed in numerous studies to determine the depth of the Moho boundary, which in turn aids in the identification of tectonic activities, occurrences of earthquakes, and various other phenomena. In order to obtain a comprehensive understanding of this method, Ultimately, the method is applied to actual data from a region located in the central desert of Iran. This endeavor allows us to construct a model and subsequently determine the depth of the basement within this specific region, while concurrently analyzing the data.Also, rms error and geological evidence will confirm the results.
