Abstract: Mineral exploration is the underlying theme of industry and discoveries because humans havebeen exploring for minerals from the very beginning, based on their needs. This research aims to find promisingareas of iron ore mineralization in Chak-Chak Exploration area of Yazd province, Iran. The study’s range lies ata latitude of 32-33 degrees north and a longitude of 54-55 degrees east. This study collected data using terrestrialmagnetometry at 6222 points in a 20 m x 10 m grid. Initially, these data were pre-processed, such as removing themagnetic field effect of the Earth’s core. Subsequently, processes such as applying polarisation filters, trend surfacecorrection, upward and downward conversions, vertical derivatives and analytical signals on the terrestrial magneticdata were performed. The Exploration range contains numerous peaks in the southwest and other summits in thenortheast, according to the research findings. These anomalies are consistent with igneous rock units (rhyolites) andfaults. Consequently, it may be stated that one of the most rapid and least costly methods of detecting iron anomaliesis terrestrial magnetism, which produces satisfactory results.
