Abstract

To optimize the widespread use of fossil fuels in Iran, different resources of renewable energy can be considered as promising challenges. The everincreasing energy demands of the country can be satisfied by the very rich resources of renewable energy such as wind, solar, biomass, and geothermal energies. This paper presents the results of Curie Point Depth calculations from spectral analysis of Aeromagnetic Data for preliminary exploration of Geothermal Resources in central region of Kerman Province. The calculations were performed for an area of 22010 km2 located north of Jiroft city and east of Baft city. RTP correction and band pass filtering were first applied to the data. Then, the block dimension of 80×80 km with an overlap of 50% was selected for the spectral analysis. The spectral power was calculated for all the blocks and the Curie depth map was obtained for the study area. The results showed that the shallowest Curie depths are about 9 km observed in the southeastern part of the study area. Different information layers including geological and surface information layers were, then, onvestigated in the ArcMap software. Concentration of several hot springs and presence of faults, intrusive structures, and volcanic rocks prove a high probability of geothermal anomaly in the area of shallowest Curie depth.
