Abstract
Estimation of the geothermal gradient using the depth of the magnetic source base is widely used in diverse geological environments. However, the determination of the base of the magnetic source does not necessarily represent the Curie Temperature depth, especially in complex geological provinces, as is the case of Mexico. Geothermal gradient has been determined in numerous sites that can be compared with the aeromagnetic data processing results and the occurrence of large differences has been documented. In this work, we present the coincidences and inconsistencies of the method and the parameters that affect the geothermal gradient estimation.
