| Abstract | The surface exploration of the Domos de San Pedro geothermal field located in Nayarit, Mexico indicates that the permeability of the reservoir is controlled by regional and local tectonic structures. The emplaced of the San Pedro dacitic domes is related along a NW-SE direction and this is limited mainly by the NE-SW normal faulting. The conductive structures of the fluid have a NW-SE and E-W trend, with possible suspicion the N-S normal faulting. These conditions are hosting the geothermal fluid of high enthalpy in the granitic-granodioritic complex of the Jalisco Block, associated with a propylitic alteration and confined by a clay cap which alters the andesites of the Miocene. |
