The continental interior of Mexico is characterized by a Late Cretaceous prominent fold-thrust belt that shows characteristics of an eastward-tapering orogenic wedge. According to structural data and geothermometry of the deformation, this wedge is the result of horizontal stresses directed from the west (Pacific domain). The orogenic wedge is bounded to the west by the Guerrero Terrane, which is the second largest juvenile terrane accreted to the North American Cordillera. The possible linkage between the accretion of the Guerrero Terrane and the regional shortening in the Mexican interior is examined in detail in the region comprised between the Sierra de Guanajuato and the Peña de Bernal—Tamazunchale areas. In order to test the accretion hypothesis, we present key stratigraphic, structural, and geochronologic data from the Mexican Cordillera in central Mexico, and discuss the problems that exist in connecting the accretion of the Guerrero Terrane to the orogenic deformation of the Mexican continental interior.

El campo geotérmico de Pathé está localizado en una secuencia volcánica del Mioceno Tardío al Plioceno en una región de fallamiento normal activo. Estas fallas se agrupan en dos tendencias de dirección aproximada NS y cercana a la EW. El grupo EW es la extensión meridional de la semifosa tectónica de Aljibes cuya falla maestra es curva con un desplazamiento vertical compuesto de 480 m. El desplazamiento somero es hasta de 70 m, y el fallamiento EW está generalmente localizado a lo largo de un área semielíptica de 34 km constituida por una meseta basáltica y conos cineríticos. El fallamiento NS define la fosa tectónica de San Francisco, con desplazamientos verticales de alrededor de 30 m, incrementándose hasta 180 m en el subsuelo. Estas rocas Neógenas están intrusionadas por numerosos diques de dirección EW y troncos de rumbo NS. Producción de vapor generalmente ocurre en la zona de intersección de la parte oriental de la fosa tectónica de San Francisco con el fallamiento EW. Fuentes hidrotermales activas están localizadas sobre una de las fallas de rumbo EW. Alteraciones hidrotermales a lo largo de segmentos de fallas y fracturas sugieren actividad hidrotermal antigua.
