- Normal faulting in the Pathé geothermal area, Central Mexico Miguel Carrillo Martínez Ciencias de la Tierra structural geology Pathé geothermal field The Pathé geothermal area is located in Late Miocene to Pliocene volcanic rocks in a region of active normal faulting. Thesefaults cluster in sets striking near E-W and close to N-S. The east-west fault set is the southern extension of the Aljibes half-grabenwhose master fault is curved and has a composite vertical offset of 480 m.Near-surface vertical displacement is up to 70 m, while E-W faulting is generally located along a 34 km long semielliptic areaof plateau basalts and cinder cones. The N-S faulting defines the San Francisco graben, with vertical offsets of around 30 m,increasing up to 180 m below the surface. Neogene rocks are intruded by numerous roughly east-west trending dikes and northsouthtrending stocks. Steam production occurs at the intersection of the eastern San Francisco graben with east-west faulting. Hotspring activity is located on an E-W trending fault. Hydrothermal alterations along fault and fracture segments suggest earliergeothermal activity. 1998 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56837205 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.37
