“…In the northern Gulf there are several tectonically active and inactive rift basins (Persaud et al 2003;González-Escobar et al 2006;Aragón-Arreola and Martín-Barajas 2007;González-Escobar et al 2009;MarHernández et al 2012;Sojo-Amezquita 2012;Martín-Barajas et al 2013). The group of active basins in the northern Gulf includes Wagner, Consag, Upper Delfín, and Lower Delfín.…”

“…Consequently, the bathymetric expression of these two basins does not define the entire structural geometry due to the thick sedimentary cover. Recently, González-Escobar et al (2009, MarHernández et al (2012), and Martin- Barajas et al (2013) reported the depth of the acoustic basement (inferred from seismic two way travel time (TWTT)) of the northern Gulf of California, in some basins, at more than 7 km (Figure 2). At greater depths there is no seismic resolution, so it appears that the depth of the basement must be greater than these depths (>7 km).…”

The Gulf of California is an excellent example of how new ocean basins form. Tectonically, the northern Gulf of California is an incipient ocean basin and studies on it have defined acoustic basement and reveal the presence of new oceanic crust and intrusive bodies. Some recent studies report fundamental differences between the basins of the northern and southern Gulf of California: that the latter have well-developed oceanic crust beneath a thin cover of sediments, whereas the northern basins show proto-ocean basins, which may reflect thermal insulation of the thick sedimentary cover, the presence of lowangle faults, and more diffuse and distributed deformation. During the 1970s, Petróleos Mexicanos (PEMEX) undertook a 2D seismic reflection survey in the northern Gulf of California, over many active rift basins, including the Consag Basin. Through the processing and interpretation of these data, we describe the structural characteristics of the Consag Basin beyond 2 km depths. Using seismic reflection data, we identified an intrusion in the central part of this basin that may represent new oceanic crust buried by more than 4 km of sediments.

“…Geophysical studies confirm the presence of many active faults in the basins, and of a sedimentary column more than 5 km sediment thick (González-Escobar et al, 2009). The average heat flow in the Wagner and Consag Basins is 1875 mW/m 2 (Henyey and Bischoff, 1973;Prol-Ledesma et al, 2013), which is more than 15 times the mean oceanic heat flow (Davies and Davies, 2010).…”

Geothermal prospects in the Baja California Peninsula

a b s t r a c tGeothermal resource evaluation was accomplished for the Baja California Peninsula hydrothermal systems. Numerous geothermal areas were identified along the eastern coast of the Peninsula, which are related with the Gulf of California opening process. The western coast presents hydrothermal activity in the northern part related with regional faults like the Agua Blanca Fault nearby Ensenada. The southern part of the Peninsula also has abundant geothermal resources related with local grabens. The heat in place evaluation was accomplished for five geothermal areas where geophysical data were available to estimate the reservoir volume. The minimum calculated potential is more than 400 MWe. There are still more than six geothermal prospects with calculated temperatures above 200 • C that lack reliable information on the reservoir volume and would increase the geothermal potential of the Peninsula. Surface heat loss from the submarine systems reaches more than 6000 MWt.

“…1), which is defined locally by the rightlateral Imperial and Cerro Prieto faults; these faults are linked by the Cerro Prieto pull-apart basin, where the Cerro Prieto geothermal field is developed (Suarez-Vidal et al, 2008). The Cerro Prieto Fault continues southward into the Gulf of California where it accommodates transtensional deformation along the eastern margin of Wagner Basin (Gonzalez-Escobar et al, 2009). The Altar Basin (Fig.…”
