“…Geodetic block modeling, along with previous geological assessments of slip direction, have revealed an increased occurrence of faultperpendicular extension toward the southeast (3%-10%) and northwest (5%-15%), with lower values observed throughout the central part of the fault (<2%) (Wetmore et al, 2019). Notably, the zone of the ABF with the highest extension coincides with the location of the hottest thermal waters along the coast of the Punta Banda Peninsula, specifically at La Jolla beach (LJB, 94°C) and at a submarine fumarole (SMF, 102°C) (Carbajal-Martínez et al, 2020;Vidal et al, 1981).…”

Amagmatic geothermal systems within regional‐scale orogenic faults are promising renewable resources for heat and possibly electricity production. However, their behavior needs to be better understood to improve their exploration and assessment of energy potential. To provide more insight, we report geochemical, geological, and geophysical studies from seven hot spring sites strung along a 90 km segment of the Agua Blanca Fault, which traverses a mountainous region of northern Baja California, Mexico. Our results show that topographic heads drive infiltration of meteoric water deep into basement rocks, where it is heated according to the local geothermal gradients. Long paths lead to long water residence times and high 3He/Hetotal fractions. The hot water ascends along preferentially permeable zones within the ABF, discharging at temperatures from 37°C in inland springs to 102°C on the Pacific coast. Higher discharge temperatures correlate positively with the degree of extensional fault displacement (a proxy for fault permeability). Correlations between hydraulic head gradients, residence times, and 3He/Hetotal of the thermal waters show that the hydraulic head gradient controls the length and depth of the flow paths, whereas the magnitudes and locations of the discharge sites are controlled by fault permeability. Optimal conditions at the coast allow the 120°C temperature threshold for electricity production to be reached at relatively shallow depths (<2 km), demonstrating the potential of orogenic geothermal systems not only for exploitation of hot discharging water but also for EGS exploitation of the hot rocks that surround the water upflow zones.

“…[18][19][20][21][22][23] However, it is also necessary to study the effect of other secondary salts such as carbonate, sulfate, and phosphate on the stability of GO in water-particularly at concentrations relevant to environments such as arid and semi-arid regions, where the concentrations of these salts can be as high as 1293 mg L À1 , 1695 mg L À1 , and 30 mg L À1 for carbonate, sulfate, and phosphate, respectively. 24,25 Furthermore, considering that water surface temperatures can reach values close to 70 C in coastal semi-arid areas and 40.7 C in arid regions, [24][25][26] temperature could also have an important impact on GO stability in water. Therefore, it is necessary to understand how a Centro de Investigación y de Estudios Avanzados del IPN (CINVESTAV), Unidad Saltillo, AV.…”

“…Latin America remains one of the world's most important geothermal energy markets. This includes 12 South and Central American countries and Mexico in the north (Carbajal- Martínez et al, 2021;Chacón-Hernández et al, 2021;Diezmartínez, 2021;González-Acevedo et al, 2018;Hernández-Morales et al, 2021;Pérez-Denicia et al, 2017). Although geothermal energy currently constitutes a small part of the energy sources of Latin America and the Caribbean, this situation is changing, and many countries are building and expanding geothermal energy plants and facilities with the cooperation of the American Development Bank.…”

Factors such as fossilisation, diversification of energy resources, sustainable development, and energy security are attracting global attention for the development and expansion of renewable energy sources. Environmental issues arising from fossil fuel consumption are being addressed, but concerns remain about the renewability and availability of new energy sources. Mexico is one of the ten countries in the exploitation of geothermal energy, with a history of approximately five decades. This study examines Mexico's five major geothermal fields: Cerro Prieto, Los Azufres, Los Humeros, Las Tres Vírgenes, and Domo San Pedro. Currently, Mexico is working with international geothermal companies. However, there are more power plants and substantial cooperation to obtain this energy for industry and homes. This study is focused on the potential of geothermal exploitation in Mexico and its position worldwide after the introduction of geothermal energy in Mexico. Next, five geothermal fields are introduced in Mexico, and the potential and capacities of each are discussed. Finally, the future energy scenarios in Mexico are reviewed, with an emphasis on geothermal energy.
