Geology of Las Minas: an example of an exhumed geothermal system (Eastern Trans-Mexican Volcanic Belt)

Abstract: The Las Minas area corresponds to an exhumed geothermal system considered a proxy for the deep part of the nearby Los Humeros active geothermal system. The stratigraphic succession is made up of: Palaeozoic-Miocene granitoids, a thick Jurassic-Cretaceous carbonate succession, Neogene lava flows and volcano-sedimentary deposits. Linked to a Miocene magma intrusion, marble and skarn rock-volumes developed by contact metamorphism and geothermal fluid flow. Faults are arranged in SW-and NNW-striking systems. These… Show more

“…6g; after Norini et al, 2019) that much (or completely) resembles the first proposal of Campos-Enriquez and Arredondo-Fragoso (1992). However, such a conceptual model is now under stress as the geothermal anomalies appear very localized, mainly confined along the NNW-SSEtrending Maxtaloya-Los Humeros-Loma Blanca-Los Conejos corridor and corresponding to the almost unique, narrow, rapidly declining, thermal anomaly recognized within the Los Potreros caldera (Norini et al, 2015;Peiffer et al, 2018;Jentsch et al, 2020). This geothermal configuration is Ferriz and Mahood (1984).…”

“…2b) and the Rinconada Fault Zone (Fig. 2c) are located in the Las Minas area, a fossil and exhumed geothermal system considered as an analogue of the active geothermal system of Los Humeros [32]. Strong analogies are mainly referred to the fracture pattern, distribution, and kinematic indicators of fault surfaces of the deep part of Los Humeros reservoir [33], characterized by fractured limestones faulted and intruded by dykes.…”

“…In this study, the comprehensive geophysical method with CSAMT as the main method and TEM as the supplemental one was used to achieve relatively ideal results in exploring geothermal resources in the magmatic rock areas. Compared with other geophysical or geological methods [30,[52][53][54][55][56][57][58], the comprehensive geophysical method possesses significant advantages: By using the comprehensive geophysical method, the various elements of the geothermal system can be displayed. In addition, both thermal cap in shallow and magmatic rocks as the thermal reservoir in deep can be clearly described, and the water-conducting fault as the migration channel of geothermal fluid can also be delineated in detail.…”
