“…On the basis of our data, the NE-striking faults are explained as the normal faults accommodating extension, while the NNW-striking faults play the role of transfer faults, accommodating differential extension (e.g. Brogi et al, 2020;Gibbs, 1990;Liotta, 1991;Lister et al, 1986;Olvera-García et al, 2020;Wheeler & Rosendahl, 1994). The second kinematic event, recognized on the transfer faults, accounts for regional uplift, reworking pre-existing discontinuities, such as the two recognized fault systems.…”

“…the two fault systems, suggesting that the consequent increase of permeability related to contemporaneous activity on both systems controlled the upflow of the hydrothermal fluids (e.g. Brogi et al, 2012;Curewitz & Karson, 1997;Olvera-García et al, 2020;Rowland & Sibson, 2004). In most cases, hydrothermal mineralization extends laterally, following the contact between the intrusive body and the carbonate rocks, indicating that mechanical discontinuities such as bedding and lithological boundaries acted as lateral reservoirs, when hydraulically connected with the upflow of fluids.…”

“…Se ha observado que escenarios estructurales favorables permiten el ascenso de fluidos geotérmicos a la superficie con temperaturas entre los 70 y 100 °C (e.g. Taillefer et al, 2017;Olvera-García et al, 2020a). Según Olvera-García et al (2020a), en la zona geotérmica de SAM, la intersección de fallas (OSO-ENE y NNO-SSE) da lugar a un gran volumen de roca deformada y a la formación de pipe-like structures (e.g.…”

“…La zona geotérmica de San Agustín del Maíz (SAM) en Michoacán, se ubica en la ribera sur de la cuenca tectónica del Lago de Cuitzeo (Figura 1), localizada a 30 km al norte de Morelia (Michoacán). Esta zona es afectada por una tectónica regional con una extensión de dirección aproximada NO-SE (Pasquaré et al, 1988;Suter et al, 1991Suter et al, , 2001Ego y Ansan, 2002), la cual ha permitido la formación de fallas normales de dirección SO-NE y OSO-ENE, así como fallas laterales de dirección NNO-SSE; estas últimas juegan el papel de fallas de transferencia (Figura 1b) (Olvera-García et al, 2020a). Este escenario ha permitido la formación de cuencas tectónicas orientadas SW-NE, donde se han depositado los sedimentos lacustres antes mencionados (e.g.…”
