“…Several studies in Guanajuato near to the study area similarly found also high concentrations of geogenic arsenic in groundwater wells with thermal activity (Landa Arreguín et al 2021;Morales-Arredondo et al, , 2015Rodríguez et al, 2006). It is related to the silicate weathering process in the region caused by water-rock interaction (Morales- Arredondo et al, 2020), then devitrification of volcanic glass and felsic rocks and finally the release of arsenic (Morales-Arredondo 2018). In the GZRN important concentrations of arsenic (Table 1) are also reported whose origin is related to: a) the weathering of volcanic rocks of the stratigraphic sequence in the study area of mostly acidic composition by the water-rock interaction; and/or, b) the leaching of As-bearing pyrite and finally its precipitation as As-bearing pyrite.…”

Thermal manifestations are commonly found in central Mexico as result of the volcanic activity originating from the formation of the Trans-Mexican Volcanic Belt during the Quaternary. The Rancho Nuevo hot spring is one of them that has not been described before with a discharge temperature near 92 °C. The goal of the present study is to provide geothermal characteristics of thermal manifestations at Rancho Nuevo location based on geochemical and mineralogical results to explain deep-subsurface processes that occurred in the geothermal system. The presence of kaolinite, montmorillonite, opal, zeolite, barite, pyrite, and stibnite in altered soil sediments or around the hot springs identified by the techniques used in the present study, confirms the presence of hydrothermal activity. In addition, based on the X-ray diffraction, calcite precipitates at the surface of the thermal springs. This mineral association reflects deep geothermal processes and is eventually deposited in shallow zones. Fluid mixing processes and variations in redox conditions are suggested by mineral association and isotopic sulfur data. Finally, based on the physicochemical data provided by the water samples and the discharge conditions of the springs, stability diagrams were constructed for pyrite, barite, and zeolites using the Geochemist's Work Bench program to corroborate these data with the mineralogical results. The mineralogical results and distribution, as well as the N-S trend of mineral associations suggest interaction processes between geothermal fluid and rocks of the stratigraphic sequence, and active major faults, enabling the upward flow of deep geothermal fluids. The approach to the conceptual model of the Rancho Nuevo geothermal prospect reveals an attractive potential for the exploration of a viable geothermal resource in central Mexico.

El objetivo del presente estudio es proporcionar las características geotérmicas de las manifestaciones termales localizadas en el poblado de Rancho Nuevo, considerando los resultados geoquímicos y mineralógicos, para explicar los procesos ocurridos a profundidad en el sistema geotérmico.
