Relationship of geothermal surface manifestations with the geology of northeastern Mexico, according to the interpretation of magnetic, gravimetric, and electrical resistivity data

We present geophysics data analysis from northeastern Mexico in areas with superficial geothermal manifestations. We interpreted magnetic anomalies reduced to the pole, gravimetric anomalies, and 2D electrical resistivity tomography models. The results show that the superficial geothermal manifestations are associated with deep or shallow faults in NW-SE and NE-SW directions. These faults may be the main outlet conduits for thermal fluids to the surface and their dynamic activity may constitute a great heat source for the fluids. This heat can also be associated with the cooling of igneous rocks and the radioactive decay of geological materials.
