- ItemShallow anatomy of hydrothermal systems controlled by the Liquin?e-Ofqui Fault System and the Andean Transverse Faults: Geophysical imaging of fluid pathways and practical implications for geothermal exploration(PERGAMON-ELSEVIER SCIENCE LTD, 2022) Perez-Estay, N.; Molina-Piernas, E.; Roquer, T.; Aravena, D.; Vargas, J. Araya; Morata, D.; Arancibia, G.; Valdenegro, P.; Garcia, K.; Elizalde, D.We combined geoelectric and seismic ambient noise methods to image the shallow depth (<30 m) distribution of thermal waters in two fault-controlled hydrothermal systems located in southern Chile. The bedrock depth was constrained with seismics, while hotsprings and mapped faults were imaged by low-electrical-resistivity domains (<160 omega m) defined with electrical resistivity tomographies (ERT). The distribution and shape of low-resistivitydomains suggest that thermal fluids follow complex pathways, including deep vertical conduits hosted in fractured rock and shallow horizontal bodies hosted in sediments. These results indicate that the studied hydrothermal systems are at least twice longer within the sediments than the superficial area covered by hotsprings.
