Abstract
AbstractA magnetotelluric study was carried out in the San Pedro‐Linzor volcanic chain, North Chile, to identify possible magmatic structures and hydrothermal systems associated with volcanoes of Holocene activity, considering previous petrochemical studies pointing to crystallization depths of approximately 8 km. Three‐dimensional resistivity models based on magnetotellurics data of the San Pedro‐Linzor volcanic chain were obtained based on broadband data measured in 2017 and 2018, in addition to long‐period data measured in 1990s. The three‐dimensional modeling shows two low‐resistivity zones (less than 10 Ωm) interpreted as partially molten areas below the Chao Dome and the Paniri volcano, and a shallower low resistivity area (less than 5 Ωm) in the Turi Basin, an active hydrothermal system to the southwest of the volcanic chain.
