Summary | In the framework of a collaborative project funded by the Mexican government, we applied Magnetotellurics and Transient Electromagnetics in two geothermal areas located in Michoacán, a state placed in the central part of Mexico. These geothermal areas (Araró and San Agustín del Maíz) are located around Cuitzeo lake, where several geothermal surface manifestations have been reported. In Araró, a total of 31 MT stations and 30 TEM soundings were acquired. Whereas, in San Agustín del Maíz, we only acquired 21 MT soundings. At both areas, the soundings were spatially distributed around the locations of the thermal springs and water wells with high temperature. The acquired MT time series were robust processed to estimate the transfer functions. We perform the 3D inversion modeling of both MT data sets using ModEM. Regarding the TEM data, we interpreted them using 1D Occam and Marquardt techniques and the derived information was integrated in the corresponding 3D MT inversion scheme. Finally, the 3D resistivity models are appraised and correlated to geochemical and geological data, that were also obtained within the framework of this project. |
