N2 - Deep Magneto-Telluric (MT) and Mise-a-la-Masse (MAM) geophysical imaging methods provide valuable information on fundamental processes within a geothermal field. However, because of an inherent non-uniqueness problem during data processing, interpretation of each individual method sometime has no good agreement with a real geological structure in a geothermal field. As a result, the naive application of the methodology can lead to erroneous results. Therefore, to convince the interpretation result by decreasing non-uniqueness possibility, we have performed integrated inversion of MT and MAM data observed in the Sibayak geothermal field, Indonesia. The results were then correlated to borehole data. The final interpretation show a dome-shape structure of the low resistivity, indicating an up-flow zone around fractures in the southeast direction of the Sibayak Mountain. This geophysical information is useful for the task of selecting sites for the promising zone in the Sibayak geothermal field.
