Abstract

This study aims to interpret the geological model of the subsurface geothermal area Ratai Way of magnetic data and its correlation with surface geothermal manifestations. The study begins by performing magnetic measurements, magnetic data processing to obtain the total magnetic anomaly. Then performed upward continuation to reduce the influence of shallow effects, and reduction to the pole. The value of magnetic anomalies reduced to pole results have a range between -350nT to 400nT. Low value of magnetic anomalies are interpreted in the center area of research related to the existence of geothermal manifestations. To get a model of the subsurface structure is done by using a 3D inversion modeling Mag3DC program. 3D modeling results show susceptibility range of 0.00 up to 0.0075. Groups of low magnetic anomaly is a young volcanic deposite (Qhv) that consists of andesitebasalt lava, breccia and tuff who suffered alteration. Of magnetic anomalies and the surrounding landscape, supposedly an area of research is out flow and up flow in Mount Ratai.
