| | Abstract | | The effective exploration of geothermal resources requires dense geophysical data acquisition over a large area with reasonable time. Also, the accurate and reliable methodology/technique is required to interpret the acquired geophysical data quantitatively. The airborne electromagnetic is one of the proper geophysical methods for this type of survey and interpretation. In this paper, we have studied interpretation methods, which include three one-dimensional methods and a three-dimensional method, of the airborne time-domain electromagnetic data acquired by JOGMEC in 2015 over Hachimantai area, Iwate prefecture, Japan. It was demonstrated that results by all these methods agreed reasonably well and the interpreted models agree with the structure interpreted using land electromagnetic data and resistivity-log data. The characteristics of the resistivity distribution were discussed using the resistivity model interpreted from airborne time-domain electromagnetic data acquired over a known geothermal area. |
