Abstract

Summary

The Musadake geothermal field area is located at the eastern Hokkaido, Japan. Geothermal explorations such as geological and geophysical surveys had been carried out in this area and successive drilling was conducted. Recently the JOGMEC conducted helicopter-borne geophysical surveys such as AGG and HELITEM in the area. Subsequently to these surveys, a high-resolution aeromagnetic survey has been conducted using a stinger mounted helicopter-borne system to better understand the detailed subsurface structure. The survey was aimed mainly at locating intrusions associated with geothermal resources and their boundaries in which geothermal fluid can be transported. The resultant high-resolution aeromagnetic map and 3D magnetic imaging results imply the relationship between the magnetic structure and geothermal signature as well as the existence of an unknown intrusion along the structural boundary.
