| Abstract | At the Kakkonda geothermal area, Japan, a large Quaternary granitic body is dstributed below ca 2.5 km ckpth from the surface, associating with thick high-temperature contact me&amorphic zones in the overlying formations, and a meteoric-water-cbminated type hydrothermal system is developedat present time. During the 'Deep-seated Geothermal Resources Survey', WD-la well was drilled to 3729 m depth,& a thermal conduction zone with a maximum temperature over 500?C was observed in the Quaternary granitic body. |
