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.
