Our new target of geothermal resources is in 2000-5000m depth and temperature is over 350 degree celsius. In this region, the mechanical behavior of the rocks is considered to be ductile. In this study, we investigated the granite-porphyry system, located in central Akita Prefecture. As a results, homogenization temperature of these fluid inclusions indicate bimodal pattern and PT conditions of these mineral filling veins were estimated. We show the formation model of deep geothermal resource.
