| Abstract | The Matsukawa geothermal field is, located in the lIachimantai volcanic region in which three geothermal power plants are now in operation(Fig.l), The Matsukawa power plant commenced its operation in 1966. and is characterized by a vapor dominated geothermal system. Some conceptual models of the Matsukawa area based on the surface survey data and well data were proposed(Hayakawa,1967; Nakamura,1967; Ide,1985). In addition to these models. a geological structure of the Matsukawa area was explained in detail by Akazawa and Muramatsu(1988). For the last 22 years, chemical characteristics of steam and production rates of the wells changed with the Matsukawa geothermal system discharge characteristics with compositions of steam. |
