地热田位于武义盆地东侧从杨家至徐村一带,长约25km,宽约5km.根据地热水的水化学分析,应用SiO2和Na/K地球化学温标估算出热储温度为81℃~110℃,热储深度为800~1163m.地热水的氢、氧同位素组成及氚同位素测年表明,它的来源与现代大气降水有关,但不是区内当地的地表水,而是武义盆地外围较高山区(高程大于300m)的地表水.
Geothermal field is located in the east of Wuyi Basin from Yang to Xu Village area, about 25km, width of 5km. According to the hydrochemical analysis of geothermal water, the temperature of thermal storage is estimated to be between 81 ℃ and 110 ℃ and the thermal reservoir depth is between 800 and 1163m, using SiO2 and Na / K geochemical temperature scales. Hydrogen and oxygen isotopic composition and tritium isotope dating of geothermal water show that the source of the geothermal water is related to the precipitation of the modern atmosphere but not to the local surface water in the area but to the surface water in the higher mountainous areas (elevation> 300m) outside the Wuyi Basin .
