| Abstract | Based on silica concentration of ground water for a 130 x 140 km area of the Ouachita Mountains, Arkansas a mean reservoir temperature of 44.3°C was calculated utilizing quartz solubility. Additional calculations obtain a mean heat flow value of 46.4 mQW/M2, geothermal gradient of 20.2°C/km and depth of water circulation of 1.4 km. This calculated geothermal gradient compares to other limited values ranging fro m18.2 to 45.6°C/km. |
