Resource Assessment of Vartun Geothermal Region, Central Iran
Editorial
Abstract
Vartun geothermal region (VGR) is located in west central part of Iran, 300 km in the southeast of Tehran. VGR area is 277 km2and there are some geothermal surface manifestations such as warm springs and travertine deposits. There are three warm springs which their temperature varies from 35.3 to 43.1 °C. Their pH is a little bit acidic and is about 6.1-6.2. Based on geothermometery studies Vartun geothermal reservoir approximate temperature was estimated 46-182 °C. According to the geological, aeromagnetic and remote sensing studies VGR probable reservoir and cap rock was recognized. Therefore Permian dolomite, limestone and sandstone were regarded as reservoir rock while cap rock includes shale and quartzite. Thermal energy of Vartun geothermal resource was estimated 1.14 × 1017kj.
