Journal Article: Surface Exploration Of The Theistareykir High-Temperature Geothermal Area, Iceland, With Special Reference To The Application Of Geochemical Methods

Abstract
The surface exploration of the Theistareykir high-temperature geothermal area in northeast Iceland is reported. The results of stable isotope and Cl determinations are used to characterise the origin of the fluid, gas geothermometers to indicate underground flow temperatures, and major gas ratios. Rn, and Hg concentrations to infer permeability, boiling conditions, upflow locations, and flow directions. These results are used in conjunction with geological and geophysical studies to construct a model of the geothermal system, whose main features are upflow zones under the northeast and southwest parts of the geothermally active surface area, with a cooler zone between, which could result from poorer permeability and additional cooler inflow. A suggestion is made as to the siting of the first exploratory well in the Tjarnaras area close to the southwesterly upflow area.
