3 Citations (Scopus)


The Reykjanes hydrothermal system contains a highly saline (Cl 19 260 ppm) circulating fluid at depth, due to influx of sea-water, whereas at Krafla the fluid is non-saline meteoric water. Extensive oxygen isotope exchange has occurred between the hydrothermal altered rock and the circulating fluid in the Krafla geothermal field. The Krafla hydrothermal fluid has delta 18O = - 11.9per mille and delta D = -86.8per mille. -R.A.H.
