The 4.5 km deep IDDP-2 drill hole was drilled at Reykjanes, Iceland, in an active seawater-recharged hydrothermal system on the landward extension the Mid-Atlantic Ridge. Drilling targeted a well-defined hydrothermal up-flow zone feeding the Reykjanes geothermal reservoir, which produces fluids comp...
