Oxygen isotope studies of hydrothermally altered basalts from Surtsey, Iceland / H.R. Karlsson, S.J. Jakobsson, James G. Moore.

Title: Oxygen isotope studies of hydrothermally altered basalts from Surtsey, Iceland / H.R. Karlsson, S.J. Jakobsson, James G. Moore.

Publisher: Rotterdam: Balkema
Abstract: Oxygen isotope ratios of hydrothermally altered rocks from 181 m core through Surtsey island record cumulative effects of 12 years of low-temperature alteration of basaltic tephra. δ¹⁸O values (6 to 12%) appear to be governed by formation of palagonite and its subsequent isotopic exchange with sea water. This is reflected in two trends in the δ¹⁸O-H₂O⁺ relationship of samples. Trend A shows correlation similar to that of altered deep-sea basalts. Trend B is consistent with oxygen isotopic exchange between palagonite and progressively hotter fluid.
