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. |
Author(s): | Karlsson, H. R. Jakobsson, S. J. Moore, James G. |
Date: | 1992. |
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. |
