Oxygen Isotope Studies of Fresh and Weathered Submarine Basalts
Abstract
The 18 O/16 O ratios of fresh unmetamorphosed basalts from the Reykjanes, Mid-Atlantic, and Gorda Ridges and the East Pacific Rise fall in a narrow range of 5.5–5.9‰ (SMOW), identical to those of basalts from oceanic islands. Large plagioclase xenocrysts in some of the basalts are not in isotopic equilibrium with coexisting olivine. The basalts react with sea water at the ambient sea-floor temperature to form clays, resulting in an increase in δ 18 O of the basalt of 0.25‰ per m.y. This provides a very sensitive method to detect early stages of weathering, which otherwise might go unnoticed. Advanced submarine weathering of basalt can remove nearly one half of its SiO 2, MgO, CaO, and Na 2 O and lesser amounts of Al 2 O s and TiO 2. Weathering does not proceed deeply enough into the basaltic sea floor to affect the chemical composition of sea water. Since it is likely that large amounts of basaltic debris (less than a few cm in radius) are on the ocean floor, their weathering can affect the ocean-sediment budget of TiO 2, Al 2 O 3, SiO 2, MgO, and CaO.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
