Geochemical Significance of Diagenetic Reactions in Ocean Sediments: An Evaluation of Interstitial Water Data (Extended Abstract)

Abstract

The gradients of dissolved calcium and magnesium, as well as those of delta super(18)O of the interstitial waters in deep sea sediments imply fluxes of material from layer 2 (oceanic basalts) into layer 1 (sediments) and vice versa. Especially the flux of H sub(2) super(18)O into layer 2 is significant and allows an estimate of the degree of alteration of layer 2 of the oceanic crust
