The Initial Gradient of Sulfate in Gulf of California Sediments

Federico Paez-Osuna, Jose I. Osuna-Lopez

ABSTRACT

Results of pore waters sulfate analysis from 26 cores from the Gulf of California were used to calculate initial gradients of sulfate. The values range from 0.05 to 0.72 mM cm-1. The highest values are from the continental shelf; the intermediate and lowest values are from deep basins. Regression analysis between sedimentation rates and sulfate gradients gives an equation of the form w = -B(^dgrc/^dgrx)o, with an empirical constant B = 1.49. This constant differs from that obtained for marine sediments from other areas. This difference may be due to the fact that Gulf of California sediments apparently contain less reactive organic matter than do other marine sed ments with similar sedimentation rates.
