Abstract

Analysis of the Sr²⁺ concentrations of interstitial fluids obtained from sediments squeezed during Leg 115 were used to estimate the rates and total amount of recrystallization of biogenic carbonates. The total amount of recrystallization calculated using this method varies from less than 1% in sediments at Site 706 to more than 40% at Site 709 in sediments of 47 Ma. Results suggest that more positive Ca²⁺/Mg²⁺ gradients cannot necessarily be used as indicators of the nature of basement material. -from Authors
