Abstract:

Concentration gradients of Ca, Mg, K, Sr, and Li at Site 462, Leg 61, are linear with depth; large changes occur in the unsampled, low-porosity limestone-chert zone between 375 and 445 meters. Correlations between Ca and Mg are linear, but breaks occur in Ca-Sr and Ca-K correlations. These breaks imply release of strontium in the limestones (recrystallization of carbonate) and uptake of potassium (formation of authigenic K-feldspar?).
