Geochemical well logs were used to measure the dry weight percent oxide abundances of Si, Al, Ca, Mg, Fe, Ti, and K and the elemental abundances of Gd, S, Th, and U at 0.15-m intervals throughout the basement section of Hole 504B. These geochemical data are used to estimate the integrated chemical exchange resulting from hydrothermal alteration of the oceanic crust that has occurred over the last 5.9 Ma. A large increase in Si in...
