Hydrothermal alteration of upper oceanic crust formed at fast spreading rates

Project overview

Fast spreading rates occur at only 20% of the active ocean ridges, but approximately 50% of the present day ocean crust formed by fast spreading. Fast spread ocean crust is predicted to be relatively simple and most closely conform to the ideal Penrose stratigraphy. Here we wish to define the processes that govern the intensity and variability of chemical and isotopic exchange between seawater and basalts erupted at fast spreading rates, at a number of sites of different ages, extrusion styles, sedimentation rates, and basement topography. Chemical and isotopic fluxes calculated from these investigations will provide important tests of recent oceanic chemical balances for Sr, C, alkali elements, Si/Ge and U. This research will concentrate on Holes l256C and l256D drilled on ODP Leg 206, but also study Sites 595, 597, 1149, 1179, 1224 and 1243 that have received little attention.
