Rubidium and Strontium chemistry of oceanic crust
Times of vein mineral deposition in the ocean crust have been determined both by Rb-Sr isochron ages of vein smectites and by comparison of 87Sr/86Sr ratios of vein calcites with the known variations of seawater 87Sr/86Sr ratio with time. Results from drilling sites 105, 332B and 418A, Atlantic Ocea...
