Fig. 9From: Fluid flow through the sedimentary cover in northern Switzerland recorded by calcite–celestite veins (Oftringen borehole, Olten) 87Sr/86Sr of whole rock carbonate, vein calcite and vein celestite versus depth along borehole. The range of 87Sr/86Sr in seawater at the time of deposition of each lithostratigraphic unit is shown as grey boxes (McArthur et al. 2001). Unless visible, error bars (2σ) are smaller than the symbol sizeBack to article page
