Fig. 6From: Mass fractionation of Rb and Sr isotopes during laser ablation-multicollector-ICPMS: in situ observation and correction87Sr/86Sr and 85Rb/86Sr ratios determined with the standard bracketing method. Vertical error bars denote 2 standard errors. Total average ratios are marked as gray dotted lines. Red dashed lines represent recommended values of 87Sr/86Sr (Woodhead and Hergt 2001) and 85Rb/86Sr (Jochum et al. 2011)Back to article page
