Abstract
The analytical precision of the Sr and the Pb isotopic compositions of natural samples obtained with a conventional ICP-MS is of 3 to 7x10(- 3) (internal 2 sigma) for the Sr-87/Sr-86 ratio, 6 to 8x10(-3) for the (206)pb/(207)pb and 1 to 4 x 10(-1) for the (206)pb/(204)pb and (207) pb/(204)pb ratios. Such accuracy is obtained with a procedure includin g a resin-chromatographic purification, a correction with respect to s tandard values (NBS 987 and 981) and a routine of four determinations for each sample. This procedure should allow rapid geochemical investi gations ahead of more precise determinations by thermo-ionization mass spectrometry.
