U-Pb and U-series analyses of four U-rich opal samples using sensitive high-resolution ion microprobe SHRIMP demonstrate the potential of this technique for the dating of opals with ages ranging from several tens of thousand years to millions of years. The major advantages of the technique, compared to the conventional thermal ionisation mass spectrometry TIMS , are the high spatial resolution??? There are two major limitations to this method, determined by both current level of development of ion probes and understanding of ion sputtering processes. First, sufficient secondary ion beam intensities can only be obtained for opal samples with U concentrations in excess of???
