More geological information can be obtained from very small samples due to the analytical technique development toward trace elements and in micro area. Within all of the microprobe techniques, the laser ablation inductively coupled plasma mass spectrometry(LA-ICPMS) has became even more powerful tool to geological samples in the quantitative analysis of major and minor element in   situ owe to the very high sensitivity of ICPMS and direct laser sampling. Many works have done in minor element and REE normalization modeling, trace metal and PGE partitioning in minerals and magma, fluid inclusions and isotope age dating analysis. The LA-ICP-MS technique is capable not only of achieving precise trace elemental analysis, but also of dating ²⁰⁷Pb/²⁰⁶Pb ages at about the 1% level for?1000 Ma zircons,²⁰⁶Pb/²³⁸U ages with precision of 2%~5% for Mesozoic(156~126 Ma)zircons. lt is likely that this simple and relatively low cost technique is able to achieve age results even comparable to the SHRIMP-type ion probe in the measurement of the relatively large(>100μm) and homogeneous zircons. However, it still has the disadvantage of lower spatial resolution and sensitivity, standard samples incomparable with some samples to be analyzed, which limits its application to precise analyzing minerals with relatively lower REE and dating of small and/or heterogeneous zircons of Phanerozoic ages. Recently developed laser ablation multiple collector inductively coupled plasma(LA-MC-ICPMS)put forward the isotope concentration in situ analysis technique in sensitivity and simplicity. Multiple using of varies in situ techniques for combined information is the new trend in analytical geochemistry.
