cathodoluminescence and electron microprobe microanalysis are powerful tools in petrology and mineralogy. Observation of CL image of dating minerals such as zircons，monazite etc. by EPMA，combining use several compositional analyses an d image analyses techniques of electron microprobe for a integrate study，can re veal the internal texture and microarea composition distribution of zircons and obtain the information about evolution history and its relevant geological back ground of mineralogy and geochemistry of zircons，provide a good foundation for further study using techniques like SHRIMP，which has a higher sensitivity.
