| Abstract: | Different micro dating methods have been developed in recent years,the advantages and disadvantages are simply introduced at first.The recent development of electron microprobe chemical dating method in the age research of uraninite/pitchblende and the used analytical conditions by the precurser are presented in detail by stages.Finally,the application foreground of this method in the age research of uraninite/pitchblende and the possible problems are systematically investigated and discussed.It is believed that this method will play a big role in the age research of uranium minerals,especially in the micro dating research of tiny uranium minerals（φ10 μm）and uranium micro-ores of multi-stage. |
