AbstractElectron probe microanalysis (EPMA) is a fundamental analysis technique for the study of the Earth and planets materials. In the last decades, EPMA has been developed from its essential capacity of analyzing major elements for minerals to a series of innovative technologies, including trace-element analyses in crucial minerals, precise analysis of rare-earth minerals, chemical dating of accessory minerals, Fe3+ determination in Fe-rich minerals, and applications of field-emission gun EPMA (FEG-EPMA) and soft X-ray emission spectrometer (SXES). However, there are still many challenges in such innovative technologies as follows : (1) how to lower detection limit and improve the precision and accuracy; (2) how to eliminate the influence of the secondary fluorescence effect; (3) establishing new analytical and correction methods under low accelerating voltage conditions by using FEG-EPMA. EPMA analyses are expected to have great potentials involving the development of reference standards, secondary fluorescence effect correction, broad applications of FEG-EPMA and soft X-ray emission spectrometer, improvement of spectrometer and integration of multiple microbeam techniques. Therefore, EPMA would provide further abundant and accurate micron-scale information for geological samples.
