Abstract: In this paper, a review on commentary thesis on geo-analysis technology and method in nearly 20 years is reviewed and assessed, including geo-analysis technology and method, sample pretreatment technology(sample decomposition, separation and enrichment), measurement technology and methods. The measurement technologies include inorganic determination (whole analysis, microanalysis, isotope and geochronology methods), organic(compound) analysis, environmental radioactive measurement. At last, the current hot topics and future development trends of geo-analysis technology are highlighted.
