Abstract:The Particle Phase Analysis (PPA)method by means of Quanta 200 scanning electron microscope (SEM),GENESIS energy disperse spectroscopy (EDS)can analyze particle size and phase automatically.A systematic experimental is carried out to verify the PPA method in this study,using samples of Cenozoic basalts from Datong.We apply the PPA method of EDS to study the thin section and polished section in the geological field for the first time,which yield a series of morphology and chemical composition data of different phases such as phase types,particle number of each phase,average diameter,area, roundness,length-width ratio,chemical composition.The proportion and average particle diameter of each phase can also be obtained as well,overcoming the shortages of traditional method in thin section and polished section.It proves that PPA guar-antees significant data for the study of mineralogy,petrology and ore deposit geology.
