Application of Electron Microscopy on Volcanic Ash

This contribution is the result of a research project on volcanic ash from eruptions that affected the territory of Argentina. The study of volcanic ash is essential for knowledge and research in multiple disciplines, particularly in: Health, Industry, Air Navigation, Mining,, Water Supply, Soils and Environment. The instrumentation used was Philips XL30 ESEM Scanning Electron Microscope and EDAX Microwave Probe in volcanic originated particles [1]. This method advantages are of fast morphological and compositional observation, mineralogical and crystal assembly visualization, detection of mineral alteration. Surface microtextures, grain size and semi quantitative chemical composition are measured, this contribute to the characterization of volcanic episodes, and help to forecast possible future eruptions.
