“Meteorite Analyses Using the Electron Microprobe”

Abstract:  The electron microprobe is an offshoot of the scanning electron microscope. High-energy electron beams are "shot" at a target which in turn produces emissions of high-energy waves of various wavelengths. The microprobe, in essence, acts like a spectroscope by analyzing the spectra of these emissions and identifying the various elements in the sample by using their characteristic wavelengths.  Recent analyses of a series of meteorites from Libya using the new microprobe facility at the Harrison Schmidt Research Facility of the Planetary Studies Foundation's University of Illinois - Chicago labs was undertaken by Dr. Dod during his sabbatical last year. The results of that study will be discussed here as it was at UCLA this past August during the International Meteoritics Society meeting.
