SEMARKONA
One
technique used heavily in our studies is cathodo-luminescence,
looking at the meteorite section under the microscope as it is bombarded with
electrons (cathode rays). The mineralogy and the trace and minor element
chemistry affect the cathodolumin-escence of the grains, so one is effectively
seeing composition and mineralogy, as well as structure. The images are also
very beautiful.
