Chemical microanalysis by x-ray microscopy near absorption edge with synchrotron radiation

Abstract
The use of synchrotron radiation is shown to give promising properties to x‐ray absorption microanalysis. Geological samples, 30 μm thick, have been analyzed over large areas with a few micrometers resolution, and maps of transition‐metal distributions were obtained in less than 15 min. An increased resolution is expected with x‐ray resists.
