Abstract
We report here a few examples of trace element determinations in geological materials using a synchrotron microprobe at the Synchrotron Radiation Source (SRS), Daresbury. The experimental conditions were: beam energy of 15 keV, the energy bandwidth about 0.3 keV and the focussed beam spot was 15 × 20 μm2 FWHM. The following groups of minerals have been analyzed: olivines from basalt belonging to the Lower Silesian basaltic volcanic formation, Lower Silesia, Poland; feldspars, biolites and quartz from the so-called Rumburk granite known from the border-land of Germany, Poland and the Bohemian Massif; thucholite-like organic matter from the Lower Zechstein copper deposits of the Fore-Sudetic Monocline, Poland. The first, preliminary results and possible sources of errors are reported.
