Ion Microprobe Silver Isotopic Analysis in Native Silver
Abstract Mass and energy spectra of native silver minerals from ore deposit Ducat were studied with the Cameca ims-4f ion microprobe. SIMS depth profiles of 107Ag+ and 109Ag+ secondary ions and 109Ag+/107Ag+ ratio were measured. The change of this ratio in studied minerals and difference of the shape of energy spectra of 107Ag+ and 109Ag+ secondary ions were found. It was revealed that these parameters depend on temperature conditions of minerals formation. A model explaining the observed effects is discussed.
