| Abstract: | The quantitative analysis of trace concentrations of Au in pyrite using a new procedure of SIMS quantification is investigated. Analysis of an Au implanted pyrite standard demonstrates the infinite velocity (IV) method as a viable procedure for evaluation of trace concentrations of Au in pyrite. Comparison of naturally occurring trace concentrations of Au in pyrite using standard-derived relative sensitivity factor (RSF) and IV quantification methods is shown as a means of evaluating the chemical environments in which Au is found in pyrite. |
