QUANTITATIVE SIMS ANALYSIS OF TRACE AU IN PYRITE USING THE INFINITE VELOCITY (IV) METHOD

The quantitative analysis of trace concentrations of Au in pyrite usin g 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 concentration s of Au in pyrite using standard-derived relative sensitivity factor ( RSF) and IV quantification methods is shown as a means of evaluating t he chemical environments in which Au is found in pyrite.
