Examples of heterogeneity in maps generated by LA-ICP- (ToF)MS. ad and ek: Gold particles from the Similkameen River, BC, Canada. l, m: particles from Cunningham Creek, BC, Canada. n,o: gold particles from Eldorado Creek, Yukon, Canada. ae: examples of heterogeneity in elements normally detectable using EPMA. fj: trace element distribution in mineral inclusions. ko: localized concentrations of specific elements above background levels (‘clusters’). Color keys indicate signal responses corresponding to different intensities in different images. In each case, the associated numerical key is the measured signal intensity and a qualitative indication of concentration
