Abstract

Trace-element compositions of hundreds of geological turquoise samples from Zhushan, Ma’anshan areas in China and Kingman area in America were measured by ICP-MS. The data reveals that trace elements of turquoise from these three areas can be differentiated by Linear Discriminant Analysis. The result shows that it is feasible to restrict the possible provenance of ancient turquoises based on linear discriminant analysis of trace elements in Chinese ancient turquoise artifacts.
