Elemental distribution of turquoise gemstone is investigated using micro-PIXE technique. The RGB maps of the elements characteristic for turquoise gemstone were produced by means of PyMCA software. The experiments were performed on a suite of samples from different origins. The results show that both copper and phosphorous had already been collected in the aqueous solution of turquoise before its final positioning within aluminum bearing host minerals. Moreover, it is shown that the elemental composition of the host matrix could be considered as a distinguishing factor for determining the origins of the samples. Such information could shed light on the complicated formation process of turquoise gemstone and its provenance investigation, as this gemstone was a valuable commodity on the ancient trade markets.

使用micro-PIXE技术研究了绿松石宝石的元素分布。借助PyMCA软件生成了绿松石宝石特征元素的RGB图。对一组来自不同来源的样品进行了实验。结果表明，在将其最终定位在含铝主体矿物中之前，铜和磷都已经收集在绿松石水溶液中。此外，已经表明，宿主基质的元素组成可以被认为是确定样品来源的区别因素。这些信息可以揭示绿松石宝石的复杂形成过程及其物产调查，因为这种宝石是古代贸易市场上的宝贵商品。
