| 摘 要： | 针对珠宝市场上新近出现的一种田黄仿制品——"印尼金田黄"(市场俗称)进行了XRD,ICP-MS及FTIR等大型仪器的系统分析测试,并对其矿物组成、化学成分等方面进行了系统的分析,并与寿山田黄进行了对比。研究结果发现,"印尼金田黄"主要为方解石矿物组成,与寿山田黄的矿物组成完全不同;其化学全分析结果显示,除Ca外,Mn,Fe等变价金属离子元素的质量分数较高,可能是导致"印尼金田黄"呈现金黄色的主要致色原因。无论其矿物组成、化学成分还是常规宝石学特征,均与传统的、以地开石为主的寿山田黄完全不同。

| Abstract: | By using XRD,ICP-MS and FTIR,a systematic research is carried out on the mineral components,chemical compositions and gemmological characteristics of Gold Tian Huang from Indonesia which appears in the current jewelry market as a new imitation of Tian Huang.The results show that the Gold Tian Huang from Indonesia is mainly composed of calcite.The elements analysis indicates that besides Ca,high amount of transitional-metal ions such as Mn and Fe,may be the main reason for the golden yellow colour of the Gol... |
