摘要
采用常规宝石学特征测试及红外光谱仪(FTIR)、激光剥蚀电感耦合等离子体质谱仪(LA-ICP-MS)、紫外-可见分光光度计(UV-Vis)等现代测试方法,对软玉"黄口料"的宝石学特征及颜色成因进行了研究。常规宝石学特征测试表明"黄口料"的宝石学特征与其他软玉品种一致。FTIR及LA-ICP-MS测试结果共同说明"黄口料"的主要矿物组成为透闪石。LA-ICP-MS及UV-Vis分析结果表明Fe^(3+)对"黄口料"颜色的形成有重要作用,Mn^(2+)对黄绿色有抑制作用,Ti元素对其颜色也有影响。
The gemmological characteristic, mineralogical composition and cause of colour of “ Huangkouliao” samples are studied by the means of several conventional gemmological methods, FTIR, LA-ICP-MS and UV-Vis,etc. The results show that MHuangkouliaow sam-ples conform with nephrite characteristics. FTIR and LA-ICP-MS show that ^Huangkou- liaow nephrite is dominated by tremolite. LA-ICP-MS and UV-Vis reveal that Fe3＋ promotes the colour of “ Huangkouliao” nephrite; and Mn2＋ inhibits green colour and Ti also has af-fects on the colour.
