瘦长红珊瑚是台湾贵珊瑚中最主要的品种, 其颜色分布独具特色。 以瘦长红珊瑚为研究对象, 采用电子探针、 X射线粉晶衍射、 红外光谱和拉曼光谱对其进行测试分析。 结果显示样品的矿物成分为高镁方解石, 次要成分的含量稳定, 样品中的生物成因方解石存在晶格畸变。 实验探测到的代表有机质成分的1 517/1 128 cm-1和1 296/1 016 cm-1成套谱峰表明样品的红色与该有机成分有关。

Corallium elatius, which has unique color distribution characteristic, is the most important species of Taiwan precious corals. EPMA, XRD, FTIR and Laser Raman detective methods were used to study the chemical, mineral composition and spectra characteristics of Corallium elatius. The result of EPMA, XRD and FTIR shows the high-Mg calcite mineral component and the stable minor chemical constituents of the samples. Meanwhile, the cell parameter indicates the lattice distortion and the preferred orientation of calcite grain caused by organic matter. The red part of the samples shows a different Raman spectrum from that of the white part, located at 1 517/1 128 cm-1 and 1 296/1 016 cm-1. Raman scattering measurement reveals the relationship between the organic matter and color.
