摘　　要：利用激光显微拉曼光谱仪,对市场上俗称"鸡血石"的6块产地不同的样品进行测试分析。测试得到6块样品的特征拉曼光谱,可为无损鉴定提供一定参考。临安市昌化镇玉岩山的3块鸡血石样品的"血"为同一种矿物,均为辰砂(Hg S);"地"包括地开石、高岭石、明矾石或石英等不同的矿物成分。临安市潜川镇紫溪村的鸡血石样品"血"为赤铁矿(α-Fe2O3),"地"为纯度较高的地开石。桂林鸡血石样品"血"为赤铁矿,而"地"是硬度较高的石英。贵州鸡血石样品的"血"是辰砂,"地"是黑色、灰色的碳酸盐矿物。各样品测得的X射线粉晶衍射数据结果与激光显微拉曼光谱数据一致。Six pieces of chicken-blood stones from different origins are tested and analyzed with a laser micro- Raman spectrometer. Characteristic Raman spectra of the 6 stone samples are obtained and helpful for the non- destructive identification of chicken-blood stones. ＂Blood＂ of the 3 pieces of chicken-blood stones from Yuyan Mountain, Changhua Town, Lin＇an, is cinnabar （HgS）. The main mineral composition in Di of the 3 samples is different, which probably contains dickite, kaolinite, alunite, quartz or other minerals. ＂Blood＂ of the sample from Zixi is hematite （α-Fe2O3） and its Di is high purity dickite. ＂Blood＂ of the sample from Guilin is hematite and its Di is quartz. ＂Blood＂ of the sample from Guizhou is cinnabar and its Di is carbonate mineral. The data tested by X-ray powder diffraction are consistent with that by laser micro-Raman spectroscopy.
