摘　　要：目的:应用不同鉴定技术鉴定及分析陕西省凤县铅硐山矿物药礜石的矿物学成分。方法:利用主要化学成分分析、微量元素光谱半定量、红外光谱、X射线衍射、X射线粉晶数据等测试技术对矿物药礜石进行鉴定。结果:主要化学分析(重量百分比)为Fe 36.63%,As 32.01%,S 31.75%,微量元素主要为Zn、Pb、Ag、Co、Nb、Cu、Ni等,杂质含量微弱,符合药材要求;红外光谱分析表明,礜石成分纯净,几乎百分百为毒砂;X射线衍射曲线表明,主要衍射线均为2.674、2.433,主要矿物为毒砂;X射线粉晶分析结果基本一致,成分纯净。结论:陕西省凤县铅硐山矿物药礜石实则为矿物学中的毒砂。Objective： To test different identification technology and identification of poisonous Stone mineral medicine to determine the mineralogical composition. Methods： The main chemical composition analysis, trace element spectrum semi quantitative, infrared spectroscopy, X-ray diffraction, X-ray powder diffraction data of different test technology for mineral medicine. Stone was identified. Results： The main chemical analysis （weight percentage） for Fe 36.63%, As 32.01%, S31.75%, trace elements are mainly Zn, Pb, Ag, Co, Nb, Ca, Ni etc., the impurity content is weak, with medicinal requirements; infi＇ared spectral analysis showed that the composition of pure stone, almost 100% of arsenopyrite; X-ray the diffraction curve shows that the main diffi＇action were 2.674 and 2.433, the main mineral is arsenopyrite; X-ray powder analysis results are basically consistent, pure elements. Conclusion： The stone is a solid mineral drug, the mineralogy of arsenopyrite.
