振动光谱对四川平武锡石的矿物学特征研究

研究矿物的振动光谱特征并结合矿物的主量和微量化学成分及晶体晶胞参数特征会更有效地了解晶体结构、颜色等矿物特征[1],因此通过镜下观察和采用X射线衍射、红外光谱、扫描电镜、拉曼光谱等大型仪器,分析了四川平武锡石的主要构成成分与晶体结构;影响颜色、环带和造成金刚光泽的主要因素;锡石中汽液包体的成分等,从而全面了解四川平武锡石的矿物学和宝石学特征。

Vibrational Spectra Study on the Mineralogical Characteristics of Cassiterite in Pingwu,Sichuan Province

Studies of Vibrational spectra characteristics,major and trace chemical composition of mineral and lattice parameter characteristics of mineral crystal are helpful to understand crystal structure,color and other characteristics.In order to comprehensively master the mineralogical and gemological characteristics of cassiterite in Pingwu,the main components,crystal structure,major factors influencing color and girdle of cassiterite,major initiating factors of luster of diamond,vapor-liquid xenoliths in Pingwu′s cassiterite were analyzed through microscopic observations and measurement of vibrational spectra of cassiterite by using X-ray diffraction,IR spectra,SEM,and Raman spectra and other large-scale instruments.
