对产于美国阿拉斯加的异性石的物理特性及化学成分进行分析.该异性石呈深红色,为一轴晶正光性;其紫外可见吸收光谱在530 nm处有明显的吸收带,在917 nm处有较弱的吸收带;穆斯堡尔谱及参数与俄罗斯科拉半岛深红色异性石和辽宁凤城深玫瑰色异性石相近;红外光谱特征与正光性异性石相似.探讨了该异性石的致色机理,认为其颜色主要与Fe2+有关,且异性石中的Fe2+主要以平面四配位存在.

The eudialyte from Alaska is crimson and optically positive. Optical absorption spectra of the eudialyte are characterized by obvious absorption band at 530 nm and weak absorption band at 917 nm. Its physical properties, chemical composition and Mossbauer spectrum are similar to the crimson eudialyte from Kola peninsula in Russia and the deep Rose eudialyte from Fengcheng in Liaoning province. And its infra-red spectrum is similar to that of the optically positive eudialyte. According to research of E. V. Pol' shin and Hanxueming, author thinks the colour of the eudialyte from Alaska is related to Fe2+ and Fe2+ in the eudialyte is mainly in a planar four-fold coordination.
