本文扼要地介绍了用X射线衍射强度数据估算闪石族矿物各阳离子占位的方法。实测数据证实 ,这不仅在理论上是可能的 ,而且在实验上也是可行的。无论是钙质闪石还是碱性闪石 ,估算精度多数达到 90 %左右 ,可满足晶体化学研究之需。以估算的占位数按国际分类表判定的闪石种属与按成分分析的相比 ,两者的符合率达 80 %～ 85% ,从而否定了前辈学者“闪石族不能用X射线粉末法研究”的断言 ,在这一问题上取得了突破性进展。 This paper briefly introduces the method of estimating the occupancy of each cation of the amphibole minerals by X-ray diffraction intensity data. The measured data confirm that this is not only theoretically possible, but also experimentally feasible. Calcium amphibole or alkaline amphibole, the majority of the estimated accuracy of about 90%, to meet the needs of crystallographic research. The coincidence rate of the amphibole species determined by the international classification table with the estimated number of occupancies is 80% ~ 85% compared with that by the component analysis, thus denying that the scholar of the amphibole can not use X-ray powder Legal research "assertion, made a breakthrough on this issue.
