角闪石族矿物的研究

本文通过对角闪石族矿物的化学成分、光学性质、X射线粉晶数据,晶体结构等资料的综合研究,提出了角闪石的命名系统,对比了各种角闪石的物理性质和晶体参数,讨论了晶体结构,化学性质、类质同象置换规律,水的作用。固溶体关系、镁铁闪石问题、鉴定特征和产状等几个主要方面的问题.这对了解矿物的形成条件和分布规律,以及解释各种复杂的地质现象问题有一定的意义。

A Rearch Report on Amphibole Group

In this paper, a new system o, nomenclature pertaining to amphibolic mineral groups is proposed on the ground of synthetic study on their chem- ical composition, optical properties x-rayograms of crystaline grains, crystal structure and etc. Moreover, the comparisons on various amphiboles in relation to their physical properties and their crystal parameters; the discussions on respective crystal structure, chemical properties, law of isom- orphous substitutions, role of water, solid-solution relationship, major probl- ems with cummingtonite, distinguishing features and occurence are also dealt with in more detail. All these not only develop the right sense for better understanding in the primary requisites to mineral formation and underground distribution, but also provide helpful aid for explaining various sorts of complicated geological phenomena.
