| 摘 要： | 辉石是最重要的造岩矿物之一。无论是研究火成岩,变质岩,还是研究深部地质或月球岩石都离不开辉石的鉴定和研究。在工艺岩石学(例如铸石学)的研究中辉石鉴定问题也极为重要,尤其是X射线粉末法鉴定。因此,近五十年来很多人对辉石的X射线粉末图进行过研究。为了研究辉石类质同象对晶格常数的影响及其和成因的关系,各种辉石(主

| Abstract: | In this paper three diagrams determined the compositions of clinopyroxenes with X-ray powder method are plotted by the present authors according to a great deal of data for the synthetic and natural specimens (incluses new seven analyses). The three diagrams are as follows:1) the universal diagram for all clinopyroxenes using 2θ510 and 2θ50 (Cu Kα) (Fig. 1);2) the diagram determined the composition of the clinopyroxenes in the system Ca-Mg-Pe using 2θ(311)-2θ(310) Cu Kα and d150 (Fig. 2);3) the diagram determined the clinopyroxenes in the system of Jd-Ac-Di-Hd using d150 and refractive index α (Fig. 4).A linear relation between the volumes of unit cell of clinopyroxenes and the mean radii of cations also is given. |
