| 摘 要： | 作者用光学方法、电子探针分析方法、红外吸收光和Ｘ射线粉晶衍射方法对豫南高压麻粒岩中的富钛角闪石类进行了详细。结果表明这些富钛角闪石可分别属于钛角闪石类和成分的宇镁绿钙闪石的富钛角闪石类。它们系幔源偏碱生镁铁质岩类成分相当的原岩子高压麻粒岩相变质条件下再平衡后的变质残余矿物和重结晶矿物。

| Abstract: | This paper presents the detailed studies of Ti rich amphiboles from high pressure granulites in southern Henan Province by means of optical analysis,electron microprobe analysis,infrared absorption spectrometry and single crystal X ray diffraction.It is shown that these Ti rich amphiboles belong to kaersutites and Ti rich amphiboles whose composition is similar to magnesian hastingsite,respectively.They were formed from the re equilibration and re crystallization minerals in the process of metamorphism from mantle source protolytes of subalkalic mafic composition under the high pressure granulite facies of the metamorphic condition. |
