作者用光学方法、电子探针分析方法、红外吸收光谱方法和 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研究。结果表明这些富钛角闪石可分别属于钛角闪石类和成分近于镁绿钙闪石的富钛角闪石类。它们系幔源偏碱性镁铁质岩类成分相当的原岩于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。
The authors studied the titanium-rich hornblende in high-pressure granulite in the south of Henan Province by optical methods, electron probe analysis, infrared absorption spectroscopy and X-ray powder diffraction. The results show that these fullerenes amphiboles belong to the category of the amphiboles and the titanium-rich amphiboles whose composition is near that of the magnesiite. They are the metamorphic remnant minerals and recrystallized minerals under the condition of high-pressure granulite facies metamorphism under the condition of mantle-derived alkaline mafic rocks.
