本文利用傅立叶变换红外光谱技术对产自河北汉诺坝新生代玄武岩中的4个单斜辉石巨晶进行了微量结构水的观察．确定3SOOcm‘左右和3620cm－‘左右两组峰为结构OH吸收峰，其中3500cm(-1)‘左右是主要特征吸收峰。单斜辉石巨晶自源区被携带至地表的过程中未经历明显的红扩散丢失。结合文献中的资料可以认为，上地幔中水的分布可能是不均一的。
In this paper, Fourier transform infrared spectroscopy (FTIR) was used to observe the microstructure water of four clinopyroxene giants in the Cenozoic basalts from Hannoba of Hebei Province. The two groups of peaks around 3SOOcm ’and 3620cm-’ were identified as OH absorption peaks, of which 3500cm (-1) ’was the main characteristic absorption peak. The clinopyroxene giant mesoma has not undergone obvious loss of red diffusion during its being transported to the surface from the source region. According to the data in the literature, the distribution of water in the upper mantle may not be uniform.
