Structure and property of some hydrous phases whose stability field correspond to that of upper mantle of the earth have been studied. It was found that there is probably continuous solid solution between hydrous and anhydrous wadsleyite. Small degree of Mg-Si disorder was found in the structure of hydrous ringwoodite. With increasing pressure, shifts of OH-stretching vibration band to higher wave numbers were observed in phlogopite, while shifts of OH-stretching vibration band to lower wave numbers were observed in muscovite. Structural behaviors of phase A and chondrodite under pressure were found to be similar to that of forsterite.

研究了与上地幔稳定性场相对应的几种含水相的结构和性质。结果表明，含水和无水硅铝石之间可能存在连续固溶体。在水化后的林伍德石结构中发现了少量的Mg-Si无序。随着压力的增加，金云母中OH伸缩振动带向高波数方向移动，而白云母中OH伸缩振动带向低波数方向移动。A相和软骨石在压力下的结构行为与镁橄榄石相似。
