青海阿尼玛卿冰川构造

该区冰川构造十分复杂,具有多层次、多期次的变形特点。本文论述了冰川构造层次的划分,分析了各层次构造的形成,特别是对冰川下部韧性变形带中被动式褶皱的生成环境及其运动学和动力学的特点进行了讨论。冰川可作为观察、研究构造的天然模型,对其研究将加深对地壳上各种构造形态的认识和理论探讨。

THE GLACIER STRUCTURE OF MT. ANIMAQING

The glacier structures at Mt. Animaqing, Qinghai province, are quite complicated, and they are characterized by multiple levels and phases of the, tectonic deformation. This paper deals with the division of deformation levels of these glacier structures , the development of the structure of individual level, and especially with the deformation circumstances of the passive folds at the lower level of glacier where the ductice strain Zones developed. The deformed glacier can be considered as a natural model for studying structural features of rocks, that may be a great help to geologists with the study of structural development of the crust.
