摘要: 天山乌鲁木齐河源地区,从现代冰川末端(3650米)到望峰道班(3000米)附近,在绵延12公里的槽谷及其支谷之中广泛分布有不同成因类型的冰碛物,其中望峰道班附近的冰碛物,即本文所称望峰冰碛,在地貌形态、成因类型、组构特征等方面表现最为典型。根据地貌形态、砾石岩性组成上的差异,磨圆、风化程度,以及层位关系等方面的区别,望峰冰碛物可分为下望峰组和上望峰组。

Abstract: Distributive boundary line between the Lower Wangfeng and the Upper Wangfeng moraines and the eastern boundary of Lower Wangfeng moraine have been ascertained in this paper according to the features of the cross sections actually surveyed onthespot. Besides, the author has made a detailed study on the macroscopic and microscopic structures of longitudinal section of Wangfeng moraine and conclusions are as follows;1) Laminar structures are found in the moraine;2) The feature of concentrated accumulation exists in the moraine;3) Phenomena of overlapping of overfault and of folded fault in thesection are also seen.
