摘要: 闻名世界的青藏高原是地球上山岳冰川作用较为强烈的地区之一,古代和现代冰碛物广泛分布。本文是在野外工作的基础上对青藏高原一些冰碛物中的粘土矿物差热分析结果提出初步看法,以期对第四纪冰期划分和冰碛物研究提供一定依据。

Abstract: Through the differential thermal analysis of the clay minerals in some tills on the Qinghai-Xizang plateau, it is found that the illite is the main substance in them. In the southeastern part of Xizang and the western section of Himalaya where the maritime climate is influential, in the tills besides illite, there are many other transitional minerals. Judging from the differential thermal data of tills a in different geolo-igcal periods, the content of clay mineral increases with the age. Furthermore, from the theory of evolution of clay minerals, it is preliminarily suggested that the Pleistocene climatic change in the Southeast Xizang and West Himalaya was greater than at present, i. e. the climatic variation in the past glaciaylacinl and interglacial periods was great and the in-terglacial climate was much warmer than today.
