摘要: 阿尔泰山区第四纪冰川作用规模巨大,冰川作用遗迹丰富多样。由于交通条件限制,除新疆地质局区测大队1978年对哈拉斯河流域第四纪冰川作过一些工作外,很少有人进行详细研究。作者在1980年时,有机会对哈拉斯河流域第四纪冰川进行观察,现整理成文,以供参考。

Abstract: During the Quaternary, the glaciation in the Altay Shan of China reached a magnificent scale. Abundant and numerous traces of ancient glaciation exist in the Altay Shan of China. In the drainage basin of Halasi River, there develop tiering cirques, U-shape valleys and beaded-stringlike lakes, special features of ancient glaciation in the western mountains of China. According to the elevation of the exposure of moraines, weathering condition and their correlation, it was found that during the Quaternary, at least two glaciations, the Halasi glaciation (Late Pleistocene) and the glaciation of the Middle Pleistocene (ice sheet) happened and since Holocene one Neoglaciation of Akekule and the Little Ice Age of Youyi Peak took place in this region also. In Quaternary glaciation, the formation of peneplain before glaciation bore profound influence on type, scale and regime of glaciation.
