冰碛地貌

冰碛物堆积的各种地形总称冰碛地貌。它是研究古冰川和恢复古地理环境的重要依据。主要的冰碛地貌有冰碛丘陵、侧碛堤、终碛堤、鼓丘等。

冰碛丘陵是冰川消融后,原来的表碛、内碛、中碛都沉落到底碛之上,合称基碛。是大陆冰川地区分布最广的冰碛,多成片分布,低洼处沉积较厚,高地很薄,呈波状起伏,相对高度数十米到数百米,洼地往往积水成湖,又称冰碛湖。

侧碛堤是由侧碛堆积而成的,侧碛是冰舌两旁表碛不断由冰面滚落到冰川与山坡之间堆积起来的,有一部分则是山坡上的碎屑滚落到冰川边缘堆积而成的。冰川退缩后,在原山岳冰川两侧形成条状高地、即侧碛堤。

终碛堤由终碛堆积而成。终碛是冰舌末端较长时期停留在同一位置,即冰川活动处于平衡状态时逐渐堆积起来的。多呈半环状。大陆冰川的终碛堤比较低,高约30—50米,但可长达几百公里,弧形曲率小,山岳冰川的终碛堤比较高,可达数百米,但长度较小。

鼓丘是一种主要由冰碛物组成的流线形丘陵,通常高数十米、长数百米长轴与冰流方向平行,迎冰面陡而背冰面缓。
