补充资料:冰水沉积
      冰川拖卸物经过冰川融水的搬运、分选而沉积的过程。它是冰川沉积过程中的一部分,包括冰河沉积、冰湖沉积和冰海沉积3类。
  
  冰河沉积  即冰川河流沉积。它是冰川作用地区最常见的沉积,有时也叫冰水沉积。较广泛地分布在山岳冰川和大陆冰盖的边缘或外围。冰川融水携带着大量经过磨蚀的砾石、砂、粘土和粉状物等,水流混浊,常呈乳黄或乳白色,称为冰川乳。当冰川融水流出冰川外围后,流速减慢,冰水携带物往往在终碛以下的谷地中停积下来,形成冰水沉积扇、冰水阶地;在冰帽边缘处则形成宽广而微起伏的冰水平原,如冰岛中部的霍夫斯冰川东侧的冰水平原面积达1900平方公里。
  
  冰河沉积物具有一定层理,主要由砂、砾石组成,粘土成分较少,与典型冰碛有明显区别。常见形态有:①蛇形丘,多分布在冰川边缘或前方,形态狭长而稍有弯曲,其走向大体平行于冰川流向,高数米至200多米,长数十米至 500多公里。主要见于北欧和北美古冰盖的边缘,现代冰川区少见。其成因有待进一步研究。②冰砾阜阶地,分布在山岳冰川前缘两侧的侧缘溪沟中,形态狭长,表面平坦,微向下游倾斜。由于埋藏冰块的融化,其表面形成许多凹坑;内部主要为有层理的砂、砾石等,时有不规则的透镜体。在冰舌边缘开裂处,沉积有形似坟墓的冰砾阜。
  
  冰湖沉积  即冰川湖泊沉积。发生在山岳冰川或大陆冰盖前缘一些湖泊中,冰川融水带来的细粒物质(有时含有堕石)进入湖泊后,在静水环境下缓慢地沉积在湖底。其特点是具有明显的很薄的韵律层理,每年形成一层,每层仅厚0.5~5.0厘米。每层的下部为浅色的夏季层,以砂土为主;上部为暗色的冬季层,以粘土为主,称为纹泥,又称季候泥。利用纹泥的纹理可以确定沉积物形成时期。此外,还有冰湖三角洲沉积和湖滨沉积等。
  
  冰海沉积  即冰川海洋沉积,指漂浮于海岸边缘的冰舌、 冰山、 冰棚中所挟带的冰碛在海洋底部的沉积。它较广泛分布于海??,如围绕南极有一个宽达370~1300公里的现代冰海沉积带。
