土石缓滑.
土石缓滑或泥流(英语:Solifluction)
是对一种缓慢土石流动的统称。因为冰的冻融活动,使土石流向斜坡下移动。 这是现代对土石缓滑的标准定义,但与 Johan Gunnar Andersson 在 1906 年的原始定义不同。[1]
[2]
最初,它是指在冰缘地区,土石流因含饱和水而移动。然而后来发现,冰缘地区各种缓慢的土石流活动不需要水饱和,而是与冰的冻融过程有关。[1][2]
这一词就被用来这些缓慢的地质作用,而不包括在冰缘的快速流动[1]。在缓慢的冰缘流动中,没有清晰的滑行平面。[3]因此,就不包含表皮流动活动和滑脱分离运动不包括在概念中。[1]另一方面,在任何潮湿的气候中,浸透在水中的废物堆都可能发生移动,因此土石缓滑一词不限于寒冷的气候。
土石缓滑在冰缘分为四种类型:[1]冰蠕动(英语:Ice creep)、霜冻蠕动(英语:Frost creep)、
凝胶流(英语:Gelifluction)、塞式流动(英语:Plug-like flow),土石缓滑的慢速作用比某些地球化学或其他侵蚀过程慢得多[1][2]由于土石缓滑与湿度和寒冷气候有关,因此可用于推断过去的气候。[1]
