伊比利亚冰川之地:冰川如何塑造山脉
伊比利亚,冰川之地:冰川如何塑造山脉讨论了过去冰川对伊比利亚当前景观的影响。目前,比利牛斯山脉最高峰只有一些小冰川,它们是19世纪末结束的最后一个寒冷时期的遗留物:小冰河时代。然而,对伊比利亚半岛最高峰和相邻山谷景观的准确观察揭示了一个由数百米厚的冰川连续通过而形成的过去,类似于今天在阿尔卑斯山或巴塔哥尼亚发生的情况。
伊比利亚冰川作用导致冰在山谷中扩张,这些山谷现在被公路网使用,是重要人口定居的地方;此外,这些冰川沉积的大量沉积物如今仍然不稳定,可能会给山区人口带来风险。《伊比利亚冰川之地》(Iberia,Land of Glaces)从更具教育意义的角度介绍了冰川对山脉景观的影响,每个地区的专家编写了21个伊比利亚地块的例子。
Iberia, Land of Glaciers: How The Mountains Were Shaped By Glaciers
Iberia, Land of Glaciers: How The Mountains Were Shaped By Glaciers discusses the impact of past glaciers in the current landscape of Iberia. Currently, there are only small glaciers in the highest peaks of the Pyrenees that are the legacy of the last cold period that ended at the end of the 19th century: The Little Ice Age. However, an accurate observation of the landscape of the highest peaks and adjacent valleys of the Iberian Peninsula reveals a past shaped by the successive passage of glaciers with hundreds of meters of ice, similar to what happens today in the Alps or Patagonia.
Iberian glaciation has resulted in ice expansion through valleys that are now used by the road network and where important populations settle; in addition, large accumulations of sediments deposited by those glaciers are still unstable today and can trigger risks for mountain populations. Iberia, Land of Glaciers presents the impact of the glaciers in the landscape of mountains following a more educational perspective with examples of 21 Iberian massifs written by specialists from each of the areas.
