摘要阿尔卑斯山造山带和加里多纳德造山带的结构和构造演化除了有许多不同之处外，还表现出几个共同的特征。这些相似之处意味着造山过程中的基本相似之处，构成了一个简短比较研究的起点。作为参照的阿尔卑斯样带是穿过瑞士东部的中央阿尔卑斯山，这与欧洲大地导线的踪迹不谋而合。在喀里多尼德山脉中，以挪威南部的索格内峡湾断面为例，该断面是最近一项结构汇编的主题。两者都以构造图的形式和以相同比例尺绘制的地壳剖面图的形式出现，每一种情况下的构造单元都根据其前造山联系来区分：克拉通前陆、裂谷大陆边缘和大洋杂岩。尽管这两个造山带具有各自复杂的前造山构造，但它们的造山演化可以用一系列具有特征的阶段来描述：前造山带、造山带、造山带和造山带。
Abstract The structure and tectonic evolution of the Alpine and Caledonide orogens show several common features in addition to the many contrasts. These parallels, taken to imply a basic similarity in orogenic processes, form the starting point for a brief comparative study. The Alpine transect used as reference is that through the Central Alps in eastern Switzerland, which coincides with the trace of the European Geotraverse. In the Caledonides, the Sognefjord transect in southern Norway, the subject of a recent structural compilation, is taken as illustration. Both are presented in the form of a tectonic map and crustal cross-section drawn at the same scale, with the tectonic units in each case distinguished according to their pre-orogenic affiliation: cratonic foreland, rifted continental margin and oceanic complex. In spite of the individually complicated pre-orogenic architectures, the orogenic evolution of both orogens can be described in terms of a series of phases with characteristic features: pre...
