| Summary: | The Scandinavian Promontory . — This remarkable promontory, extending for over a thousand miles from the Naze to the North Cape, is formed mainly of Archæan rocks, consisting of gneiss, crystalline schists, and other metamorphic rocks, penetrated by granite and other igneous dykes of later date. These primeval rocks are overlain throughout a portion of their extent by Cambrian and Lower Palæozoic (or Lower Silurian) beds, between which and the Archaean masses there is entire discordancy, and, as regards their respective ages, a long period of unrepresented time. The Palæozoic beds are themselves highly altered when in contact with the intrusive igneous masses, so that it is difficult to distinguish them from the more ancient masses in some districts. |
