ABSTRACT Postglacial faults in Sweden are generally believed to have ruptured to the surface once either during or shortly after the late Weichselian deglaciation. Stratigraphic data from multiple scarps support or are consistent with this hypothesis and, until now, no data refute it. This study presents geomorphic evidence that a segment of the Merasjärvi fault in northern Sweden ruptured to the surface at least twice. The timing of the fault ruptures is poorly constrained because the scarp lies within a preserved glacial landscape. Crosscutting relationships indicate that the scarp is younger than the early Weichselian but suggest that parts of the scarp existed beneath the late Weichselian ice sheet.

瑞典北部梅拉斯耶尔维“冰后断层”多次表面破裂的地貌证据

摘要 瑞典的冰后断层通常被认为是在魏克塞尔晚期冰川消退期间或之后不久破裂到地表。来自多个陡坡的地层数据支持或符合这一假设，直到现在，还没有数据反驳它。这项研究提供了地貌证据，表明瑞典北部的 Merasjärvi 断层的一部分至少破裂到地表两次。断层破裂的时间限制很差，因为悬崖位于保存完好的冰川景观中。横切关系表明陡崖比早期魏克塞尔期更年轻，但表明部分陡崖存在于晚期魏克塞尔期冰盖之下。
