Precise dating of the activity of Late Pleistocene to Holocene neo‐tectonic structures is crucial to quantify the rate of deformation in low‐seismicity regions. Sardinia is a relatively stable continental fragment set in the middle of the tectonically active Western Mediterranean belt. This paper provides evidences of significant uplift of northwest Sardinia that support an ongoing tectonic activity since the Marine Isotopic Stage 7 (MIS 7; ca. 220 ka). In particular, it documents for the first time Late Pleistocene to Holocene tectonics based on luminescence dating of travertine sealing a major NNE‐SSW fault.

地中海南部撒丁岛晚更新世断层的发光年代,作为隆起和活跃构造的证据

晚更新世至全新世新构造构造活动的精确年代对量化低地震活动区的变形速率至关重要。撒丁岛是一个相对稳定的大陆性碎片,位于构造活跃的西地中海带中部。本文提供了自海洋同位素第7期(MIS 7;220 ka)以来西北撒丁岛大量隆升的证据,支持了正在进行的构造活动。特别是,它首次基于钙华的发光年代测定法密封了一个主要的NNE-SSW断层,记录了晚更新世至全新世构造。
