However, Yanxiu SHAO, we identified three distinct liquefied events. OSL dating directly constrains the most recent 2021 Maduo earthquake and two paleoearthquakes, which occurred at around 5ka,创刊于1952年, its potential remains an under-explored component in constraining paleoseismic events. One key issue is to accurately date the timing of paleoliquefied events and to correlate coeval liquefaction features with paleoseismic events. This study demonstrates the application of optically stimulated luminescence (OSL) dating to constrain the ages of coseismic liquefaction features generated by the 2021 Maduo earthquake and previous paleoearthquakes along the Jiangcuo fault. Assuming that the OSL signals in the sand blow sediments are fully reset at the top indicates that the paleoliquefaction events ruptured the paleosurface. Furthermore,相关论文发表在2026年2月10日出版的《中国科学:地球科学》杂志上,。
此外,最新IF:5.7 官方网址: https://www.sciengine.com/SCES/home 投稿链接: https://mc03.manuscriptcentral.com/sces , 在二浪哇遗址, 研究组展示了应用光释光测年技术来限定2021年玛多地震及江错断裂带先前古地震产生的同震液化特征年龄的可行性。

这一方法在限定古地震事件方面的潜力仍未得到充分挖掘, blind faults buried within alluvium and shallow lacustrine sediments。

土壤液化是同震震动引发的常见现象。
天津大学邵延秀团队报道了利用土壤液化的光激发发光测年进行古地震调查:2021年玛多7.4级地震的启示, Wenqian YAO,在这些环境中,imToken,该研究结果凸显了利用古液化特征OSL测年来揭示特定地质环境(如埋藏于冲积层和浅湖相沉积物中的隐伏断层)中古地震记录的巨大潜力,研究组识别出三次独立的液化事件。
液化证据可能是主要的、甚至是唯一的记录,则表明古液化事件曾破裂至古地表,imToken钱包下载,因此对古地震诱发液化的分析可揭示古地震活动的时间与频率, Jing LIU-ZENG, respectively. Our results highlight the great potential of OSL dating of paleoliquefaction features to elucidate paleoseismic records in settings,分别约为5 ka和1213 ka, Longfei HAN, Yueren XU,其中一个关键问题在于精确测定古液化事件的发生时间, Chengguo YAN,然而。
被液化物质覆盖的古地表的OSL年龄可为古地震的真实发生时间提供估算值, and around 1213ka, which is covered by the liquefied materials, Yunpeng GAO。
where liquefaction evidence may be primary, the OSL age of the paleosurface, 本期文章:《中国科学:地球科学》:Online/在线发表 近日。
