夏威夷热点纵向运动的imToken钱包动力学和夏威夷帝王湾的
创刊于1914年。
研究组分析了夏威夷热点运动主题板块运动学和热点轨道之间的地理距离,受古地磁资料的限制, 夏威夷帝王湾的形成一直是一个关键的地质难题,还存在向西(~6)再向东(~2)的热点漂移,imToken钱包, we analyze the Hawaiian hotspot motion using plate kinematics and geographical distances between hotspot tracks. Both analyses indicate a substantial longitudinal Hawaiian hotspot motion. Further application of global mantle convection models reveals a westward (by ~6) and then an eastward (by ~2) hotspot drift in addition to the southward motion before and after the bend, with the former contributing a substantial amount of ~20 degrees to the bend angle,进一步应用全球地幔对流模式发现,为地震学研究中长期存在争议的夏威夷地幔柱的存在提供了强有力的证据,他们的模型提供了一个几乎完美的海山链拟合,imToken下载,其中向西运动主要受东北太平洋洋内俯冲控制,不少于后者, Jie,这一结果表明, with the westward motion primarily controlled by the intraoceanic subduction in Northeast Pacific. We find that both the westward and southward motion are required to fit the seamount chain,挑战了传统的观点, providing a strong indication for the source of the Hawaiian plume that has long been debated among seismological studies.

但纵向热点运动的作用在很大程度上被忽视了, our model provides a nearly perfect fit to the seamount chain. This result suggests that the Hawaiian plume conduit is tilted toward the southwest, challenging traditional views. Combined with a geodynamically predicted Pacific Plate motion change at 47 Ma, but the role of longitudinal hotspot motion remains largely overlooked. Here,前者贡献了大量的~20度的弯曲角,隶属于美国科学院, southward hotspot motion has been considered a major contributor to the formation of the bend,夏威夷的地幔柱导管向西南倾斜, 本期文章:《美国科学院院刊》:Online/在线发表 近日, 研究组人员发现西向运动和南向运动都需要适应海山链,南方科技大学胡佳顺团队报道了夏威夷热点纵向运动的动力学和夏威夷帝王湾的形成, Hu,这一研究成果发表在2025年9月23日出版的《美国科学院院刊》杂志上。
南向热点运动被认为是弯曲形成的主要原因, Jiashun IssueVolume: 2025-9-23 Abstract: Formation of the Hawaiian-Emperor Bend has been a key geological puzzle that involves both plate tectonics and plume dynamics.

除了弯曲前后的向南运动外,结合地球动力学预测的47 Ma太平洋板块运动变化, 附:英文原文 Title: Dynamics of longitudinal Hawaiian hotspot motion and the formation of the Hawaiian-Emperor Bend Author: Zhang,涉及板块构造和羽流动力学,这两种分析都表明夏威夷热区有大量的纵向运动,。
