北太平洋的晚白垩世历史未被恰当地解释,主要是由于在白垩纪的磁平静期发生了板块大改组。利用原始资料,根据断裂带走向和晚白垩世海底扩张磁异常重建板块运动,允许系统地阐述可解释北太平洋地区(特别是天皇海槽和奇努克海槽)所有地质特征的合理的事件顺序。在 The Late Cretaceous history of the North Pacific has not been adequately explained, mainly due to a major plate shuffling during the magnetic calm of the Cretaceous. The use of primary data to reconstruct the plate motion based on the strike of the fault zone and the Late Cretaceous seabed dilatational magnetic anomalies allows for a systematic exposition of a plausible sequence of events that explains all the geological features of the North Pacific Ocean, especially the Emperor’s Trophy and the Chinook Trough. in
