在伸展过程中，大陆岩石圈变薄并破裂，根据伸展岩石圈的热机械状态形成宽或窄的裂谷。北美科迪勒拉山脉和爱琴海地区的大陆裂谷宽度可达 1,000 公里，已得到广泛研究。然而，由于缺乏远端被动边缘的地震可解析数据以及缺乏陆上自然暴露，从广泛的大陆裂谷到大陆分裂的演化过程仍然是个谜。在这里，我们表明始新世横跨南海北缘的延伸记录了宽阔的大陆裂谷和高度延伸之间的过渡（
During extension, the continental lithosphere thins and breaks up, forming either wide or narrow rifts depending on the thermo-mechanical state of the extending lithosphere. Wide continental rifts, which can reach 1,000 km across, have been extensively studied in the North American Cordillera and in the Aegean domain. Yet, the evolutionary process from wide continental rift to continental breakup remains enigmatic due to the lack of seismically resolvable data on the distal passive margin and an absence of onshore natural exposures. Here, we show that Eocene extension across the northern margin of the South China Sea records the transition between a wide continental rift and highly extended (
